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.

Friends of the Great Swamp ( FrOGS ) is an all-volunteer not-for-profit group of friends and neighbors dedicated to preserving and protecting this unique and valuable resource through research, education, and community action.
