Seeding Your Site: Methods, Rates and More!

Posted on by

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

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:

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

Posted on by

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

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.

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

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

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. 

Occultation with silage tarps at Jackson County OSU Extension

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.

Keep an eye out for our next blog post about best practices in native plant seeding for your ecological restoration project! Don’t forget that we are always updating the Rogue Native Plant Partnership Resources Library with new useful resources for ecological restoration projects – from backyards to woodlands and everything in between!

January Native Plant of the Month: Snowberry

Posted on by

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 it’s 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 it’s 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

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

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

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.

This slideshow requires JavaScript.

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

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.

This slideshow requires JavaScript.

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

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.

This slideshow requires JavaScript.

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

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!

This slideshow requires JavaScript.

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

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.

This slideshow requires JavaScript.

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.
