The complete county distribution, spread across 3 Utah counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Utah lies at the southern edge of the Idaho pocket gopher’s range, so its 41 records fit cool northern valleys and mountain meadows rather than Grand Staircase desert. The animal spends nearly its entire life alone underground, cutting roots and digging with heavy foreclaws and incisors that close outside its lips to keep soil out.

Fan-shaped mounds are usually easier to document than the gopher itself, and winter tunneling beneath snow can leave soil casts after the melt. The submitted encounters therefore cannot define a season or population size; they chiefly identify places where deep, workable soil and herbaceous roots meet within its limited Utah range.
