Regional Native Seed Cooperatives: working toward available, affordable, and appropriate native seed

Author: Smith, S. Date: 2017

Abstract: Regional native seed cooperatives are emerging as a tool to vastly improve the availability of genetically appropriate native seed. Within a cooperative, practical and ecological requirements for native seed are balanced by bringing users and producers together to jointly develop genetic protocols. Regional native seed cooperatives promote a novel agricultural niche that requires the development of new farms, infrastructure, and techniques. The South Sound Prairies partnership has a successful cooperative that is used here as a case study to explore this model of seed production.

Propagation of Interior British Columbia Native Plants from Seed

Authors: Hudson, S. & Carlson, M. Date: 1998

Abstract: British Columbia’s considerable diversity of soils, topographies and climates have given rise to a rich variety of native plant species. Many commercially valuable tree species have well established protocols for seed collection, planting stock production, seedling handling and planting. Comparatively little is known about these activities for non-commercial shrub and tree species. Many of these deciduous shrub and tree species are being used for watershed restoration and rehabilitation of eroded slopes, road edges and landings. Demands for planting stock are increasing each year.

Native Plant Propagation and Restoration Strategies

Author: Haase, D. and Rose, R. (OSU) Date: 2001

Abstract: Propagation and planting of native plants for habitat restoration is a multi-faceted process. There are many issues over which there is general agreement among restorationists, but there are a number of subjects that cause disagreement. For example, restorationists often agree that native plants should be emphasized, but disagree over where seeds or transplants should come from. In this paper, I examine four areas of controversy: the use single or multiple sources of a species at a given restoration site (the SOMS debate), source distance of plant materials, the use of native plant selections, and the importance of one’s definition of “native plant.” I conclude that some of these issues may be resolved through careful research, while others will remain a matter of personal opinion, and can only be resolved through a clear statement and scope of objectives of each restoration project.

Manual and Land Cover Type Descriptions: Oregon Gap Analysis, 1998 Land Cover for Oregon

Author: Killsgaard, C. Date: 1999

In its Acoarse filter@ approach to conservation biology, gap analysis relies on maps of dominant natural land cover types as the most fundamental spatial component of the analysis for terrestrial environments. For the purposes of GAP, most of the land surface of interest (natural) can be characterized by its dominant vegetation. Vegetation patterns are an integrated reflection of the physical and chemical factors that shape the environment of a given land area. They also are determinants for overall biological diversity patterns, and they can be used as a currency for habitat types in conservation evaluations

Maximizing Seed Resources for Restoration in an Uncertain Future

Authors: Broadhurst, L., Jones, T., Smith, F., North, T. and Guja, L. Date: 2015

Abstract: Seed is fundamental to broadscale plant restoration when the goal is to re-establish species and ecosystems. But climate change is expected to significantly influence plant reproduction, affecting seed availability and viability as well as planting opportunities. Meeting growing restoration targets within these constraints in new and unfamiliar climates will be challenging. Consequently, we need to develop a range of flexible strategies to ensure that sufficient volumes of viable seed are available to take advantage of planting opportunities under novel environmental scenarios. This requires coordinated leadership to align funding and planting timelines, using seed production areas to improve seed supply, building and maintaining infrastructure to stockpile seed, encouraging research to overcome storage and germination constraints, and developing and implementing new technologies in all of these areas. Increased tolerance to risk and failure will also be required as the application of current restoration practices may not be appropriate as the climate changes.

Milkweeds: a Conservation Practitioner’s Guide

Author: The Xerces Society Date: 2014

The information in Milkweeds: A Conservation Practitioner’s Guide is gathered from interviews with native plant nurseries and seed producers, gained firsthand through Project Milkweed, and synthesized from scientific literature. It provides conservation professionals with information about optimizing milkweed seed production methods, offers guidance on incorporating milkweeds into restoration and revegetation efforts, and highlights milkweeds’ unique characteristics and value to wildlife. Native seed producers, restoration practitioners, land managers, monarch conservationists, gardeners, and landowners will all find this guide valuable.

Raising Native Plants in Nurseries: Basic Concepts

Authors: Dumeroese, Luna & Landis (eds.) Date: 2012

Growing native plants can be fun, challenging, and rewarding. This booklet, particularly the first chapter that introduces important concepts, is for the novice who wants to start growing native plants as a hobby; however, it can also be helpful to someone with a bit more experience who is wondering about starting a nursery. The second chapter provides basic information about collecting, processing, storing, and treating seeds. Chapter three focuses on using seeds to grow plants in the field or in containers using simple but effective techniques. For those native plants that reproduce poorly from seeds, the fourth chapter describes how to start native plants from cuttings. The final chapter provides valuable information on how to successfully move native plants from the nursery and establish them in their final planting location.
