The Corvallis Plant Materials Center (ORPMC) provides plant solutions for western Oregon, western Washington, and northwestern California. The Center’s service area includes the northern Pacific Coast Range, Willamette Valley and Puget Sound, as well as Olympic, Cascade, and Siskiyou Mountains of western Washington and Oregon.

Degraded soil health due to compaction, loss of soil organic matter, poor soil structure, and low microbial activity is a primary resource concern on cropland, pastureland, and forestland. Erosion from heavy rainfall during the winter is a critical problem on cultivated cropland, heavy use areas of pastures, logging areas, and roadsides. Water quality is a main concern in areas of concentrated livestock, farming, and urban activities. Degraded streambanks, wetlands, and upland prairies need enhancement and restoration for fish and wildlife habitat. Native pollinators and beneficial insects need habitat enhancement to maintain their populations and provide important crop pollination and pest control services.

The Corvallis Plant Materials Center’s primary mission is to develop new technology in plant propagation and establishment, seed production, revegetation, and restoration, and to develop new native plant sources for use in wetlands, uplands, and riparian areas.
