The Unicoi Mountains are coated by a primarily second-growth mixed hardwood and pine forest. Cove hardwood forests are typically found at the lower elevations along rivers and streams, and chiefly consist of yellow poplar, white oak, red oak, hemlock, and multiple other species. A mixed hardwood-pine forest covers the mountain slopes, and chiefly consists of white oak, red oak, hickory, table mountain pine, pitch pine, and shortleaf pine.
