The complete county distribution, spread across 43 Montana 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 meadow and prairie soil across Montana, from Custer National Forest to the Threemile Wildlife Management Area, gives them exactly the digging conditions they need. With 710 records, this is one of the better-documented small mammals in this rank range.

Records climb sharply into a July peak, more than 50 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 secure (S5) statewide.
