The Nantucket Conservation Foundation’s properties–shown on its Properties Map or posted with the Foundation’s identifying signs–are protected for scientific, educational, and conservation purposes. They are open to the public only for such recreational or other activities that are compatible with the properties’ sensitive natural systems. The Foundation is partial to pedestrians (their intrusions being least damaging) and encourages fishing, surfcasting, shellfishing (by properly licensed individuals), picnicking, scientific research, nature study, bird watching, hiking, and scenic viewing.
