The Great Swamp - nestled in the Harlem Valley and covering over 6,000 acres in New York's eastern Putnam and Dutchess Counties - is one of the largest freshwater wetlands in the state. It has been designated by the USDA Forest Service as a Highlands Conservation Focal Area and was cited by the state Department of Environmental Conservation in a 2009 report for its unique habitat, diverse wildlife, scenic value, and its critical function as an aquifer recharge area which protects and purifies the water supply for millions of New York residents as well as provides outstanding educational and recreational opportunities.

The Friends of the Great Swamp (FrOGS) are volunteers and neighbors who have been working to preserve the Swamp since 1990. The mission of the organization is to undertake activities to preserve, protect and promote the functions and integrity of the Great Swamp wetland and its upland watersheds in Putnam and Dutchess Counties, New York. The strength of FrOGS is the active, dedicated volunteers and citizen scientists who organize and run the activities and events, conduct the research, and speak on behalf of the Great Swamp.

Learn how YOU can become a friend of the Great Swamp through your donations and by volunteering your time.
