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.

The Crawfordsville Oak-Washburn Butte COA (17 mi²) eztends from northeast of Brownsville eastward to Hwy 228. The area is primarily forested, covering the foothills north of the Calapooia River. This COA is adjacent to the Calapooia River COA.

Recommended Conservation Actions

Maintain or restore riparian and wetland habitats ecological functions and connectivity; ensure sufficient habitat complexity for wildlife.
Protect, maintain and enhance oak savanna and grassland habitats and their connection to adjacent habitats to ensure sufficient habitat complexity and connectivity for wildlife.
Remove invading conifers and non-native vegetation from oak savanna and woodlands.

Special Features

General

This area has important riparian habitat for sensitive bird species.
Area has important habitat for many oak-associated species including birds, amphibians, mammals, and plants.
Rock outcroppings support some of the last populations of western rattlesnake in the Willamette Valley.
The majority of this COA is small private parcels, which leads to potential threats from development. This makes partnerships with private landowners and partners particularly crucial in this area.
There are known mineral springs in this area, which are important habitat features providing trace minerals for band-tailed pigeons and other wildlife species.

Ecoregions

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.

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.
