The primary purposes of Great Swamp Wildlife Management Area (WMA) are for wildlife management, wildlife habitat management, and wildlife-dependent recreation. This 444-acre WMA is part of the Great Swamp, a 19.8-mile long, 4,202-acre wetland of state significance and an important stopover for migrating waterfowl. While the state-owned WMA is a small part of the Great Swamp's total wetland acreage, abundant waterfowl can be found there as well as many other wildlife species.

Featured Activities

Hunting and Trapping


Wildlife Management Unit: 3G

General information on hunting and general information on trapping include how-to and safety tips with links to seasons, rules, and regulations.

Hunting opportunities at the WMA include native small game species, waterfowl, and white-tailed deer. In addition, DEC stocks pheasants in the upland area off of Cornwall Hill Road. Furbearer species found in the WMA include red and gray fox, coyote, beaver, muskrat, mink, and bobcat. Please be sure to abide by all game laws (view hunting seasons and trapping seasons).

Wildlife viewing

General information on animals includes links to information about birds, mammals, fish, reptiles, amphibians, and insects that inhabit or migrate through the state.

Large numbers of black ducks, mallards, wood ducks, and Canada geese use the Great Swamp during migration. The area also provides significant breeding habitat for wood ducks, mallards, and Canada geese during all times of year except winter, when the East Branch Croton River channel is frozen.

Other common wildlife species in the Great Swamp include game and furbearer species such as white-tailed deer, wild turkey, migratory and resident songbirds, as well as numerous turtle, snake, frog, and salamander species. Black bears and moose are occasionally observed there as well. Use the Wildlife Management Area Vertebrate Checklist (PDF) and the Wildlife Management Area Bird Checklist (PDF) as a wildlife viewing guide.

The Great Swamp Wildlife Management Area is composed of 10 separate parcels ranging from less than one acre to 300 acres in size. The largest parcel is located on Cornwall Hill Road (County Route 64), with parking available on the east side of the road about 1.5 miles south of NYS Route 311. Other large parcels are located on the east side of the East Branch of the Croton River about 0.5 miles south of Route 311 and on the east and west side of NYS Route 22 immediately south of Haviland Hollow Road. Formal access has yet to be developed in these locations.

All coordinates provided are in decimal degrees using NAD83/WGS84 datum.

How We Manage Great Swamp Wildlife Management Area

Wildlife Restoration Logo

Like most of the state's Wildlife Management Areas, Great Swamp WMA is managed by DEC's Division of Fish and Wildlife for wildlife conservation and wildlife-associated recreation (hunting, trapping, wildlife viewing, and photography). Funding to maintain and manage this site is provided by the Federal Aid in Wildlife Restoration or "Pittman-Robertson" Act, which is acquired through excise taxes on sporting arms, ammunition, and archery equipment.

Much of the management that has occurred at the Great Swamp WMA has focused on enhancing wildlife habitat, controlling invasive plant species, and improving the experience of recreational users. Recent management activities include:

  • boundary posting;
  • construction of a six-car parking area and kiosk off of Cornwall Hill Road;
  • demolition of several derelict buildings;
  • planting of native tree and shrub species including grey, silky, and red osier dogwood and white spruce;
  • reclamation of approximately 10 acres of old field at the WMA through the mechanical removal of autumn olive, a non-native, highly invasive shrub species;
  • and planting of native grass species in fields to benefit meadow-dependent wildlife species.

In addition, several volunteer groups and individuals have stewardship (Adopt-a-Natural-Resource) agreements with the Department to collect trash at the WMA parking area, mow the trails at the WMA, place bluebird and wood duck nest boxes at the WMA, and conduct an annual youth pheasant hunting day.

The protection of the Great Swamp WMA is the culmination of a larger regional effort to protect the Great Swamp's 62,343-acre watershed stretching from the Town of Dover in Dutchess County south to the Town of Southeast in Putnam County. Several organizations including the Friends of the Great Swamp (FroGS) and The Nature Conservancy, as well as Putnam County and the Town of Patterson, have worked cooperatively with DEC and the U.S. Fish and Wildlife Service (through funding from a North American Wetland Conservation Act (NAWCA) grant) to protect the Great Swamp. The Great Swamp WMA is the product of two acquisitions facilitated by the NAWCA grant, one in 2006 and the other in 2010.
