Merriam’s kangaroo rat turns up in Utah’s warmest, sandiest corner: Washington County holds 224 of the state’s 232 records, around Red Cliffs National Monument and the surrounding desert flats, with a lone record from Coral Pink Sand Dunes State Park. That’s the Mojave Desert’s northern edge reaching into Utah, a different world from the Wasatch Front, and this kangaroo rat can survive there without ever drinking water, pulling what it needs from dry seeds.
Utah’s 232 recorded sightings show an unusual double peak: October leads with 139 records, well ahead of a smaller March bump of 39, a pattern that likely tracks seasonal survey timing more than the animal’s own activity, since this nocturnal species is rarely seen by casual visitors. Only 14 of those records came from iNaturalist photos; the rest are GBIF specimen data.
NatureServe ranks Merriam’s kangaroo rat S3, Vulnerable, in Utah, a notable status given how far north this desert specialist’s Utah range already sits from the core of its Southwestern range.
