"Plant Solutions for Conservation Needs"

Developing plant species and plant technology to improve plant production and health, and help solve natural resource concerns is one of the main objectives of the plant materials program. Finding the right plant or plants for the job is important when dealing with forage production, erosion control, habitat restoration, and filtration of excess nutrients or sediment.

The NRCS Plant Materials Program has developed many native and introduced cultivars that have proven successful for forage/range production, revegetation, and erosion control. Proper seeding and planting procedures are essential to assure plant species establishment. The following plant material information will assist agency personnel and landowners with proper species selection and establishment to serve their conservation needs.

The Washington State Plant Materials Center website provides additional regional conservation planting information.

The three state area served by the Pullman PMC includes eastern Washington, eastern Oregon (east of the Cascade Mountain range), and northern Idaho. Testing has been performed at a number of locations but currently is concentrated at Pullman and the WSU Dryland Research Unit, Lind, WA.

Additional regional technical references, plant fact sheets, plant guides and technical notes can be found on the Idaho Plant Materials site.
