Yellow-pine chipmunk records in Utah sit entirely in the state’s northern Wasatch country, the foothills around Ogden Valley and national forest land near the Great Salt Lake, and none come from iNaturalist. Every one of Utah’s 51 records is specimen data, which is unusual for a chipmunk and suggests this population gets far less casual observation than its cousins elsewhere in the state.
Nearly every record falls in July and August, a narrow window that likely reflects short survey visits more than the chipmunk’s true active season. The bigger story is NatureServe’s ranking: this species is secure globally (G5) but listed S1, Critically Imperiled, in Utah specifically, since Utah sits at the southeastern tip of its range and the state’s population is a small, isolated fraction of a chipmunk that’s common through Washington, Idaho, and Montana.
