The forest and field communities of the park host many species of wildlife typically found in central Virginia. Baseline inventories have found 22 mammal species in the park (Pagels 2005), 13 reptile species and 17 amphibian species (Mitchell 2006), 37 fish species (Atkinson 2005) and 99 bird species (Bradshaw 2007). Understanding wildlife populations in the park is an important goal in promoting biodiversity. Each species of wildlife requires a unique combination of shelter and food requirements. For some species, seemingly minor changes in their local environment may drastically alter food or shelter availability. To promote diversity of habitats, park management efforts include such measures as invasive plant control, promoting native vegetation, and use of prescribed fire.
