Founded in 2003, North Shore Land Alliance is an accredited Land Trust that has been instrumental in working together with land owners, municipalities and government agencies to protect 1,500 acres of conservation-worthy lands on Long Island, including the facilitation of 600 acres of local government acquisitions. The organization holds 27 conservation easements on public and private land, owns and manages 16 preserves and maintains an additional 132 acres of forest, meadows, wetlands, trails and a community garden. The Land Alliance is dedicated to educating the community about the importance of protecting land and water resources and biodiversity and how conserving land can mitigate and abate the harmful impacts of climate change.
