The northern extent of this COA includes the Bear Creek Buttes and Rodman Rim area in the Ochoco Mountain foothills. South of US Highway 20, the COA encompasses Pine Mountain and a large area of sagebrush steppe dotted by numerous buttes north of Christmas Valley. Heading east it covers Elk Mountain and Rams Butte before moving north again and crossing US Highway 20 near Hampton. Finally, the COA wraps around Misery Flats, the South Fork Crooked River, and into the eastern edge of Hampton Buttes.

Northern Basin and Range
The Northern Basin and Range ecoregion covers the very large southeastern portion of the state, from Burns south to the Nevada border and from the Christmas Valley east to Idaho. It is largely a high elevation desert-like area dominated by sagebrush communities and habitats.
Aspen woodlands are woodland or forest communities, dominated by aspen trees with a forb, grass, or shrub understory. Aspen woodlands can also occur within conifer forests.
Grasslands include a variety of upland grass-dominated habitats, such as upland prairies, coastal bluffs, and montane grasslands.
Natural lakes are relatively large bodies of freshwater surrounded by land. For the purposes of the Conservation Strategy, natural lakes are defined as standing water bodies larger than 20 acres, including some seasonal lakes.
Ponderosa Pine Woodlands
Ponderosa pine woodlands are dominated by ponderosa pine, but may also have lodgepole pine, western juniper, aspen, western larch, grand fir, Douglas-fir, mountain mahogany, incense cedar, sugar pine, or white fir, depending on ecoregion and site conditions. Their understories are variable combinations of shrubs, herbaceous plants, and grasses.
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.
Sagebrush habitats include all sagebrush steppe- and shrubland-dominated communities found east of the Cascade Mountains.
Wetlands are covered with water during all or part of the year. Permanently wet habitats include backwater sloughs, oxbow lakes, and marshes, while seasonally wet habitats include seasonal ponds, vernal pools, and wet prairies.
