Common species of large mammals found within the park include white-tailed deer, red fox, raccoon, woodchuck and Virginia opossum. Also present are bats, voles, mice, squirrels, skunks, and weasels. Six bat species have been identified ranging from the little Eastern pipistrels to larger bat species such as Hoary bats. A Pennsylvania species of concern, the Northern myotis, was identified through mist netting surveys in 1999. In 2004 the park was designated as an Important Mammal Area by the state of Pennsylvania because of its population of the state endangered least shrew. This is the only site in Pennsylvania where the least shrew has been documented.
