Friends of the Long Pond Greenbelt, celebrating its 25th anniversary in 2022, is an all-volunteer organization that works to advance the preservation, stewardship, appreciation, and enjoyment of the Long Pond Greenbelt: that unique expanse of coastal plain ponds, freshwater swamps, wetlands and woodlands encompassing more than 800 protected acres. The Long Pond Greenbelt stretches six miles between the villages of Sag Harbor and Sagaponack in the Town of Southampton on the East End of Long Island, New York.
