Arbor Day Foundation recognized the facility for its community forestry. On base recreation The Navy Morale Welfare and Recreation (NMWR) runs a cabin and recreation facility on Cheatham Annex. Cheatham Annex (CAX). CAX is home to the largest Morale, Welfare and Recreation (MWR) Outdoor Recreation facility on the East Coast.

Ecological footprint Endangered animals The globally rare interstitial amphipod, Stygobromus araeus, is closely associated with the groundwater in shell marl or limestone deposits. Identified in 1969 by Dr. John R. Holsinger, the 2002 DoD report on Species at Risk on DoD Installation describes this animal as 'A small, unpigmented, blind amphipod. The species is sexually dimorphic, with males ranging up to 0.70 cm in length, and females to 0.55 cm.' This extremely rare species is only found on the coast of southeastern Virginia. Environmental sites There are several sites designated on the Cheatham Annex grounds that illustrate the legacy and usage of the site over the years. The overhead view of the facility shows the sites either clustered around naval storage areas or abandoned manufacturing sites. Sites designated as "No Further Action (NFA)" sites Site 1 was used for burn residues between 1942 and 1951, and as a general landfill between 1951 and 1981. Site 1 covers approximately 2 acres and is located along the York River and behind a former incinerator that was dismantled sometime between 1989 and 1992. From 1942 to 1951 the landfill was used as a disposal area for burn residues and from 1951 to 1972 as a general landfill. A variety of wastes, including empty paint cans and paint thinner cans, cartons of ether and other unspecified drugs, railroad ties, tar paper, sawdust, rags, concrete, and lumber, were burned and disposed in the landfill until 1981. After this time, the landfill was no longer used. An estimated 15,500 tons of solid waste were buried at the landfill (this is a very crude estimate). The landfill occupies an area of approximately 1.3 acres, including a
