Endangered Status The Mount Graham Red Squirrel, a subspecies of the Red Squirrel, is on the U.S. Endangered Species List. It is classified as endangered in Arizona, where it lives only in high-elevation spruce and fir forests in the Pinaleno (Graham) Mountains. This squirrel has declined over a century's time because of the encroachment of human activities into its environment, mainly in the form of logging and recreational development. It is also possible that the introduction of Abert's Squirrels into the region has had an affect, as the two squirrel types would have to compete for the same resources.
