The community lends its name to Cedarville State Forest — the state took the forest's name from the Cedarville postal address of the area — a forest of more than 3,700 acres spanning the Prince George's–Charles county line.

The state bought the first 2,631 acres for the forest in 1930 to create a forest demonstration area at the headwaters of the Zekiah Swamp, Maryland's largest freshwater swamp.

From 1933 to 1935, about 160 Civilian Conservation Corps workers, most of them African American men from Baltimore and Washington, D.C., built the forest's roads and trails and planted its pine plantations, and in the 1950s the forest operated three charcoal kilns.
