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

Northern Pocket Gophers occur in meadows, grasslands, pastures, sagebrush, cultivated fields, gardens and fence rows in every county east of the Cascade crest. Found in isolated areas west of the crest where alpine and sub-alpine meadows occur. Avoids dense forest and shallow rocky soils but can be found up to 7000 feet in Washington.

Core zones included all those east of the Cascade crest, including Alpine/Parkland, plus the Willamette Valley zone. In the steppe, non-forested, forests, pasture, and soil conservation reserve fields were good habitats. In the more open forest zones, non-forested, open forest, and pastures were good habitats. Low density development was an adequate habitat in all zones.
