Metadata (Data about data or how the map was made)

Occurs from lowlands to alpine zones in grasslands, pastures, uncultivated fields, fence row corridors between cultivated fields, the small steep rocky patches that are found on the sides of loess slopes in the Palouse, dense mid-elevation forests, openings in the Hudsonian zone, and wet meadows and grasslands above tree line. Also found in the easternmost steppe, the Blue Mountains, the northeastern hills, and northeast Cascades.

Core zones east of the Okanogan Valley included the eastern steppe zones (the Palouse, the Blue Mountain Steppe, Canyon Grasslands, Bunchgrass/Fescue, and Big Sage/Fescue) and all forest zones of the Blue Mountains and northeastern Washington except for the Interior Western Hemlock and Interior Redcedar, which were peripheral. In the Northeast Cascades, Alpine/Parkland and Subalpine Fir were core. Good habitats in core forested zones below Alpine/Parkland were low density development, agriculture, non-forested, and open forest.
