Native Seeds in Restoration: Garlic Mustard Treatment Part 2 – Seed Mix & Site Prep

Posted on by Tuula Rebhahn

In fall of 2022 RNPP measured out a couple of vegetable-garden sized squares of bare earth along the Rogue River and initiated the trial of a specially blended riparian seed mix. 

Our goal? To learn how to best apply native seeds to revegetate sites that have been smothered by invasive plants and treated with herbicide for over a decade. 

Project background and site prep were covered in the first blog post in this series, but to recap: At these two garlic mustard “demonstration sites”, we put down a native seed mix that contains species that do well in shady riparian areas. After the seeds have germinated, we will monitor the seeded areas for species diversity and compare them to “control” area where no native seeds will be added. We predict that the results will show a better coverage of native plants on seeded areas. 

At both the John Day Rd. site and the ODFW site, blackberry and garlic mustard have long suppressed natural regeneration of native plants. Garlic mustard itself is allelopathic, preventing native seeds from germinating. Finally, some of the treatment methods used involved broad-spectrum herbicides sprayed across all vegetation at the site, meaning only overstory trees survived. 

In this blog post, we will discuss the seeding mix and methods used at the demonstration sites, as well as a new seeding technique we’re excited about involving divots!

Seeding Strategy Overview

The scope of this project is not to revegetate all of the 100+ acres that have been affected by garlic mustard. Instead, the goal is to trial a specialized native seed mix and seeding strategy that can achieve some of the land management goals at the site (stabilize soil, prevent new invasives from moving in, provide habitat), and can be applied to larger areas in the future. 

The “demonstration sites” where this seed mix is being trialed measure 10×20 meters (roughly 32×64 feet). These plots are divided into two “treatment” areas (seeded) and two “control” areas (unseeded). 

Species Selection 

To choose which species to include in this seed mix and begin restoring native plant diversity to the treatment areas, we first had to consider seed availability. We knew we wanted to “go heavy” with a large number of seeds per square foot, to give the plants a better chance at competing with invasives. We also anticipate some herbicide drift occurring through continued spot-spraying for garlic mustard and other weeds, resulting in some unintended die-off of young native plants. 

Through the Rogue Native Plant Partnership, we were able to secure seeds for 19 different species in large enough quantity to be sown over an area totaling 1/10 of an acre. Most of the seeds used were collected in the wild around the Rogue basin, and some came from locally farmed seed lots. Availability also determined the ratio of forb, grass and woody species seed; while we have access to plenty of milkweed seed, woody plant seeds are not so abundant. 

We also spoke with the herbicide applicators who have worked at these sites for years. Their observations were valuable for learning what species have come back naturally in some of the areas sprayed for garlic mustard. These included some of the grasses used in the mix. 

Combining this intel with general knowledge of the species that compose riparian understory communities in the region, we came up with the following species list: 

Some of these species were also chosen for their ability to grow quickly and compete with invasive plants, for instance, lupine, snowberry and tarweed. 

Seed Mix

To create the seed mix shown in the graphic above, we used the seed mix calculator linked to in this blog post. That post has a detailed discussion of how to determine your seeding rate, taking you from a species list in-hand to a calculated seed mix with a balanced proportion of each species – we highly recommend it!  

For this demonstration seeding we determined that a fairly high seeding rate, 100 seeds/square foot (or 72 lbs/acre) would be most effective. 

Prepping & Seeding

As described in the first blog post in this series, the areas to be seeded had been treated for weeds before we arrived. That’s ideal for restoration planting – because native plants do not compete well with invasives, pre-treatment is needed.

Photo on left of demonstration site after garlic mustard treatment. Photo on right after raking and lightly marking out rows to place divots.

To improve soil contact with the seeds, we raked the entire demonstration site (plot). Then we checked our measuring tapes to mark out the “control” (no seeds) and “treatment” (to be seeded) sub-plots. These sub-plots alternate because environmental variations like topography and shading from overstory trees on one end of the plot or the other could bias our results, and we wanted to reduce that bias. The alternating sub-plot layout is shown in Figure 1. 

Having checked our layout and measurements, we proceeded to the treatment sub-plots to make our divots and sow the seed. 

Divots? What are divots?!

Divots are small impressions in the earth that mimic the footprints of a large animal like an elk (which roam the riverbanks around our demonstration sites). The technique was developed for seed-based restoration projects in the harsh arid environments of the US southwest (Bainbridge, 2007). The theory is that by placing seed in the divots, the seed is less likely to be blown away by wind or washed away by rains, while the divots may help protect the seed from drying wind and sun. The technique has been used on other projects here in southwest Oregon with successful results. 

Vesper Meadow site that was treated with a tarp to smother weeds, then replanted with pollinator seed mix in divots.

For these demonstration sites, we used a hoe to make small impressions in the soil (no more than ½ inch deep), spacing them about a foot apart. A total of 50 divots were created in each 5×10 meter subplot, and a handful (about 1/10th of an ounce) of seed was added to each divot. 

Larger image of multiple divots in the soil, arranged in rows. Closeup image of the quantity of seed mix placed in each divot.

Finally, we raked each seeded sub-plot lightly again to provide some soil coverage to the seeds while maintaining the divot structure. 

Now, We Wait

Habitat restoration with native seeds takes time; while it may look like nothing is happening on the surface, all winter long, seeds are responding to a thousand subtle environmental messages that allow them to germinate at just the right time. If conditions are right in spring of 2023, those seeds will send small leaves toward the sun. If conditions don’t align for growth, these seeds will bide their time until a future spring. 

The benefits for those hoping to restore landscapes with native seed is that dollars spent on seed, when it is planted at the right time and with good attention to site preparation, is rarely wasted. Even if only half of the species placed in these demonstration sites as seed develop into mature plants, the result will be higher species diversity than if we had relied only on planting starts or plugs available from native plant nurseries. And, at $14/oz* of seed versus $2-$20 per individual plant plug, our restoration dollars are stretched further. 

Stay tuned for the next blog post in which we’ll reveal our monitoring results and lessons learned from this project.

The Seed People: Reflections on the 2023 National Native Seed Conference

Posted on by Tuula Rebhahn

In the midst of Cherry Blossom Madness in Washington, DC, a contingent of Oregonians landed to be among “our people”: Seed (but never seedy!) People.

The theme of the 2023 National Native Seed Conference was “Cultivating the Restoration Supply Chain”. In the past few years, we’ve all become all too familiar with the term “supply chain” in the context of supply shortages. In the restoration world, the supply chain doesn’t just involve farmers, distributors, native seed partnerships and administrators, though all of these people are important. The most important “people” involved in habitat restoration are plants – the source of all those vital genetic information packages that we know as seeds.

Best practices in habitat restoration say to use locally genetically adapted seed for revegetation of degraded landscapes; however, in many parts of the US and the world, locally adapted seed is simply not available, or it is so scarce as to be unaffordable. The National Native Seed Conference (NNSC) convened to clearly define the barriers to building a more abundant native seed supply chain, and to explore some possible solutions.

Rogue Native Plant Partnership was able to participate in this conference thanks to the generosity of the Institute for Applied Ecology (IAE), who sponsored Tuula Rebhahn and Vanessa Robertson-Rojas to attend. Funding from RNPP partners Confederated Tribes of the Siletz Indians sent a third delegate, Kathryn Prive. Tuula and Kathryn coordinate the RNPP through its fiscal sponsor, The Understory Initiative, and Vanessa is an Ecologist with The Understory Initiative who manages several native seed farming contracts in the Rogue Basin.

Safe from crowds of selfie-taking tourists in a conference hotel just downriver from our nation’s capital, the three of us, along with 500 other conference attendees, were treated to a blossoming show of a different sort. A gorgeous diversity of flower photos accompanied many charts and graphs compiled by researchers, farmers and restoration practitioners, magnified by powerpoint projections. For three days we took in dozens of rapid-fire presentations to learn about all aspects of the seed supply chain. With partners at IAE and US Fish & Wildlife Service, we also facilitated a symposium on Oregon’s native seed partnerships, and Vanessa presented research by The Understory Initiative into the efficacy of planting natives beneath solar panels (a recording of the symposium presentation will be available soon and shared via the RNPP Newsletter).

Needless to say, we learned a lot, and the value of putting faces to names, and bodies to floating heads on the Zoom calls of the past three years, is immeasurable. To distill all of the information, insights and “ah-ha!”s into a neat written package is probably a fools’ errand, but we would like to try anyway.

Here are our takeaways from NNSC2023.

1. We Are Not Alone

Native Seed Conference Attendees tour the US Botanical Garden in Washington, DC. Representatives from Oregon, Iowa, Utah, California, Connecticut and Hawaii!

There’s probably not a single person who hasn’t felt a sense of laboring in isolation over the past three years, whether physically or conceptually. But in the process of preparing for the conference and in the days we spent networking, we recognized that Seed People are everywhere – in Oregon, across the US, and even globally. We counted eight partnership-type groups in Oregon that coordinate native seed production, distribution and application in our state alone. Seed partnerships are “sprouting up” in the northeastern US, Arizona, Nevada, California, Iowa, Wyoming and Hawaii. We even talked to a seed farmer from Germany. In all of these groups, we heard about similar challenges: 1. Convincing farmers that growing native seed is financially viable; 2. Finding reliable sources of information about how to grow native plants that are not commercially produced; and 3. Sourcing the foundation seed from the wild in areas where there are precious few intact native plant communities left.

One of the most fascinating parts of the conference was hearing from large native seed growers who are producing acres of seed on an industrial scale, in places like California’s Central Valley and in the fertile Midwest. According to one presenter, who cited public USDA farm data, there are more than 650 entities growing native seeds in the US. The USDA also lists over 35,000 acres dedicated to the production of native grass seed, and 10,000 acres producing forbs. The native seed farmers on this panel were confident that they could grow out just about any species of seed, if given enough time to understand how to grow it on a large scale. Using tractors, herbicide, armies of seasonal labor, and huge refrigerated storage facilities, they promised “all the seed you can use and more”.

Let’s come back to that after we return to the world of plants for a moment.

2. Smaller is Better

In the opening plenary, Dr. Tom Kaye from the Institute for Applied Ecology shared research showing that biodiversity is essential not just for plant communities, and the web of life that depends on plants, but also for human health and well being. He cited studies showing that the microbiome that coexists with and supports a diverse set of floral life contributes to a more diverse microbiome for humans. This may have positive impacts for everything from immunity and digestion to general mood.

Diversity is crucial because it allows plants – and every other life form – to adapt to changing conditions. On the final morning of the conference, Elizabeth Leger from the University of Nevada presented research from her lab showing that smaller bunchgrasses are better adapted to survive hot, dry conditions, and may even compete better with invasive cheatgrass. While bigger is usually assumed to be better, and certainly has its advantages for plants in many contexts, it was the plants genetically predisposed to smallness that avoided shriveling in the desert sun and held space against a smothering competitor. If the genetics for “smallness” did not exist in these fescues, they might not exist today in the hottest, and most heavily invaded regions of their habitat.

Small has its advantages for trees as well. Another study presented by Erin Baumgart of the US Forest Service showed that Oregon white oak trees subjected to “plant torture” (grown in small pots, pruned to the base after the first year of growth) actually performed just as well or better under drought conditions than trees allowed to reach their maximum size in the same time period.

We would argue that producing plants and seeds on a small scale, in the same bioregions where they adapted and where they will be replanted, makes good ecological sense as well. Though we see a time and a place for large-scale production of seeds at large farms in fertile agricultural region, there are reasons that local food advocates have been calling for de-centralization and de-industrialization of agriculture for fifty years or more. We saw how fragile the supply chain is during the pandemic and extreme weather events of late. And we also believe in the tremendous potential of the native seed economy to transform struggling rural communities, many of which need to transition to non water-intensive crops in the very near future. Small is better.  

3. Climate change is now, let’s adapt

Plants are one of the best defenses against the hazards posed by climate change – they stabilize soils and streambanks, shade the earth, and shelter and provide food for vulnerable life-forms from butterflies to people. Study after study has shown that the impacts of climate change are happening today: Increased frequency and intensity of fires, peak summer temperatures that are hotter and last longer than before, and more erratic weather patterns overall.

We also know that every plant has its “zone” of ideal conditions. They are adapted to thrive in the particular climate, soil type and elevation where they evolved. What we don’t know is how flexible they can be when climate conditions veer into the extremes, especially at the rapid pace at which the climate is changing (an estimated 10x faster than the pace of evolution). Waiting to “see what happens” could mean allowing millions of plant communities to expire before they can adapt.

Many of the NNSC presentations echoed a clear call to action: Assisted migration. Plants need outside help to move into the new climate reality, and who better – with our hands, feet, trucks and seed-drills – than humans to take on the task?

To take on this unprecedented task, there is no agreed-upon set of protocols. But even though the problem is not well studied and models are unreliable, there are some tools that can point us in the right direction.

Tom Kaye highlighted the “Climate-Adapted Seed Selection Tool” which can be useful for identifying species and ecotypes (local, genetically distinct populations of species) to use in restoration and revegetation projects. This tool allows the user to input a broad range of climate variables to obtain an output of where to source seeds that might be “climate adapted”. If unsure which variables to select, Dr. Kaye recommends increasing the winter minimum temperature and lengthening the summer drought period, two factors that have been shown to have an impact on plant germination and long-term success.

In addition, Dr. Kaye advocated for “adapting sourcing”, or choosing seeds from species and ecotypes that fall within a Venn diagram spanning three categories. First, locally adapted seeds. Next, locally adapted seeds that come from populations that have experienced “bad” years (eg. drought) or that eke out a living on harsher sites within the local area. Finally, seeds should be sourced from areas outside the locality that have been identified as climate analog zones. These are areas that models predict will have similar weather to your area in the future. For example some have estimated that the Rogue Basin area may look more like Chico, California in 30 years.

Will adaptive sourcing be enough to preserve plant communities into the future? We heard from another presenter, Jack Zinnen from the University of Illinois, that species diversity is another crucial part of the puzzle. Getting a wider diversity of species into the restoration supply chain is challenging – though plants that are easy to grow and harvest like grasses, trees and showy, generalist forbs are widely available (not as available as lettuce seeds or red maple seedlings, but available in the context of native plants), a large number of genera are not being grown out in farms. These include sedges, anything that is “weedy” (prone to take over agricultural fields) and ugly, late successional plants (which are not often used in restoration projects) and plants with complicated life cycles (which take a long time to produce a marketable product). This is not the fault of farmers (who must pay their bills and feed their families off of these unpredictable and unwieldy plants); those who value ecological diversity are also tasked with making it economically viable.

It’s not a small task; none of this work will be easy. But we returned from the conference emboldened and inspired all the same. We are dealing with tenacious, surprising plants, and creative, hardworking people. We may be small, but we are not alone, and we will adapt.

Another big thanks to IAE for organizing the National Native Seed Conference; we hope to see you there next time.

Native Seeds in Restoration: Garlic Mustard Part 1 – Project Overview

Posted on by Tuula Rebhahn

One of the most challenging aspects of controlling invasive plants is that even when treatments are successful, a healthy, diverse community of native plants does not usually spring back to replace invasives. Most invasives require many years of targeted treatments to eliminate them from a site, and garlic mustard is a particularly challenging one. Meanwhile, native plant communities can all but disappear from the site over years of being sprayed with herbicides and suppressed by the invasive plant itself.

Garlic mustard (Alliaria petiolata) invades riparian woodlands in the western US, and was first introduced by settlers who enjoyed its leaves for food (another common name is “poor man’s mustard”). Garlic mustard has been present in the Rogue Basin for at least a decade, and treatment efforts have focused on using herbicides to limit its spread. However, no focused research has been done to understand the best way to restore native habitat after treatment. 

In summer of 2022 Rogue Native Plant Partnership launched an exciting new collaboration with the Jackson/Josephine County Cooperative Weed Management Area (CWMA) and Oregon Department of Agriculture (ODA) to work on this problem. We’ll be creating two demonstration sites to attempt to re-establish a native plant community after years of herbicide treatment, using a seed mix developed for Rogue River riparian habitats. In a series of three blog posts we’ll describe our methods, and the results. But first, a little background about garlic mustard!

Garlic Mustard: More than just bad breath

Though it is widespread in the northern Willamette Valley, garlic mustard has a limited presence (net treatment area less than 100 acres) in the Rogue Basin. When allowed to overtake forest understories, garlic mustard greatly reduces the availability of native plants that are vital to wildlife, including deer, elk and pollinators (ODA, 2015). Its large, broad leaves effectively shade out all competing vegetation. To add to this, the plant also emits a compound that prevents the seeds of native plants from germinating (a strategy known as allelopathy) (Prati, 2004).

A “Clean Slate”

Garlic mustard was first discovered along the Rogue in 2010, and the plant has been the target of treatment efforts since then. Two treated sites are now the focus of the RNPP re-seeding project. They are less than three miles apart on opposite banks of the Rogue River, located between the cities of Gold Hill and Central Point, Oregon. One is a privately owned ranchette along John Day Road and the other is on Oregon Department of Fish & Wildlife lands. For consistency, we will refer to these sites as “John Day Rd. site” and “ODFW site.”

At the ODFW site, garlic mustard was first reported around 2012 and herbicide treatment began soon after. Herbicides used were broad-spectrum and sprayed widely, resulting in the total suppression of all new growth of plants including trees and shrubs. In 2017, the strategy evolved to spot treatments with herbicides specific to forbs, so that grasses could regrow at the site. The grasses did rebound but were non-native. Some small areas were seeded with native grasses in an attempt to add species diversity. 

At the John Day Rd. site, the treatment history is much shorter. After the landowner removed blackberry near the river a few years back, garlic mustard “exploded” at the site. Herbicide treatment began in 2022, and as is the current practice at the ODFW site, only forb-specific herbicides are used in a spot-treatment method.

Despite the differences in treatment history, both sites looked pretty similar vegetation-wise when the RNPP contingent arrived in the fall of 2022 to plan our reseeding strategy. Under a shady canopy of mature bigleaf maple, Oregon ash and cottonwood was a nearly “clean slate” of rich, brown streambank soil, hardly a green leaf in site. However, we know that seeds of both garlic mustard and native plants are lying dormant in the soil. Our hope is that by adding native plant seeds in a targeted way, and continuing to spot-spray emerging garlic mustard, we can give native plants the advantage.

Why Seeds?

Why use seed for habitat restoration and not established plants? Reseeding is used as a restoration strategy because it is less expensive than planting containerized plants, requires little or no irrigation, takes less labor and is more realistic on large scales. Although it can take longer for plants starting from seed to reach maturity and “hold space” against invasive weeds, seeding mimics the natural regeneration process (existing native plants dropping seeds on the ground) and allows for more species diversity than restoration methods that rely on nursery stock.

In the next blog post, we’ll reveal which native plants were included in the seed mix for the project, and how they were chosen. We’ll also get into the nitty gritty on designing the layout, prepping the site, and making divots! 

Meanwhile we’d like to thank Rogue Basin Partnership for being the umbrella organization for the CWMA and so much more, including connecting RNPP with this opportunity to get native seeds on the landscape. In addition, Chris Pirosko of Silver Fox Pond & Lake Management and Kyle Strauss of Strauss Ecological Services provided highly useful intel on garlic mustard and are out there doing the hard work of invasive plant control all year ‘round.

Emergency Pollinator Funds in the Pipeline: Native Plants Needed!

Posted on by Tuula Rebhahn

“There are now more Starbucks in California than monarch butterflies.” This simple statement from the Center for Biological Diversity sums up a dark forecast for this iconic pollinator.

Monarchs depend on milkweed flowers.

Western monarchs have declined by over 99.9% since the 1980s, with just under 2,000 migrating individuals found at the most recent count in late 2020. Other pollinators, too, are threatened: The Western Bumble Bee has declined 90% in the past two decades, and butterflies like the Mardon Skipper and the Oregon Branded Skipper are known to only exist in isolated and shrinking populations, according to the Oregon Biodiversity Information Center.

Federal lawmakers are stepping in to address this issue by making funds available for habitat improvement and conservation projects across the West, and specifically places like the Klamath-Siskiyous, where species endemism is high.

Two major pieces of legislation have been introduced in Congress which, if passed, could provide a major influx of cash to support habitat restoration in our region. One is the Monarch Action, Recovery, and Conservation of Habitat Act (MONARCH Act) of 2021, which would authorize $62.5 million for western monarch conservation projects, and another $62.5 million to implement the Western Monarch Butterfly Conservation Plan, paid out over the next five years.

This plan, developed by US Fish & Wildlife, calls for habitat restoration with a focus on native plants that provide food and habitat for monarchs and other pollinators.

The second piece of legislation is the Monarchs & Pollinators Highway Act. This act would earmark $35 million in funding to go toward pollinator-friendly projects on roadsides and highway rights-of-way. The Oregon Department of Transportation and local Native American tribes would be eligible to apply for these grants. (ODOT as well as several tribal groups already participate in the Rogue Native Plant Partnership.)

Both the MONARCH and the Monarchs & Pollinators Highway Act are seeing solid support by legislators, and our local offices of the US Fish & Wildlife Service are encouraging partners to develop “shovel-ready” projects that can be implemented if or when these funds become available, which could be as early as fall 2021. Altogether about $55 million per year in funding could be released if the bills go through.

What’s a “shovel-ready” project? One that puts native plants in the ground now so that pollinators can access them this time next year. The underlying message here is that we need more native plants. Restoration practitioners will be looking for containerized plants for their projects, as well as native grass and wildflower seeds that can be direct sown. To meet the potential demand for native plant materials in the coming years, local growers will need to scale up their production. Seeds will need to be increased in grow-out operations over multiple acres, and many hours of work will go into turning those seeds into habitat.

For the monarchs and other fascinating, beautiful and ecologically critical pollinators, we think it will be worth the effort.

Fiddleneck Going Gangbusters? Here’s what to do with it…

Posted on by Tuula Rebhahn

Common Fiddleneck (Amsinkia menziesii) is a fun yellow flower with a long, gradually unfurling bloom that resembles the top of a fiddle. Although it is native all across the western US and is good at colonizing dry, disturbed areas, we don’t see it too often here in the Rogue Valley! That’s too bad because it’s classified as a valuable resource for pollinators by the Xerces Society, and it’s a self-seeder and easy to grow.

Photo by Tracy Bandy: https://www.inaturalist.org/people/tracybandy

2021 seems to have been an extra-great year for Amsinkia. RNPP member Michelle wrote us this spring to say “The bloom is off the charts this year!”

Do you have Amsinkia growing nearby that you’d like to harvest? The seeds of this wildflower are abundant and easy to collect. Just as the blooming flowers progress up the stem (starting at the bottom), so do the ripening seeds. At this point in the year, the seeds from the bottom will have already dropped off, ensuring regeneration of this annual plant next year. Now’s the time to come by and collect the rest of the seeds for sowing elsewhere!

Here are more tips for harvesting Fiddleneck seeds:

  • Amsinkia produces 4 nutlets per flower (see photo).
  • Harvest the nutlets when they are ripe – brown in color and not easily dented with a thumbnail.
  • Be sure to leave some seeds on the plant to ensure that the patch will regenerate next year!
  • To harvest the most possible seed from individual plants, cut or snap the plants off at the base when about half of the nutlets are ripe. (Remember to leave the majority of plants where you find them so that they can do their thing!)
  • Lay the plants out on a tarp in the sun for a few days to let the rest of the seeds ripen.
  • Once the plants are pretty dry, grab a handful of stems (with gloves to avoid the sharp hairs) and bang the bundle against the inside of a large rubber storage tub to break loose the seeds.

Native Plant of the Month: Fawn Lilies

Posted on by Tuula Rebhahn

Fawn lilies (Erythronium genus) are a sure sign that spring has arrived in Pacific Northwest, and we have a couple of special local species that only occur here in the Klamath Siskiyous: Erythronium klamathenses and howellii.

On the shady forest floor, fawn lilies might not grow taller than your hiking boot, but coming across a large patch of them in late March to early May is a delightful surprise. You might need to get your chin to the earth to appreciate the delicate beauty of these downward-facing blossoms!

Erythronium grow from bulbs, a source of sugar that allows them to bloom earlier in the year than other wildflowers. Although they can produce additional bulbs to grow their numbers, the primary way in which they spread is by seed. So, it’s extra important not to pick these lovely forest friends, so that they can come back with reinforcements next year!

How to Find Native Plants in 2021

Posted on by Tuula Rebhahn

Rogue Native Plant Partnership seeks to bring together native plant (and seed) growers with people who need native plant materials for landscaping and habitat restoration. One way we typically do this is through a native plant sale in the spring, but this year, the growers we normally work with simply did not have enough plants on hand to justify holding a sale!

However, that doesn’t mean there aren’t any native plants available in the Rogue Basin. We put together this list so that those seeking plants this spring (or any time of year) can hopefully find what they’re looking for.

1. Go to a pop-up sale

These events are typically hosted by non-profit groups or small farms with roadside stands. Two RNPP members hold pop-up sales every year: Pollinator Project Rogue Valley and Jackson County Master Gardeners.

Pollinator Project Rogue Valley  – Sale April 25!

This educational nonprofit holds outdoor plant sales in the spring and fall. With a focus on native pollinators, plants are from local growers or grown on site from seed from their demonstration garden.

This April 25th, they are hosting their second annual Native Plants for the Pollinators sale April 25th. Suzie Savoie of Klamath Siskiyou Native Seeds is the featured vendor, with additional plants available from PPRV.
A preliminary list of plants that will be available at the sale will be posted on the Facebook Event page by April 5th.
COVID-19 safety protocols will be in place, including timed shopping. Go to the Eventbrite to register for the hour that you plan to shop.

January Native Plant of the Month: Lemmon’s needlegrass

Posted on by Tuula Rebhahn

Winter is when native bunchgrasses shine. After other understory plants lose their leaves and flowers, perennial bunchgrasses such as Lemmon’s needlegrass flare out from the earth while extending their root systems deep underground.

Lemmon’s needlegrass (Achnatherum lemmonii), bears long, needle-like awns extending from either side of the seed, a feature which can make this plant unpalatable to livestock. However, birds and small mammals have no problem plucking the nutritious seed from between the awns. Deer and elk also browse on Lemmon’s needlegrass, while moths and butterflies nest at the base, making this a key species for wildlife.

This attractive bunchgrass is popular as both a landscaping plant and in habitat restoration. It needs little maintenance once established and stays green late into the summer. It is an essential component of oak savannah and prairie habitat and, as shown in the photo, resprouts readily after a burn. There is even a local subspecies, Achnatherum lemmonii subsp. pubescens, that is adapted to serpentine soils.

Rogue Native Plant Partnership: 2020 Was No Match

Posted on by Tuula Rebhahn

Between moving to a dedicated seed storage facility, adapting to COVID and an unprecedented wildfire season, and stepping back to plan for the next five years, it’s been an eventful year for the Rogue Native Plant Partnership! Despite the challenges of the year, our partners have remained committed to the cause and the support from the community has been terrific. Read on for some highlights and photos from the past 12 months!

Volunteers collecting native grass seed at the Rogue River Preserve in July 2020

Big Year for Volunteers – Thank You!

In masks and with mobile hand washing stations, volunteers showed up in force this year to collect seed and put native plant plugs in the ground. RNPP held a number of successful events, including:

  • Two seed collection events, or “seed blitzes”. The first was held in June at BLM’s French Flat site near Cave Junction. Volunteers collected wildflower seeds like selfheal (Prunella vulgaris) and California oatgrass (Danothonia californica) that are uniquely adapted to grow on the serpentine soils at this site. 
  • A July seed blitz at Rogue River Preserve, where volunteers gathered seeds from the delightful wooly-headed clover (Trifolium eriocephalum) as well as four other native forbs and grasses.
  • Two planting days held in partnership with the BLM at Upper Table Rocks – one in early spring and one just a few weeks ago in December. With several volunteers and a handful of BLM botanists leading small teams, we hiked out to sites where burn piles from brush thinning had left lovely ash piles (with gorgeous views of Mt. McLaughlin). Between the two events, over 150 native grass and forb plugs were put in the ground to enhance the native oak savannah habitat. 
  • Several milkweed pod collection events at J. Herbert Stone nursery this late summer and fall. Braving the smoke and heat, intrepid volunteers collected hundreds of pounds of pods, which will be tumbled and cleaned to separate the milkweed seeds from fluff, and used for plantings that will support our migratory monarchs and other pollinator species.

Woody Species for Fire Response

In 2019, an RNPP subcommittee was formed to create a short list of “most wanted” woody plant species (shrubs and trees), which are highly desirable for restoration projects but difficult to source locally. It was decided that contracting with an expert botanical collector would be the best way to obtain these seeds, and in fall of 2020 we had our first delivery of seeds from Siskiyou Biosurvey. 

Prunus virginiana seed
Chokecherry (Prunus virginiana) was one of the species collected through this initiative, and is currently being grown out so that this fast-growing riparian tree may be used in restoration work.

Acting quickly, we were able get these seeds cleaned and turned around and sold to growers, so that they can be grown out over the winter and spring to become viable plants that will be used for restoration. After the fires that ripped through the Rogue Valley in September, growers and nurseries are expecting an unprecedented demand for shrub and tree plugs.

Plant and Seed Sales

A big part of the Partnership mission is to get native plants in the hands of restoration practitioners, and this year we were able to sell seeds, plugs and containerized native plant starts. 

Organizing plants for distribution to buyers throughout the Rogue Basin.
  • Our annual native plant sale happened in spring, with online ordering and drive-through pickup in Ashland and Cave Junction. With 33 different species available from a variety of local growers, it was quite the coordination effort, but in the end the right plants ended up in the right hands! We had assistance with the sale from Vesper Meadow Education Program and Illinois Valley Soil and Water Conservation District, so a huge thanks to them for helping make it a success.
  • After several years of wild collecting seeds, we were finally able to offer a sufficient quantity and diversity of native seeds to hold a sale! It was held in fall in the same format as the plant sale. In order to ensure that these precious seeds would be put to good use, we asked for a restoration plan from all our buyers. Many pounds of seeds were distributed through the sale to a variety of buyers, from government agencies to individual landowners. The Freshwater Trust and others were able to immediately plant seeds in burned zones this fall, one silver lining of the devastating fires. Overall, we judged our first seed sale a success, and its proceeds will be used to coordinate future seed collection events and to pay for the required seed cleaning and testing.
Bags of hand-harvested native seed are labeled, inventoried and stored in dedicated freezers at the Selberg Institute facility.

Coordinating Seed Production

Our achievements this year also comprise a handful of small “wins” that will streamline the process of collecting, cleaning and redistributing native seeds for years to come.

  • Completion of our comprehensive regional Species Priority list, which will guide the work to be done in seed collection and plug production going forward.
  • Moving all our seed cleaning and storage equipment to the space at the Selberg Institute, south of Ashland. It has worked wonders to have a dedicated, secure space to use year-round to organize, store and clean seeds.
  • Training partners on the use of the seed cleaning equipment, including local seed growers and members of the Yurok tribe.
  • Documenting our seed cleaning methods so that others can learn from our hard-won lessons! (Did you know that elderberries should be fermented to separate the seeds from the berries?)
  • Expanding our online resource library and blog to make access to the latest research and literature on ecological restoration accessible to all. 
  • Assisting Oregon Department of Transportation with organizing their seed inventory, so that the right seeds can be used in the right locations (and excess seeds can be directed to post-fire restoration).
  • Completion of our Five Year Strategic Plan, providing direction and goals for 2021-26. We’ll recap this plan in an upcoming blog post.

Facilitating Conversations about Native Plant Restoration

This year, we held two general Partnership meetings, and both were conducted remotely, with 25-30 people attending each meeting. 

  • In March, we heard from Joshua Chenowith, whose role with the Yurok tribe puts him in the position of procuring native plant materials for use in restoration of the Klamath dam site.
  • At our December meeting, our guest speaker was Chris Adlam, Regional Fire Specialist at OSU Extension. His talk about the role of native plants in fire behavior sparked some great discussion. Read our recap here. 
  • Notes from both of the 2020 General Meetings can be found here.

In addition to the General Meetings, we also held various subcommittee meetings to work on a riparian seed mix for post-fire restoration, plan for the future of RNPP, and continue to refine our priorities.

We look forward to another year of working together to bring more native plants to our wonderful Rogue Basin. Stay in touch and all the best in 2021!

December Plant of the Month: Common Yarrow (Achillea millefolium)

Posted on by Maggie

Common Yarrow (Achillea millefolium) is a common perennial herb known for its fragrant leaves and healing properties. This widespread plant is found throughout the Pacific Northwest and the Northern Hemisphere. Yarrow thrives at a variety of elevations, in both wet and dry climates. In Southern Oregon, you might see yarrow in open grasslands, forests, or maybe even in the corner of your lawn. 

You might be familiar with yarrow’s summer appearance: a wide cluster of flowers rising from a base of green, feather-like leaves. In winter, yarrow looks quite different. The stalk and flowers dry out, turning a dark brown color. Small pockets of seeds are left where the flowers used to be. Often you’ll still see the green, feathery leaves along the base of the plant, ready to grow again come spring. 

Yarrow has been used medicinally for millenia. Leaves were commonly crushed and used as an astringent for wounds (to stop bleeding). Dried yarrow was made into a tea and used to cure digestive, respiratory ailments. The plant is also well loved by pollinating insects and a variety of wildlife!

Native Plants Under Fire: RNPP December 2020 General Meeting Recap, Part 1

Posted on by Tuula Rebhahn

Blame it on 2020 – our attempt to record the General Meeting on December 8th was not successful. Fortunately, we were able to take good written notes, so in this blog post we’ll summarize the fascinating and important presentation by Chris Adlam on what happened in the Almeda fire, and his ideas for improving community fire resilience using native plants. We also have thrown in a few slides from the presentation, and a link to all the slides at the end of the post.

Keep an eye out for the next RNPP blog post, where we will catch you up with the Rogue Native Plant Partnership updates, and our achievements in 2020.

Urban Fire in the Rogue Valley: Are Native Plants the Solution? 

Christopher Adlam may be new to the Rogue Valley, but having lived and studied in northern California, he may understand our fire future better than most! Chris recently joined the OSU Extension team as Southwest Oregon’s Regional Fire Specialist, and he holds his PhD in Ecology from UC Davis. He has studied the effects of fire on plant and animal diversity, as well as community fire resilience. So who better to bring in for Rogue Native Plant Partnership’s guest speaker for our late-fall General Meeting? 

As he launched his slideshow, Chris wisely noted that this is a difficult subject for many, and we echo the sentiment that it’s not easy to talk about the science behind something that affected this community in such deep and diverse ways. However, we feel it is necessary to take a step back, and use our best methods of analysis to look at what happened. Like detectives, we can trace the path of the fire and see what it tells us about how to protect our communities the next time around. Though many homes and businesses were lost, the Almeda Fire could have been much, much worse. There are no simple explanations as to why the fire spread or failed to spread to certain areas of the valley, but we do know that vegetation – both native and invasive plants – played a role in both. 

The Almeda fire started in Ashland on September 8th, 2020, and driven by strong winds, swept into the Bear Creek Greenway, where it burned through riparian zones, grassland, oak savannah and pear orchards before moving on to become an urban fire around Talent. When the fire left the greenway, and we saw houses burning other houses in a chain reaction.

Did the Greenway’s plants and trees, dry after a long, hot summer, cause homes to burn? Chris asks us to back up a minute before answering this question. When people think about the relationship between vegetation and structures, they either fall into the “liability model” camp or the “green solutions” camp. The “liability model” says that the real risk of wildfire is in wildlands, and that plants are setting homes on fire, making plants a liability. Under this model, people move into the wildland urban interface and cut down all the trees around their home in the name of fire safety. 

The “green solutions” perspective, on the other hand, embraces the ability of healthy natural areas and vegetation to actually moderate the risk of fire. For example, plants can moderate fires by slowing their spread, slowing down wind speeds, and catching embers that would otherwise end up on someone’s roof. 

Structures catch fire in three ways: Radiant heat, direct flame contact and embers. In the case of the Almeda fire, few structures had enough vegetation nearby to generate the amount of radiant heat or direct flame contact necessary to ignite a home. So, we can rule out the first two causes of structure fires in this event, which leaves embers as the sole remaining culprit. In fact, embers are the cause of most home fires that spread from wildlands; they can travel for miles to land on homes, work their way through roofing or siding material, and burn the home from the inside out. After that, radiant heat coming from other homes was the main method of fire spread in the urban Almeda fire. 

Were embers generated by vegetation in the Greenway? Absolutely, and we are looking at one plant in particular that burns explosively, sending tall flames and embers into the air: Blackberry. 

Image of blackberry plant on fire.

Restored Areas Burn Slower

Almost immediately after the Almeda fire swept through our region, we heard from restoration practitioners about the profound differences in the impacts of fire on restored vs. non-restored areas. In areas that were restored with native plants, with no blackberry surrounding and climbing up the trunks of trees, the fire burned as fire naturally would in a riparian zone: low and slow. It top-burned understory grasses and native shrubs, without frying the soil, and without climbing into the canopy of large established trees. As a result, these trees survived the fire, and understory shrubs are already resprouting with new growth. 

Example of how the Almeda fire affected restored areas along Wagner Creek in Talent (low, slow, understory burn).

In areas that weren’t restored (most of the 300+ acres of the Bear Creek Greenway), where thickets of blackberry formed a thick blanket over the riparian zone, we saw high intensity fire that destroyed all understory vegetation (except for the hardy blackberry roots) and most of the large trees as well.

Yes, Chris agreed, removing blackberry and replacing it with native shrubs will definitely reduce fire risk. But there’s more that native vegetation can do to improve fire resiliency in our community, and it doesn’t need to be limited to the riparian zone.

Trees to the rescue?

Next, the discussion turned to potential strategies for putting native plants to work to improve our community’s fire resilience. Many native plants in our ecoregion are fire-adapted, meaning that they can resprout quickly after a burn, and thrive from the nutrients created by burned dead material. Some plants even need fire to reproduce, while others grow more fire resistant with age. For example, Ponderosa pine trees, though highly flammable when young, are fire-resistant when mature, with thick bark that deflects heat and embers. 

One aspect of the behavior of the Almeda fire that we found interesting was the effect of “shelterbelts” of trees that were able to shield homes from fire. Deciduous trees like cottonwoods, or even mature conifers, when planted together, formed a “curtain” of vegetation that may have caught embers and let them fall to the ground, where they can extinguish themselves. This effect has been documented in Australia, where shelterbelts are commonly planted as windbreaks. Looking at images of these landscapes after a fire, homes behind shelterbelts were spared. Chris emphasized that this effect has only been observed anecdotally, but it deserves further study. 

Expanding on the shelterbelt concept to shield homes, to shield entire communities from strong winds like we saw the day of the Almeda fire, is another possibility. Traditionally, the hillsides surrounding Ashland up to Medford have been populated by oaks and madrones; could these trees function as valley-wide shelterbelts to slow down windspeeds and capture embers traveling from afar?

Who’s burning who?

After the slideshow, Chris fielded many questions from the audience, but we’d like to circle back to a question about the fears some members of the community have about vegetation in the wake of the fire. Falling back into the “liability model” of structure-vegetation interactions, some (not in this audience, but members of the community at large) are suggesting or considering clearing all trees and shrubs from properties to improve fire resistance. 

Says Chris, “Your neighbor’s house has a higher likelihood of burning down your house than your vegetation does.” Yes, he says, if leaves and needles from nearby trees are covering the roof and filling the gutters, that would be a factor in setting a house on fire. But generally, the advice is to keep all vegetation cut back 5’ from homes, and to thin vegetation within 100’ of the home. (Read more about thinning recommendations from the NFPA.) This should be enough to prevent flames from a vegetative fire from spreading to a home. In fact, it’s possible to see situations where the house initially caught fire from an ember, and downwind trees were burned or scorched, but upwind trees suffered no damage. In other words, it’s not the trees lighting the houses on fire, but the other way around. The solution is to construct more fire resilient homes, which is already possible and not more expensive that traditional construction methods.

Revisioning the Greenway

Some audience questions focused on the actions we can take next to improve fire resilience in our community while promoting the use of native plants in restoration efforts. 

To that end, Rogue Native Plant Partnership has formed a working group to develop a native seed mix appropriate for reseeding riparian zones. Although the initial seeding of the Bear Creek Greenway has already taken place, it could be possible to include native grasses and wildflowers in future re-seedings. These species will provide benefits to wildlife while staying green later into the summer, reducing the flammability of these areas. 

Meanwhile, we support all efforts to suppress blackberry re-growth until native plants can be established. Agencies and local governments are seeking funding for restoration work, and there’s some talk of a community visioning process to begin next year, to receive public input into how to manage the Greenway going forward. Participation of native plant enthusiasts and restoration practitioners will be vital, to identify and question “liability model” thinking. We don’t need to, nor should we eliminate all vegetation in fire-prone areas, but focus on evidenced-based solutions that work.

How To Find Your Soil Type

Posted on by Tuula Rebhahn

An important component of any habitat restoration plan is the soil type. Knowing what types of soil are present on the property will help you decide which plants will do best in each location. When it comes to healthy plants, having the right soil conditions is about as important as siting the plant correctly for optimal sunlight (shade or full sun?) and water (dry or moist?).

Fortunately, the USDA’s Web Soil Survey exists to impart data already collected by the USDA to members of the public. It’s as easy as going to the website and entering your address (plus a couple extra steps). Let’s walk through it together:

How to Get Your USDA Soil Report

  1. Navigate to https://websoilsurvey.sc.egov.usda.gov/App/HomePage.htm
  2. In the drop-down Address field on the left, enter your address.
  3. Use the AOI button in the “Area of Interest (AOI)” tab to select the area for which you would like the soil information.
The Area of Interest is selected
  1. Once you’ve selected your Area of Interest, click the yellow Soil Map tab. Click “Printable version” in the upper-right corner to save or print this map.
Soil map of the Area of Interest
  1. Now, click the “Soil data Explorer” tab, then click the “Soil Reports” tab in the ribbon below. On the left-hand menu, click the drop-down arrows for “AOI Inventory”, then “Component Text Descriptions”. Then click “View Soil Report”. A description of each of your soil components will appear below the map.

November Native Plant of the Month: Licorice Fern

Posted on by Maggie

RNPP has a Native Plant of the Month column in the Rogue Basin Partnership newsletter! You can find the full RBP November newsletter here, and our Native Plant of the Month Column copied below.

As the reds and yellows of fall begin to fade, my eyes are drawn from the canopy to the forest floor, where spots of green create a vibrant contrast with the fallen leaves. Licorice fern (Polypodium glycyrrhiza) is a common fern found in mixed conifer and deciduous woodlands, thriving in moist, shaded to partly-shaded environments. It is native from Southern Alaska to California, with isolated populations existing in Idaho and Arizona.

Licorice fern often grows on the mossy trunks and branches of deciduous trees, but can also be found on mossy rocks, logs, or the forest floor. Fronds have simple pinnae with pointed tips, and often swoop downward from their perch on tree trunks and branches. Licorice fern is named for its rhizomes, which taste of licorice. These rhizomes were used medicinally by Native Americans as a remedy for coughs, colds, and sore throats.

Seeding Your Site: Methods, Rates and More!

Posted on by Tuula Rebhahn

So far in our Restoration Best Practices blog post series, we’ve covered Developing an Ecological Restoration Plan and Site Preparation, which is particularly important if you’re planning to use native seeds to restore your site. Whether it’s a prairie, wetland, forest or another type of ecosystem, the survival and success of your native seeds is entirely dependent on having low competition from non-native plants and nice, loose soil in which to put down roots. We encourage you to go back and read those two posts if you haven’t yet. (Remember, a Restoration Plan is required if you are buying seeds from RNPP this fall!)

In this blog post, we’ll discuss some of the reasons for using native seeds vs starts and how to choose seeds for your site. Then we’ll move into some of the technical details of creating a seed mix and introduce our calculator tool for figuring out how much seed to buy. 

Why Seeds?

Growing plants from seed is more work than buying plants already established in containers. So why do it? Here are a few reasons:

  • Diversity. Here in the Rogue Valley, growing from seed gives you a much wider array of species to choose from. Not all plants are going to be available in containers.
  • Success. Some plants don’t survive transplanting very well, and plants actually have the remarkable ability to adapt to a site as they grow. So, the moment a plant puts down roots in your soil, it is learning about the local conditions and setting itself up for faster, stronger, healthier growth.
  • $avings. It’s much cheaper to grow a thousand plants yourself from seed, than buy all those plants in containers!
  • Fun. You’ll learn much more about the native plant life cycle by watching them grow from seed. There’s nothing like seeding a site in fall, then coming back in the spring and seeing the brown earth covered in green!

Selecting Your Seeds

In restoration work, it can often be difficult to decide what kind of plant community to establish, especially in sites long dominated by non-native species. It’s important not only to look toward the past, understanding what plants might have grown in your site (perhaps prior to the disturbance that caused non-natives to move in), but also toward the future. How might conditions change, and what plants are best suited to adapt to those changes – be it drought, flood or fire? 

Seeds should be selected based on your restoration goals. Are you creating a pollinator meadow or trying to stabilize a streambank? Hopefully, you’ve already laid out these goals in your Restoration Plan. Your seed mix, plus any remaining weed or native seeds that survived the site preparation process, will be what determines the type of plant community that comes up in the spring (or fall if your seeding happens in the spring – see our Site Prep article for a discussion on the best time to plant your seeds). 

Before you purchase seed, be sure to do some research on the plant and the conditions in which it likes to grow. This way, you can avoid planting seeds that will not be successful in your site.

Seeding Methods

Sean & Lilia hand seeding and raking a restoration site after thinning and controlled burning

There are two common ways of actually getting the seed on the ground: broadcasting by hand and drill seeding using a tractor.

  • Broadcasting. Best for smaller sites (half an acre or less). To broadcast seed, simply walk in a regular pattern across your site, throwing by hand and attempting to distribute it as evenly as possible. Or, use a “belly-crank” seeder. In either case, broadcasted seed should be distributed at a higher seeding rate than if using a drill seeder. Because broadcasting doesn’t actually bury the seed in the soil, these seeds have a slightly lower rate of success, and may be eaten by birds and field mice! On smaller scales, this effect can be mitigated by raking, or rolling over the seed to press it in. 
  • Drill seeding. A drill seeder pulled behind a tractor is a fantastic way to distribute seeds evenly and get them in the soil without turning it over (bringing buried weed seeds to the surface where they can germinate). A seed drill doesn’t do any actual drilling; it can be more accurately described as placing the seeds underground, at a rate and a depth specified by the user. 

Belly crank seeders and rollers can usually be rented out by the day from a local farm supply store, home improvement store or equipment rental business. Jackson Soil and Water Conservation District has a drill seeder for rent.

Seeding Rate Calculations

By choosing a specific seeding rate and sticking with it, we can introduce scientific accuracy to the art of restoration. We start with a target seeding rate and work from there. 

What is seeding rate? Simply put, it’s the number of seeds you need to apply to a given area to achieve the desired plant coverage. Most restoration projects use a seeding rate of between 30-60 seeds/square foot. Knowing your seeding rate will help you determine the number of pounds or ounces of seeds to purchase.

What’s the ideal seeding rate for your site? It depends on your goals, seeding method and site conditions:

  • At the lower end of the range (30 seeds/sq. ft.), you’ll be seeding a site that has been well prepared (no weed seeds; flat, smooth soil surface), and has excellent soil. You have a seed drill or some other way of accurately distributing the seed, and you want plant coverage to be somewhat sparse (perhaps for bee nesting habitat). 
  • At the higher end of the range (60 seeds/sq. ft.), you are trying to seed heavily to outcompete weeds that survived your site prep, there’s a slope or other factors that could cause seeds to wash or blow away, and your goal is to have dense plant coverage at the site.

Now let’s talk about your seed mix. You don’t want a monoculture of one seed in your restoration site, but a mix of different species — it goes back to that plant community idea we were discussing earlier. Before you can figure out how much of each seed to buy, you’ll need to decide on what percentage of the total mix that each type of seed will occupy. For example, if your goal is to restore a native grassland meadow, you might shoot for 50% Danthonia californica (California oatgrass). 

Finally, the seeding rate is dependent on the number of seeds per pound, which is different for each species. If you plan to purchase seeds from the RNPP Seed Sale, you can find the number of seeds per pound on the species description page or here in this handy table. 

How to Use the Calculator

We created this spreadsheet as a quick method of calculating the quantity of seed you need to buy. You’ll need to first input the following data:

  1. Your target seeding rate (# of seeds/square foot)
  2. The number of acres to be seeded
  3. The names and number of seeds per pound of each species you want to include in your seed mix (seeds/lb can be found HERE or on the species description page in the RNPP seed sale).
  4. The percentage of the seed mix that species will occupy 
  5. The cost per pound for each species

Here is what the calculator will give you after you enter the data above:

  1. How many pounds of seed you’ll need for each of the species in your mix
  2. The individual seeding rate for each species in your mix.
  3. The cost per species 
  4. The total cost of your seed mix

Restoration Best Practices: Developing an Ecological Restoration Plan

Posted on by Lilia Letsch

Are you planning on engaging in ecological restoration on your land? If so, an important first step is to develop a plan. It doesn’t have to be complex, but it is important to outline your plans, methods, and timeline so that you can keep on track and do the best you can for the area to be restored. Another reason to have an ecological restoration plan in place is to be able to share information with any agencies that you might be looking for support from. Additionally, the Rogue Native Plant Partnership’s annual native seed sale (next occurring in Fall 2020) requires seed buyers to have a basic restoration plan in place so that we know the hard-to-come-by seed is going to be used productively. 

Below we have laid out the information that is useful to have in your restoration plan. We encourage you to use this opportunity to learn as much about your land as you can – about the soil, plants, historical impacts, wildlife habitat potential, and anything else you can dive into – it’s a great way to get more connected to your land and be able to do your best in enhancing plant and wildlife biodiversity. You can also download an example restoration plan here (Word document).

Introduction to the land:

  • Location of land – the address, and the location on the landscape (hill slope, valley floor, wetland, etc)
  • Size of restoration site
  • Soil type (read our guide: How to Find Your Soil Type)
  • Ecoregion (find here: https://www.roguenativeplants.org/interactive-oregon-ecoregions-map/)
  • Habitats present (eg. riparian, woodlands, grasslands) and other main features (house site, road, pasture)
  • Map showing land (eg. screenshot from Google Maps, MyMaps, hand drawn map)
  • Relevant land use history
  • Brief description of specific area to be restored

Details of area/s of land to be restored (if more than one area, write up each set of details separately):

  • Location of area to be restored within land parcel (add a map if possible)
  • Current condition of area to be restored
  • List weed and native plant species – you can use apps like Google Lens and iNaturalist to help with identification.
  • List current and potential impacts on area to be restored (eg. weed drift from neighbors, too much sunlight on riparian zone) 
  • Describe restoration goals (eg. I want to remove the weeds from the creek banks and replant with natives to create shade for the water, or, I want to remove invasive grasses from my woodlands and increase the number of native grass and herb species that will benefit native pollinators)
  • Describe methods to be used in restoring area & timeline for each part of the process. Click on the links below for more information on each process. 
  • Timeline for every restoration phase

Any special considerations that need to be accounted for, eg.:

  • Oregon Dept. Fish & Wildlife plans required for certain riparian zones
  • Historical sites that may require protection

Additions:

  • Include list of observed native and weed plant species
  • Include list of observed wildlife on land
  • Include any relevant photos – eg. photos of area to be restored. Make sure to take after photos! 

Useful Documents: the Rogue Native Plant Partnership Resources Library is a fantastic place to learn more about a range of topics related to ecological restoration, from weed removal to harvesting native seed to growing native plants in containers, and much more. Here are a few documents we thought might be particularly useful for when you are writing an ecological restoration plan:

Native Plant Grower Profile: Holly Mills

Holly Mills is one of the local wholesale growers providing plants for RNPP’s native plant sale this spring. Her background is in organic vegetable gardening but she made the transition to native plant production for restoration projects a few years back under the guidance of James Kraemer of Silver Springs Nursery.

Below is a video interview we did with her about why she enjoys working with native plants and some of her tips on how to select the right species for your property.

Native Plant Grower Profile: Taylor Starr from White Oak Farm & Education Center

Posted on by Lilia Letsch

We recently caught up with Taylor Starr, co-founder and Executive Director of White Oak Farm & Education Center in Williams, OR. Taylor is one of the growers of the native plants we are currently selling through our RNPP Spring Plant Sale (ending April 16). Before moving to Oregon, Taylor worked as a farmer, landscaper, and teacher in Northern California and Washington State.  He has taught children organic gardening, natural history, and life sciences, and taught ecosystemology at UC Berkeley.  He graduated from UC Berkeley with a degree in Holistic Ecology in 2000.  Taylor grew up near the shores of Puget Sound, where he developed a love of the natural world through annual family backpacking trips in the Cascades and Olympics.  He currently directs things at White Oak, farms a wide range of fruits and veggies, teaches permaculture and sustainable living skills to kids and adults, and plays as much soccer as he can with his eight-year-old daughter.

Can you tell us a bit about your native plant growing business and how you started out in this line of work? 

Taylor: We run White Oak Farm & Education Center in Williams on 62 acres, where we have been for 18 years. We have been organic farming and running an environmental education center, mostly for kids but also for adults, focused on sustainable living skills, growing food and ecology. We’ve always had our own nursery for growing plants for our farm – for propagating fruit trees, berries, and hedgerow plants. But about six or seven years ago we started getting inquiries from people in the community about buying plants from us, so we started to ramp up production for local folks and that was pretty popular and successful, and got us excited about growing more plants. About two and a half years ago we started thinking about how we could make it a bigger part of the financial picture for supporting our organization and the farm, and what that might look like. I started researching around the valley and talking to different folks in the nursery trade, and especially focusing on small nurseries and what the niche was, what markets were underserved and what kind of opportunities existed. 

I met James Kramer from Silver Springs Nursery and he really got me excited about focusing on native plants, and specifically focusing on native plants for restoration, which fitted in really well with what we were doing on the land. We were growing native plants for our own restoration projects here on the property for erosion control. Mostly uplands plantings, but some riparian projects as well. So I had a little bit of experience with natives, and a lot of enthusiasm. I’m an avid outdoor person and backpacker, so I was really excited about partnering with James, and that’s what we’ve been doing for the last couple of years. We are mostly doing wholesale, but also growing for local nurseries and for the local community. We are really pretty new in the world of native plant commercial production, and it’s a really steep learning curve, we’re learning lots, and are excited to just dig in deeper. We’ve been expanding a good bit each year. This year I’ve got about 1600 sq feet of greenhouse space, and that much again of shaded growing space, and trying to grow a wide diversity of native plants and see what does best for us, and what the most demand is for, and go from there. 

Speaking of big learning curves, what are some of the biggest challenges you face with growing and selling native plants? 

Taylor: The biggest challenges we face in growing native plants is the transition from organic farming – where I have two decades of experience and everything is old hat and basic and simple – to the natives where every species has very specific requirements for germination, and very specific protocols as far as stratification and seed collecting protocols. You can’t just order locally adapted native plant seed from the catalog the way you can with vegetable seed. Every step of the process is much more complex and much more self-reliant. If I want seed for something I pretty much need to go out and find it myself in the wild, or partner with James or Holly Mills, another growing partner we have on these projects. 

Everything from seed collection all the way through to germination and growing the plants out is very specific for each species. I like that part of it because it’s a challenge, and it’s fun to have the challenge and feel like the success are bigger successes, but there’s definitely a lack of information about some of the protocols for these species, as well as the challenge of finding the seed and making sure the seed is viable and getting good germination.

On the selling side, I know the Rogue Native Plant Partnership is working on this issue, but being someone new in the world of commercial native plant marketing, it feels like there’s a little bit of a disconnect between the restoration project managers and the native plant growers. It’s going to be at least 12 months from seed collection to having the finished plant, so ideally 12 months ahead of time I would know, ok, there’s this much demand for this species, and this much demand for this other species, and I’m finding it’s a little hard to get that timing and demand information from the local players who implement the restoration projects. So that’s the biggest challenge, just knowing what the market is, and what plants are good to grow because there’s going to be a market for them down the road. There’s a little bit of security in knowing you can just keep watering them and hopefully there’s a demand for them the following year. It’s not like lettuce, where if you don’t sell it that week, it’s gone. 

On the flip side, what do you see as some of the biggest benefits to growing native plants as a commercial grower?

Taylor: The fact that within the restoration movement, and even the home gardeners and landscapers, it feels like there’s growing awareness and enthusiasm about the importance of planting drought-tolerant plants, planting to provide habitat for pollinators and other native species. It seems like there’s growing awareness about the importance of that, so it feels like a good time to be growing native plants. There’s only going to be more awareness and more enthusiasm for doing more restoration work. Obviously there’s plenty of landscapes that need restoration, so there’s no lack of demand from a purely restoration standpoint. From an economic standpoint there’s more awareness of how if we don’t take long term care of our riparian areas especially, the economic costs are going to be far greater than the cost of doing this work. I feel like it’s only going to grow over time as people become more educated.

For me – coming from a world of more annuals and food-based crops – I have more flexibility if things don’t sell at a certain time because native plants are still going to maintain their value as long as I can keep them watered and healthy in the pots. It feels like there’s a little more security as far as the value being maintained in the plants over time. 

Also I really like it because, labor-wise, there’s a lot of seeding work and seed collecting work in the fall, and through the winter there’s work with cuttings, and in the early spring there’s more seeding and greenhouse work. So it balances out really well with the annual vegetable and perennial fruit-producing season, which is busier in the spring and summer and the early fall. It works really well for me in terms of keeping folks on the farm employed throughout the season and having some income-producing projects happening on the farm during the winter months. It pairs really nicely for us with the farming. 

I know we’re not meant to have favorites, but do you have any native plants that you particularly love growing?

Taylor: I didn’t know we weren’t supposed to have favorites! It’s funny because I was thinking about that, and it really depends on the day, you know? I get a lot of satisfaction from growing big trees. We named our farm White Oak Farm because we have a couple of grandmother oaks on the property that are just super inspiring because I know they have been there for hundreds of years. The oak tree is such a keystone species in Southern Oregon, for food production for animals and habitat, and a food source for humans over the centuries. So I love planting oaks and acorns. Last year we did a big acorn collection project with some school kids who came out to the farm and collected thousands of acorns from two of our biggest acorn producing oaks. Unfortunately, we were going to plant them with the kids this spring during spring school visits, but of course like everyone else right now, our lives are a little bit topsy turvy so there’s no kids here to plant the acorns with us. So we’re planting them ourselves. 

I love to grow oaks and all the other big trees – our maple seedlings are two inches tall right now in their little pots and that’s super satisfying. I’ve also been really enjoying some of the shrubby species, the dogwoods and willows this winter have been great to work with. I love elderberry, so experimenting with seedlings and cuttings with elderberries is really satisfying. So a wide range are favorites depending on the day and what I’m working on.

Gardeners sometimes look to native plants as more likely to be deer-proof, but I’ve certainly discovered that’s not always the case. Have you discovered any native plants that you think are truly, really, actually, 100% deer-proof?

Taylor: One of my first jobs, when I was in high school in the summer time, was working for a local nursery and landscaper up in Washington, and one of the first things he said was, “Never tell a customer that something is 100% deer-proof because I can guarantee the deer will eat that plant the first week it goes in the ground.” I think deer have been eating native plants for as long as there’s been deer, so I don’t know that there’s anything specific to native plants that makes them less likely to be popular with the deer. I’ve seen deer eat almost anything, I think it just depends on the time of year. 

In the summer, when it’s so dry up in the hills and the deer come down to the irrigated yards and the edges of the irrigated zones, they are just so hungry for anything that’s got moisture in it. I would say that the less irrigated the area, I’ve noticed the deer are less likely to browse. They really smell the water, so the faster growing, the more well-watered and fertilized the plant, the more likely they are to eat it, as far as I’ve been able to notice. 

When talking to gardeners and land stewards, what do you most often find yourself saying to encourage them to purchase and grow native plants?

Taylor: I’m a terrible marketer so I don’t know if I necessarily say anything to anybody to try and encourage them to do anything! People are just going to do what they are going to do. I take the approach that, hey, I’m here growing these things, if you want them that’s great. I’d love to sell them to you. There’s so many benefits that are so obvious, from drought-tolerant to habitat creation. I feel like the pollinator angle has gained a lot more awareness over the last few years, and it’s been cool to see customers ask about that and think about that more. But I’m a big fan of hedgerows in general, and trying to encourage people to plant hedgerows for privacy, for shade, for habitat, for the pollinators, for hopefully some products that people can harvest as well. Maybe berries for medicine, maybe basketry materials, or browse for animals. There’s just so many benefits to planting natives, and I feel like the people I usually find myself talking to about this stuff already know it’s a good idea, and it’s more about helping them to get what’s the right thing for their site. I think that there’s definitely growing enthusiasm for planting natives and I think that’s really exciting. 

Do you have any tips for people that want to propagate native plants for their own use? Or as a business?

Taylor: I would probably say the same advice for both situations, which is just to start experimenting. That’s how we started doing the nursery on a commercial basis. It was just years of experimenting and growing plants for ourselves to plant out on the farm and seeing what we enjoyed growing without having to invest a lot of money or a lot of time into infrastructure. Playing around with different species and experimenting, and then seeing if it’s something you like to do and something you can see having economic potential. I think just starting out by diving in and doing things on a small scale, and not being afraid to fail. 

Going out and seeing what kind of seeds you can collect in your neighborhood or on your own land, and playing around with it, seems like the best way to approach it from the small scale home nursery perspective. But even if you’re thinking about doing something commercial, I think messing around with it on a small scale makes a lot of sense before diving in and spending a bunch of money on infrastructure. Because it does take having the greenhouse space and having the controlled environment to work with, and having the irrigation, and having the pots or the soil. For us, because we were coming from farming, we already had a lot of those things in place and we were able to repurpose this corner of the greenhouse or repurpose pots, and slowly build up the infrastructure to run the nursery as its own little business. At least for me, that was a good way to do it because it lessened the risk of tackling something that could prove to not be successful, and made it easier to slowly get going. I would just experiment, I think that’s the best way to get into nearly any new activity.

Leaves removed to expose bare earth before seeding

Seed broadcast and raked into earth. Hay applied to cover seeded bare earth.

Plot development and monitoring

A 50 x 100 foot plot was established on 11-9-2018. Leaves were removed to expose the bare soil and the seeds were raked into the ground. The plot was treated with 6 lbs per acre (.70 lbs) of Elymus glaucus. On 1/3 of the short side of each plot (16.5 x 100 feet), an additional 6 lbs per acre (.23 lbs) was applied. On ½ of the long side of the plot (50 x 50 feet), hay was applied to cover the bare ground. Didn’t get final pictures but it sounds like the seed didn’t take very well. A 10 ft x 10 ft test plot of Pseudoroegneria spicata was created nearby on 11-9-2018. Leaves were raked to remove the bare soil, seeds applied, raked in, and the soil was left bare. No luck here either.

February Native Plant of the Month: Snow Queen

Posted on by Lilia Letsch

RNPP has a Native Plant of the Month column in the Rogue Basin Partnership newsletter! You can find the full RBP February newsletter here, and our Native Plant of the Month Column copied below.

Snow Queen (Synthyris reniformis) can be seen blossoming close to the ground in coniferous forests and woodlands from early February, making it one of the earliest native blooms to be seen each year in southern Oregon. But it can be very easily overlooked at only 2-6 inches tall, with flowers varying from white to blue to purple, so keep your eyes on the ground if you want to spot them. I noticed this lovely specimen (pictured) on the Sterling Mine Ditch trail near the Little Applegate recently, and once I noticed this plant, I suddenly realized they were everywhere!

There are six varieties of Synthyris (in the Figwort family) in Oregon, but the Snow queen is the species most commonly found at low to mid elevations. It is native to the Pacific NW, from the Puget Sound in Washington, to Northern California. With its flowers arriving so early, the Snow queen is an important source of food for pollinators and nectar eaters. This adds to the many reasons why the perennial Snow queen can be a great choice for planting in your garden.

Restoration Best Practices: Site Preparation Methods

Posted on by Lilia Letsch

Welcome to the first post in our new series about best practices in ecological restoration. Through this series we hope to provide an accessible but thorough outline of the most important elements of implementing ecological restoration projects. Nearly everything to do with ecological restoration is complex, and there is still a lot of research being done into best practices, so it is important to keep an eye open for new information. Our goal is to outline the basics, and point you in the direction of more detailed information if you choose to go in depth on any topics.

We are starting our ecological restoration best practices series with a focus on site preparation. The importance of site preparation is often underestimated but can have a huge impact on the success of your restoration project. If you would like to go more in depth into a range of site preparation issues, we highly recommend the Xerces Society “Organic Site Preparation for Wildflower Establishment” document.

Timing

Seeds:

The time of year that you choose to disperse native plant seeds at your restoration site is extremely important. Native plant seeding usually happens either in the fall or spring in the Pacific Northwest. In Southern Oregon, fall is generally the best time to get seeds in the ground, as it gives time for in-ground stratification (cold treatment) and mimics the seeding cycles of most native plants. Early spring can also be a hard time to do site preparation if the ground is too wet, or covered in snow! But spring seeding is still a good option if site preparation is possible and the seeds you are using don’t require a deep winter stratification.

Containerized Plants:

Planting potted native plants is generally best done in the fall to provide time for settling and root growth, but early spring is an option if the ground is not too frozen and supplemental water can be provided if spring rains are not sufficient.

Surveying Your Site

Recording the plants that already exist on your site is a great opportunity to better know the plants, their needs, and ways the native plants can be protected during the site preparation phase of your project. You can just write down a list in a notebook, or keep a spreadsheet where you can update information about shifts in flowering, seeding and other interesting observations you make. It’s also a really good idea to keep a record of any weeds you can identify and get to know their lifecycles, best times of year to work on removing them, and the best practices for how to reduce their impact on your restoration site.

Weed Removal

Inadequate weed suppression can have massive impacts on the success of your ecological restoration project. For most weeds, an important control method is removing or cutting back the plant before it goes to seed. Different weed plants tend to require a variety of removal methods, used in progression. Some of these methods include solarization and sheet mulching, mowing, flame weeding or burning, and selective and careful herbicide (incl. organic) use. To dive further into best practices for removing some of our most detrimental weeds in Southern Oregon, check out these documents:

Solarization and sheet mulching: these methods are best used for smaller sites without steep slopes. Solarization utilizes large sheets of clear UV-stable plastic to cover an area containing weeds for 2-6 months in warmer climates, and up to 6 months in colder climates. Many trials have shown solarization to be an extremely successful method of weed removal, as the heat that builds up under the plastic not only kills plants, but also any weed seed bank that has built up in the soil. Occultation is a variation on solarization, where thick black plastic tarps are used to cut of access to sunlight, and produce large amounts of heat. Sheet mulching is useful in areas that are too shady for solarization to be effective, or in areas where laying out a large piece of plastic is impractical due to landscape features. Sheet mulching involves layering nitrogen and carbon based materials to smother weeds and stop the seed bank from being able to germinate. For example, a layer of nitrogen-based material (eg. animal or plant composted materials, pellets, meals, grass clippings) is then topped with a layer of carbon-based material (eg. cardboard, paper, sawdust, woodbark), and then these layers are repeated 1-2 more times, making sure that a heavier carbon-based material is on top to hold everything down.

Mowing: this can be a very useful tool in ensuring a weed population doesn’t get to produce seed. For most weeds, using a mower or weed wacker to remove any seed heads before they -are pollinated is a fast and efficient way to deplete the plant’s ability to reproduce. That said, it can be hard to time mowing so that the plant doesn’t have the time and energy to enter into the flowering stage again, while also navigating any fire season restrictions on cutting dry grass. This method involves getting to know your weeds and their reproductive cycle well, and should be used in tandem with other weed control methods.

Hand-held flame weeder

Fire: flame weeders are an excellent resource for spring-time weed control. They must be used with great caution and attendance to fire restrictions, but they are an efficient and targeted method for removing weeds without impacting surrounding native plants. If you have a large area that would benefit from prescribed fire, get in touch with your local prescribed fire practitioners to see if there are any opportunities available for this work to be done on your land by trained professionals. In Southern Oregon, The Klamath Siskiyou Oak Network may be able to point you toward prescribed fire resources.

Smother cover crops: in areas where weed pressure is low to moderate, cover crops can be used to smother weed plants. Smother cover crops can also improve soil health and provide temporary forage for wildlife, including pollinators. This technique is best used on farmland or pasture that has access to irrigation and farming equipment. Certain varieties of buckwheat, sorghum, millet, oats, rye and vetch can be planted. Depending on the cover crop planted, they can not only compete aggressively with weeds for space, but also alter the nutrients in the soil and release allelopathic substances into the soil to make it undesirable for weed germination and growth. Timing and duration of the cover crop also varies depending upon species, but is very important to ensure that weed suppression is maximized.  

Herbicides: using synthetic herbicides to control weeds is a very contentious issue, but best practices generally determine that they should be used as a last resort, and in a very targeted and well-planned manner. This is particularly important in riparian zones where herbicides can make their way into the aquatic ecosystem. Herbicides alone are rarely able to control the most problematic weeds, and should be considered part of a regime that involves other weed control methods. There are some organic herbicides available to use, and successful use depends on targeted plant species. For more information it is worth checking out the “Roadside Habitat for Monarchs: Monarch Butterflies, Weeds and Herbicides” and “Organic Pesticides: Minimizing Risks to Pollinators and Beneficial Insects” documents produced by the Xerces Society.

Ground Disturbance

If you are utilizing native seeds in your restoration project, gentle ground disturbance is a useful step to take just before you are set to distribute the seed. It helps the seed penetrate the soil more rapidly and protect it from being washed elsewhere by rain, and from browsing wildlife (birds love seed!).

Site preparation: raking in the Ashland watershed

Raking: this is a great method for restoration projects in woodlands, forest floors, sloped locations and small areas being seeded. Hand raking disturbs the ground enough to allow seed to get into the soil, but doesn’t disturb soil structure or existing native plants as much as more intensive ground disturbance. It also allows you to easily avoid any preexisting native plants that you are trying to protect.

Light tillage: you can also use a small tiller / cultivator to prepare an area for seeding. This is particularly useful in pasture and farmland. If you have a weed issues, this is a method that should be considered carefully, as ground disturbance can expose weed seed banks in the soil to the ideal conditions for growth.

January Native Plant of the Month: Snowberry

Posted on by Lilia Letsch

RNPP has started writing a new Native Plant of the Month column for the Rogue Basin Partnership newsletter! You can find the full RBP January newsletter here, and our Native Plant of the Month Column copied below.

Snowberry (Symphoricarpos albus) is a common deciduous shrub, growing 3-6’ in riparian, swamp, moist meadow and open forest habitats, from sea to middle elevations. What makes it so lovely at this time of year is that its leafless stems are graced with clusters of bright white berries that sharply stand out against the winter landscape.

Snowberry is in the Honeysuckle family, and just like Honeysuckle berries, they are not edible to humans. The whole plant is toxic to humans, although records show that Native Americans have used the berries medicinally for a variety of purposes, and the stems for arrow shafts.

The berries have a mild saponin content, which produces foam when mixed with water. The whole plant is excellent grazing for wild and domestic animals, and birds enjoy the berries and cover that the shrubs provide. Birds also disperse the seeds widely, although the plant’s main reproductive method is to sprout new shoots from its spreading rhizome. As a result, you can often see it growing in quite substantial thickets, which provide great cover for small mammals.

If you are looking to replant a disturbed or eroded site, Snowberry is a great choice due its relatively fast growth and rhizomatous spreading. It grows in full sun, but tends to prefer some shade, and well-drained soil.

November Native Plant of the Month: Rubber Rabbitbrush

Posted on by Lilia Letsch

RNPP has started writing a new Native Plant of the Month column for the Rogue Basin Partnership newsletter! You can find the full RBP November newsletter here, and our Native Plant of the Month Column copied below.

Native Plant of the Month: Rubber Rabbitbrush

Rubber Rabbitbrush (Ericameria nauseosa) is a small perennial shrub that grows in a wide variety of harsh habitats from the west coast all the way to Texas and North Dakota. In the Southern Cascades you can still see the last of its flowers in November, but its prime flowering season is August-October. It’s bright and prolific yellow flowers are a very abundant source of food for pollinating insects and birds, and the leaves are an important winter food for browsing mammals.

Rubber Rabbitbrush is an excellent revegetation plant in disturbed areas, as it propagates easily and grows fast in a range of poor soil conditions. It also thrives in dry environments, making it a great choice for xeriscaping (landscapes designed to reduce or eliminate the need for irrigation). It is often found growing in desert-like habitats alongside sagebrush – both of which are in the Asteraceae (sunflower) family. Its deep growing roots also make it very useful for stabilizing ground prone to erosion or damaged by mining.

Ethnobotanical uses of the plant include making a yellow dye from the flowers, using the rubbery stems in basket making, and making tea and chewing gum. As its name suggests, it can actually be used to make rubber from the plant’s sap. Rubber production potential varies depending on the growing conditions, but it is known to produce more rubbery sap in dryer, hotter conditions.

Taxonomy fact: the “nauseosa” species name relates to the pungent smell the plant gives off when the leaves are rubbed. Some say it’s a pineapple-like aroma, while it’s more foul and rubbery to others.

 

October Native Plant of the Month: Vinegarweed

Posted on by Lilia Letsch

RNPP has started writing a new Native Plant of the Month column for the Rogue Basin Partnership newsletter! You can find the full RBP October newsletter here, and our Native Plant of the Month Column copied below.

Native Plant of the Month: Vinegarweed

While walking through open grassy woodlands and prairies during late summer, you may have encountered a strong smell of minty vinegar on the breeze, and maybe even heard the hum of insects that eagerly congregate on the annual herb commonly known as Vinegarweed. The attractive purple flowers are an important late summer pollen source for many insects, with flowers known to bloom into October.

This sun-loving herb is quite shade intolerant, and prefers dry soils below 2,200 ft between Washington and Baja California. It is known to have phytotoxic properties that prevent other plants from growing happily around it. This could make it an excellent plant for competing with invasive herbs. It is also unlikely to be palatable to browsing animals due to its highly fragrant oils. Seeds mature and can be collected in late fall, and sown directly (raked into soil) in fall or early spring.

Vinegarweed is known to be highly medicinal, and has been used by west coast tribes for many healing purposes, including for treatment of colds, throat inflammation, headaches, infected sores and aching teeth.

The species name Lanceolatum means “lance-shaped”, which relates to the shape of Vinegarweed’s leaves. It’s always nice when the scientific name relates to the plant’s appearance! Its lovely little purple flowers are also a great way to identify the plant, but the easiest way to identify Vinegarweed by far is its powerful fragrance – you can’t miss it!

Upper Table Rock Seed Blitz and Yellow Starthistle Pulls

Posted on by admin

June 2017 – June 2019

For the third year in a row, volunteers with The Nature Conservancy and the Rogue Native Plant Partnership gathered on the slopes of Upper Table Rock to collect wildflower seed for future restoration projects and hand pull the highly invasive yellow starthistle.

Yellow starthistle (Centaurea solstitialis) is an exotic annual herbaceous plant in the knapweed genus. The seeds from this plant can germinate whenever there is enough moisture in the soil. It starts as a small bluish green rosette and grows slowly through the winter months. Once the heat of the summer comes this plant bolts to produce yellow flowers subtended by thorny spikes.

Although yellow starthistle is an annual species that dies every year, it is able to produce a long taproot that depletes the soil of moisture making it nearly impossible for native species to grow nearby. This species is particularly difficult to manage because it can continue to produce flowers and seeds even after continual mowing or grazing by producing flowers very low to the ground. At Upper Table Rocks, years of volunteer-based hand-pulling has resulted in the almost complete eradication of this plant from the wildflower meadows at the site!

Ecological restoration involves many steps. The first step is often to change the disturbance patterns at the site (in this case stop the yellow starthistle invasion) followed by seeding the site with native wildflower and grass seeds. These precious seeds are hard to come by and expensive in Southern Oregon. To help tackle these challenges, volunteers with The Rogue Native Plant Partnership help to collect wildflower and grass seeds from native plants nearby. Once enough seed has been collected, it will either be used directly on the site or grown out at a nearby farm (increased) if more seed is needed than can reasonably be collected from wild plants.

Restoring huckleberry habitat as a cultural resource

Posted on by Lilia Letsch

On September 26th a large group of volunteers including Cow Creek Band of Umpqua Tribe of Indians members, Forest Service and BLM employees and Rogue Native Plant Partnership volunteers converged on a recently burnt area just outside the town of Prospect in the High Cascades to help replant 1500 mountain huckleberry (Vaccinium membranaceum) plants.

The area was burned during the 2017 Broken Lookout fire. The well-established plants were grown by the Forest Service’s nursery in Dorena from seed fortuitously collected onsite only two weeks before the Broken Lookout Fire started. This project is a collaboration between the Forest Service, the Cow Creek Band of Umpqua Tribe of Indians and the Rogue Native Plant Partnership to restore an important cultural food resource.

It was a brisk but beautiful day up in the mountains, and after a smudging ceremony led by members of the Cow Creek Tribe, everyone got their planting equipment ready and hiked into the burn area to get huckleberries into the ground. In addition, monitoring plots were surveyed as part of a multi-year effort to obtain data that will help develop an understanding of the success of the replanting efforts.  There are still 8000 more plants to go in the ground, with that work being completed by contractors at the time of writing.

Huckleberries continue to be an incredibly important cultural food resource for Native Americans, and so many community members and government agencies coming together to support the replanting efforts is a powerful acknowledgement of understanding the huckleberry’s cultural significance. Thank you to everyone who came out for this great replanting effort!

Collecting milkweed seedpods for local pollinators and landowners

Posted on by Lilia Letsch

Ten Rogue Valley community members come together at the Forest Service’s J. Herbert Stone Nursery in Central Point to volunteer for a milkweed seedpod collecting event on September 9th. Even with a decent breeze sending the seed fluff (known more officially as “coma”) flying everywhere, we still managed to collect large amounts of both narrowleaf milkweed (Asclepias fascicularis) and showy milkweed (Asclepias speciosa) seed pods. The beds of narrowleaf and showy milkweed have been funded by the US Fish & Wildlife Service (USFWS), and the seeds will be used in special seed mixes being prepared for landowners to enhance pollinator habitat on private lands in the region.

Milkweed is a fantastic perennial flowering herb that is much loved by many pollinators, including the at-risk Monarch butterfly. Not too long-ago milkweed was an incredibly widespread plant, but has been eradicated in many areas in favor of agricultural crops, and now faces a lot of competition from introduced invasive plants. Luckily it is an easy plant to grow, and efforts are being put into introducing it back into the landscape on a broader scale. It couldn’t happen soon enough for the Monarch!

Many thanks to all of the volunteers who came out to help collect milkweed seeds and contribute to important pollinator habitat restoration!

Interesting taxonomy fact: In 1753, Swedish Botanist Carl Linnaeus named the genus Asclepias after Asclepius, the Greek god of healing.

Restoring disturbed ground on Mt Ashland with native forbs

Posted on by Lilia Letsch

June 2nd, 2019

We had a fantastic day on Mt Ashland on June 1st, working with a group of volunteers to plant out 4,500 native plant plugs in an area next to the Mt Ashland lodge that was recently disturbed by heavy machinery. Thanks to the folks at the Mt Ashland Ski Lodge for helping organize volunteers and providing snacks and drinks for everyone!

The plants were grown by Silver Springs Nursery in the Applegate, from seed that we collected in 2018 on Mt Ashland. The species that were planted out included Oregon Sunshine (Eriophyllum lanatum), Coyote Mint (Monardella sheltonii), Yarrow (Achillea millefolium), Roemer’s Fescue (Festuca roemeri), Squirretail grass (Elymus elymoides) and Sulphur Buckwheat (Eriogonum umbellatum). Once grown in, these plants will create a beautiful meadow of wildflowers and native bunch grasses, and great habitat for pollinators and birds!

Post-planting care will involve regular watering for the first year, and ensuring that the area is cordoned off from the public so that the small plants won’t be damaged under foot. We look forward to monitoring the survival rate and growth of these plants, and enjoying the first flush of wildflowers next spring.

Thanks to the amazing volunteers!

Growing plants for seed production at Long Shadow Fields

Posted on by Lilia Letsch

April 25, 2019

Long Shadow Fields in Talent is one of a handful of local farms working with the Rogue Native Plant Partnership to develop a new model of native forb seed production. Seed for native forbs – herbs, and grasses – can often be hard to come by in the amounts required for local ecological restoration projects. Growing such plants out for seeds is often cost prohibitive due to the amount of time it can take for plants to develop to the flowering stage, and the amount of labor required to harvest the seed. But through a non-profit / small farm partnership, we are hoping to alleviate the risks and pressures of growing native seed for restoration projects in the Rogue Basin.

Gary Kliewer at Long Shadow Fields grew a selection of native herbs and forbs from seeds that RNPP supplied from our wild seed harvesting events. A volunteer planting event was organized to help get a lot of the small native herbs in the ground. RNPP will continue to support Gary’s native seed production through volunteer labor, funding through grants, and technical support from a network of other experts in the Pacific Northwest.

The volunteer planting event on April 24th was a great success, we planted hundreds of native plugs and did some great networking and knowledge sharing. Thank you so much to everyone that came and helped! Keep an eye open for future events at Long Shadow Fields and other local farmers we are working with to grow regionally adapted native herbs and grasses for ecological restoration projects happening in our community.
