Middle Fork Willamette River – State Wildlife Action Plan

Geographic boundaries of the COAs were updated for the 2026 State Wildlife Action Plan and the associated COA profiles are intended to provide additional information. Content of each COA profile is being refined and will be updated to reflect current conditions when feasible. Please help us by submitting information on Local Conservation Actions, Plans, or Potential Partners to: OCS.revision@odfw.oregon.gov.

The Middle Fork Willamette River COA (167 mi²) extends from Lookout Point Lake upstream along the Middle Fork Willamette River and into the surrounding forestlands as far east as Huckleberry Mountain. The area skirts along the northern edge of Oakridge, and goes north to Alpine Ridge. This COA is adjacent to the Upper Willamette River Floodplain COA.

Recommended Conservation Actions

Maintain or enhance in-channel watershed function, connection to riparian habitat, flow and hydrology
Maintain and enhance wetland and wet meadow habitat.

Maintain and restore existing habitat and ecological function, ensuring sufficient habitat complexity for wildlife.
Maintain and restore existing rocky bluff and shallow soil habitats.

Special Features

General

This COA contains many areas with shallow soil and rock outcroppings, which provide potential habitat for rare plants.
Thia area provides important habitat for many sensitive species, including bull trout, chinook salmon, and northern spotted owl. The Middle Fork Willamette Watershed Council has been spearheading restoration efforts in this region, to maintain and improve ecosystem function throughout the streams, rivers, wetlands, and forests.

Ecoregions

West Cascades

The West Cascades ecoregion extends from east of the Cascade Mountains summit to the foothills of the Willamette, Umpqua, and Rogue Valleys, and spans the entire length of the state of Oregon. It is largely dominated by conifer forests, moving into alpine parklands and dwarf shrubs at higher elevations.

Willamette Valley

The Willamette Valley ecoregion is bounded on the west by the Coast Range and on the east by the Cascade Range. This long mostly level alluvial plain has some scattered areas of low basalt, and contrasts with productive farmland and large urban areas. It has the fastest-growing human population in the state resulting in challenges due to land-use changes.

Key Habitats

Grasslands

Grasslands include a variety of upland grass-dominated habitats, such as upland prairies, coastal bluffs, and montane grasslands.

Late Successional Mixed Conifer Forests

Late successional mixed conifer forests provide a multi-layered tree canopy, including large-diameter trees, shade-tolerant tree species in the understory, and a high volume of dead wood, such as snags and logs.

Natural Lakes

Natural lakes are relatively large bodies of freshwater surrounded by land that were formed through geological processes, such as glacial scouring, tectonic movements, volcanic activity and river meander cutoffs. In Oregon, natural lakes are defined as standing water bodies larger than 20 acres, including some seasonal lakes. Depth is not a reference for characterization of …

Example of Oak Woodlands, which is a Strategy Habitat within the State Wildlife Action Plan

Oak Habitats

There are several oak habitat types in Oregon, where oaks comprise most of the canopy. These can include oak woodlands, oak forest, oak chaparral, and riparian oak. Oak savanna is covered in the Grasslands Key Habitat. Oaks may also co-dominate a canopy in oak/fir, oak pine, and oak hardwood habitats.

Flowing Water and Riparian Habitats

Flowing Water and Riparian Habitats include all naturally occurring flowing freshwater streams and rivers throughout Oregon as well as the adjacent riparian habitat.
