Red Squirrels are inhabitants of mixed coniferous and spruce-fir forests in our region. Although sometimes descending into the Ponderosa Pine zone, they apparently are absent from those ranges that lack the higher elevation forests (Findley et al. 1975).

Red Squirrels today are absent south of the Sacramento Mountains of southeastern New Mexico. Their presence as fossils in the Guadalupe Mountains fits well with the vegetational evidence of subalpine forest at the southern end of the range (Van Devender et al. 1979).

There probably is no squirrel in our region during the time frame that is of this size other than Tamiasciurus hudsonicus.
