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.
Through education, outreach and volunteerism, we connect people to nature and inspire a community conservation ethic.

The North Shore Land Alliance has been awarded a $1.285 million grant through the NYS Department of Environmental Conservation (DEC) Water Quality Improvement Project (WQIP) program to support the acquisition and permanent protection of nearly five acres of the Pulling property in Oyster Bay Cove.
In September 2025, the presence of laurel wilt was confirmed in Suffolk County. Laurel wilt is a disease caused by a fungus, Harringtonia lauricola, carried by the redbay ambrosia beetle (Xyleborus glabratus).
Private conservation leverages the increasing interest of the private sector to take part in conservation and allows property owners to control the destiny of their land.

Each issue features our land preservation projects, community initiatives, upcoming events and highlights of the people and partnerships that make our mission possible. It’s a great way to stay informed and inspired by the work we’re doing to protect the natural lands and waters of Long Island.
