White-tailed deer, wild turkey, ruffed grouse, opossum, raccoon, hawks, chipmunks, porcupine, woodpeckers, and flying, red, and eastern gray squirrels are all fairly common in the park. Black bears also inhabit Black Moshannon State Park. Many of these animals were decimated due to the effects of deforestation, pollution and unregulated hunting and trapping during the late 19th century. Hunting controls established by the Pennsylvania Game Commission and the work of the Civilian Conservation Corps and Pennsylvania Department of Conservation and Natural Resources in re-establishing the second growth forest have led to the strong comeback of game species at Black Moshannon State Park and throughout the forests of Pennsylvania.
