The Central Cascades Crest, West COA (345 mi2) extends down the westside of the Cascade crest from Sentinel Creek down to Skookum Creek and Battle Peak. The area is partially bounded by the North Santiam River to the north, the McKenzie River to the west, the Middle Fork Willamette to the south, and the Mt Jefferson and Three Sisters Wilderness Areas to the east.

Ecoregions
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 …
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.
