Distribution
According to Hope et al. (2016), Tamiasciurus fremonti consists of "the Southern Rockies [of Colorado and northern New Mexico], Sacramento Mountains [of New Mexico], and Southwestern Sky Islands lineages." The authors do not mention any part of Utah as being included in the range of the species; however, the authors did not include genetic samples from southern Utah in their analysis. The current distributions of the North American Red Squirrel (Tamiasciurus hudsonicus) and T. fremonti overlap in the Southern Rocky Mountains, according to Hope et al. (2016).
Taxonomy
Tamiasciurus fremonti was split from the North American Red Squirrel (Tamiasciurus hudsonicus) by Hope et al. (2016), stating: "Through testing of competing systematic and niche-based divergence hypotheses, we recognize three species, Tamiasciurus douglasii, T. hudsonicus, and T. fremonti." According to Hope et al. (2016), they recognize Tamiasciurus fremonti as "consisting of the Southern Rockies, Sacramento Mountains, and Southwestern Sky Islands lineages and the American red squirrel, T. hudsonicus consisting of the remaining 5 lineages" that were attributed to that species.
