Abert's Squirrel- Sciurus aberti- L= 18 1/4–23 inches. Abert's Squirrels have a complicated relationship with ponderosa pine trees. Their favorite food is the cones of the Ponderosa Pine. They will turn the cone slowly, much like you may rotate an ear of corn as you eat it, peeling away the cone scales to reach the meaty seeds. The new buds and inner bark of the Ponderosa are also quickly consumed by the squirrel. You may think this would be bad for the Ponderosa; but the Abert's also eat ectomycorrhizal fungi, the consequence of this feeding activity spreads the spores of the fungi around. As it turns out this fungi is very beneficial to the survival of the Ponderosa Trees and the Abert's Squirrel serve a fundamental function in the propagation of the fungi. The relationship between the Ponderosa Pine and this little squirrel is quite remarkable and complex.
