Like many other natural areas in the eastern United States, the forest has a significant problem with invasive exotics, including tree-of-heaven (Ailanthus altissima), autumn olive (Eleagnus umbellata), Amur honeysuckle (Lonicera maackii), Japanese honeysuckle (Lonicera japonica), and princess tree (Paulownia tomentosa).
