Environmental Protection Agency

The ecoregion maps provided on the NSN website have been derived from the Environmental Protection Agency's Level III Ecoregions of the Continental United States (USEPA, 2000 revison of Omernik, 1987). NSN utilizes the EPA maps because they incorporate spatial variation in climate, mineral availability (soil and geology), vegetation and physiography and relate well to what is encountered "on the ground." Omernik and other EPA staff at the Corvallis office have generously provided the Native Seed Network with ecoregion maps, ecoregion descriptions, and guidance in understanding how these maps were developed.

The Nature Conservancy

As the premier land conservancy organization in the world, The Nature Conservancy’s mission is to preserve the plants, animals and natural communities that represent the diversity of life on Earth by protecting the lands and waters they need to survive. 


NatureServe's mission is to develop, manage, and distribute authoritative information critical to the conservation of the world's biological diversity. NatureServe provides the context, analysis, and interpretation that transforms biological data into conservation knowledge. The Ecological Systems being developed by NatureServe have assisted NSN in developing plant communities and species recommendations.

North American Grouse Partnership

The North American Grouse Partnership (NAGP) is a coalition working to promote the conservation of Grouse and the habitats necessary for their survival and reproduction. The Native Seed Network is working with NAGP to be an additional conduit for the information they discover and to facilitate the education and public relations mandate of both organizations.

Institute for Applied Ecology

The Native Seed Network is a program of the Institute for Applied Ecology, Inc., a 501(c)(3) non-profit organization established to conserve our natural environment and educate the public about issues of conservation concern.

Oregon State University Seed Laboratory

The Oregon State University Seed Laboratory is the official laboratory in Oregon State.  The laboratory, along with the OSU Seed Certification Program, forms part of the larger Seed Services Program of Oregon State University.  The lab provides valuable seed testing services to organizations and individuals that produce, clean, preserve, market or use seeds in commercial production and reclamation activities. Testing services are for a broad range of species including grasses, cereals, legumes, vegetables, flowers, trees, shrubs, and native species. Tests available are purity test that indicates the level of pure seeds, inert material and crop or weed contaminants; viability by TZ that indicates the number of seeds that are alive; germination test, X-ray test to examine the internal tissues of seed; seed count to determine the number of seeds per pound; seed moisture content test to determine it needs further drying etc. E-mail, Phone 541-737-4464 and Fax 541-737-2126.

The Germplasm Resources Information Network (GRIN)

The Germplasm Resources Information Network (GRIN) taxonomic data provide the structure and nomenclature for the accessions of the National Plant Germplasm System. GRIN is managed by the Database Management Unit of the National Germplasm Resources Laboratory, Agricultural Research Service, USDA. The Native Seed Network plant database was designed to be able to cross-reference with GRIN.

Native Plant Network - Propagation Protocols

The Native Plant Network is a tremendous resource for information on how to propagate native plants of North America (Canada, Mexico, and US).   The database also enables users to upload protocols of species that they have grown successfully.  Many recommendations are from the USDA NRCS Plant Materials Centers.

Natural Resources Conservation Service (NRCS) Plant Materials Program

Plant Materials Centers have been developing native plant materials and technology for many years. See the NRCS Plants Database Fact Sheets for restoration use, cultivation, and descriptions for a number of native species. The NRCS Plant Materials Center in Corvallis has partnered with the Native Seed Network in performing a common garden study for the native grass Festuca roemeri, an important, vastly diminished component of upland prairie systems in the Willamette Valley of Oregon.

Oregon Flora Project

The Oregon Flora Project is developing an extensive database of plant occurrences based of Herbarium voucher specimens. Currently, there is no modern flora of Oregon. Nearly four decades of biosystematic research and plant exploration have rendered the most recent flora (Peck 1961) out of date.  In addition to a Flora of Oregon (with keys, descriptions, and illustrations), the OFP will produce a checklist of Oregon’s native and naturalized vascular plants and an Oregon Plant Atlas.

Oregon Natural Heritage Information Center

Natural Heritage Programs gather, manage and distribute detailed information about the biological diversity found within their jurisdictions.  Detailed, credible science combined with standardized data collection and management allows information to be shared. Currently, the Oregon Natural Heritage Information Center is assembling species lists from plot data in Southeast Oregon for NSN.  These species lists will be integrated into the National Vegetation Classification System’s plant associations and ecological systems, forming the basis for Community Classifications and Focus Lists in the NSN website.

Native Plant Policies

 1995 Executive Memorandum on Landscaping Guidance

"Federal agencies, Federal projects or federally-funded projects shall incorporate regionally native plants in site design and implementation where cost-effective and to the maximum extent practicable. Federal agencies shall strive to avoid or minimize adverse impacts of proposed actions or projects on existing communities of native plants."

Seed Certification

Seed certifying agencies provide an independent third-party oversight of seed production through a process of documentation, inspection, sampling, testing, application of standards, and final tagging of seed lots.  Each state assigns responsibility for seed certification to a member organization.  The programs below have active native plant programs.
