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 over 1,500 acres of conservation-worthy lands in our community.

Our Core Values

Our Mission

Conserving and stewarding Long Island’s natural and historic lands, waters and environmental resources.

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

Join the Pulling Campaign to Grow Red Cote Preserve.

Join our effort to protect five irreplaceable acres of environmentally significant land in Oyster Bay Cove, NY—a once-in-a-generation opportunity to conserve open space that directly supports clean water, wildlife, and public access to nature.  We must raise $1.52 million by February 2026 to purchase the land and provide for its long-term stewardship. Every dollar you give brings us closer to preserving this vital piece of Long Island’s natural heritage forever.
