Other small mammals that commonly are found on the refuge include eastern chipmunk ("Tamias striatus"), American red squirrel ("Tamiasciurus hudsonicus"), and eastern grey squirrel ("Sciurus carolinensis"). These species are most common in pine-oak forests where acorns are abundant. Southern flying squirrel ("Glaucomys volans") is recorded for the Upper Wells and Brave Boat divisions, but they probably also occur in other areas with mature pine-oak forest. Other small mammals that are known or are likely to occur on the refuge include hairy-tailed mole ("Parascalops breweri"), star-nosed mole ("Condylura cristata"), smoky shrew ("Sorex fumeus"), and house mouse ("Mus musculus").
