A sandy-soil specialist

Where the plains pocket gopher will dig a range of soils, the sand hills pocket gopher is a specialist of loose, sandy ground. Named for the Nebraska Sandhills, it reaches into the sandy plains of northeastern Colorado and the sand-sheet country along the northern Front Range fringe, where older specimens from Larimer, Weld, Adams, and Washington counties trace its range. Its pale, sandy-tan coat matches that soil. Only recently split from the plains pocket gopher, it is separated as much by geography and ground type as by appearance.

A year-round life underground

Like every pocket gopher it is intensely fossorial and never hibernates, working its tunnels in all seasons. Its three recent records all date from October, far too few to show a seasonal rhythm; the animal itself is equally active and equally hidden the whole year round.

Status

NatureServe ranks the Colorado population secure. The species as a whole, though, is so recently recognized that it carries no global rank and has not been formally evaluated by the IUCN, so its wider standing is still an open question.
