Strategy Habitats

Aspen Woodlands
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.

Natural Lakes
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.

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
Sagebrush habitats include all sagebrush steppe- and shrubland-dominated communities found east of the Cascade Mountains.

Wetlands
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.
