The complete county distribution, spread across 39 Idaho counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Northern pocket gophers spend nearly their entire lives underground, using fur-lined external cheek pouches to haul roots and tubers back to a burrow system rather than eating on the surface, and the loose soils across Idaho’s public lands, from Clearwater National Forest to Massacre Rocks State Park, give them exactly the digging conditions they need. With 958 records, this is one of the best-documented small mammals in this rank range, though only 34 come from iNaturalist photographs.

Records climb sharply into a July peak, more than 165 times the February low, likely tracking when soft summer soil makes fresh mound-building easiest to spot rather than a true seasonal shift, since this species stays active underground, even tunneling through snow, all year. NatureServe rates it S4, apparently secure, statewide.
