The National Park Service conserves and manages native and exotic animal species. Urban expansion presents new and interesting challenges in wildlife management for parks in the National Capital Region (NCR). The NCR Wildlife Management Program coordinates long-term monitoring and assessment of wildlife populations. Management options for wildlife species, such as white-tailed deer and resident Canada geese, which pose threats to other natural resources, are developed through research partnerships with the Chesapeake Watershed-Cooperative Ecosystem Studies Unit (CW-CESU), US Geological Survey - Biological Resources Division (USGS-BRD), Inventory and Monitoring Program (I&M), and engagement of nonprofit organizations and the public.
