Thomas Stone National Historic Site is located about 32 km south of Washington D.C. The site is comprised of 130 hectares of hilly lands that drain into the Hoghole Run, emptying into the Port Tobacco Creek about 1.75km south of the park boundary. Relief of the landscape is approximately 35 meters with three main drainages and numerous springs and seeps. About 100 ha are mixed forests, 20 ha fields, and 2 ha of developed area. The following is a list of current park management issues faced at the park.
- Wildlife management: Issues include a need for documentation of wildlife species composition, distribution and abundance and habitat use; need for documentation of rare, threatened, endangered and exotic wildlife species; determining effects of hunting and power line rights of way on species; deer browse monitoring
- Habitat management: Issues include a need for documentation of park vegetation species composition, distribution and abundance; a need for documentation of rare, threatened, endangered, exotic and invasive vegetative species; a need for documentation of habitat health within forested and riparian areas; determining effects of power line rights of way on species; native warm-season and meadow grass species re-introduction.
