[2] Patuxent Research Refuge supports a wide diversity of wildlife in forest, meadow, and wetland habitats.

The land is managed to maintain biological diversity and to protect and benefit native and migratory bird species.

Increasing forest fragmentation in the area caused by urban development has damaged many populations of neotropical migratory birds.

[1] Patuxent Research Refuge is divided into three areas: 1) North Tract, which offers hunting, fishing, wildlife observation, trails, and many interpretive programs; 2) Central Tract, where the headquarters for both the refuge and the USGS Patuxent Wildlife Research Center are located, as well as research study sites; and 3) South Tract, which has the National Wildlife Visitor Center, trails, and many educational programs.
