Description of the Corvallis Plant Materials Center Service Area

The Corvallis PMC 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.

The rainfall of the area ranges from 200 inches near the coast to 20 inches in some valleys. Abundant rainfall contributes to excessive erosion in winter and spring. The topography and natural vegetation is typified by heavily forested coastal terraces, steep mountains, grass balds, foothills and valleys, nearly level to gently sloping flood plains with woodland prairies, and Savanna vegetation in the Willamette valley and Puget lowlands. Agriculture and timber production are important to the region. Products include lumber, grass and legume seed, grain crops, nursery stock, dairy, Christmas trees, nuts, fruits, and vegetables.

Wind and water erosion are critical problems on coastal dunes, roadsides, construction sites, dredge spoils, cultivated horticultural cropland, and logging areas. Water quality is a main concern in areas of concentrated livestock, farming, and urban activities. Degraded fish habitat, streambanks and wetlands are in need of enhancement and restoration.
