Isolated from other red squirrels since the end of the Pleistocene glacial period about 10,000 years ago, and previously thought to have gone extinct in the 1960s, the endangered Mount Graham red squirrel has worked its tail off to survive. Nestled in the upper-elevation conifer forests of southeastern Arizona's Pinaleño Mountains, this sub-species of red squirrel is territorially landlocked and highly susceptible to environmental dynamics, including wildfire and drought.
