Only 29 records exist for Merriam’s ground squirrel in Idaho, and nearly all of them land in April (17) and May (12), exactly what you’d expect from a species that spends most of the year underground. Ground squirrels emerge in spring to breed and feed, then drop into a long summer and winter dormancy, so the narrow reporting window mirrors the animal’s own biology rather than a lack of interest from observers.
Idaho also sits at the edge of this squirrel’s range. The species is centered on southeastern Oregon, and Idaho’s population is a small extension of that range rather than a stronghold. NatureServe ranks it S1, Critically Imperiled, in Idaho specifically, even though it’s more secure across its full range, a sign that this state holds only a thin, peripheral slice of the population.
Diurnal and mostly a plant-eater, it favors open, shrubby ground rather than the forest cover common elsewhere in the state.
