fifty types of trees, including ten species of oaks, and a rich flora of wildflowers and seventeen species of ferns and fern allies. A wide variety of animals can be seen, including bobcats, coyotes, red foxes, white-tailed deer, great blue herons and horned owls. 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). The forest is located in the Knobs region of Kentucky, also known as the Muldraugh Escarpment. This is a belt of rugged hills lying between the Bluegrass and the Pennyrile regions. The underlying geology of these hills is primarily siltstone and shale, with the siltstone creating extremely steep hillsides. The most important of these in the forest area is the Holtzclaw Siltstone, named after Holsclaw Hill.
