D&R Greenway Land Trust is central New Jersey's non-profit land preservation organization, founded in 1989. D&R Greenway permanently preserves watershed lands and large-scale landscapes, thereby preventing the loss of open space to development. The operating region consists of over 1,500 square miles, encompassing portions of the Delaware, Raritan and Millstone River watersheds and the Delaware & Raritan Canal. This includes Mercer, Hunterdon, Somerset, Middlesex, Burlington and Monmouth counties, and has broadened to include preservation of farm land in Salem County in the area of Mannington Meadows. D&R Greenway serves as the steward on many preserves and easement lands.
What sets D&R Greenway apart is the many public programs offered to connect the public with nature and inspire a conservation ethic, including art galleries at the Johnson Education Center, Second Saturday public walks, and frequent guest lectures.
