About the Avalonia Land Conservancy

Established in 1968 as The Mashantucket Land Trust, Inc., the organization's name was changed to Avalonia Land Conservancy, Inc. in 1995 to eliminate confusion with the Mashantucket Pequot Tribe. Avalonia refers to the region of igneous and metamorphic rock formations underlying Southeastern Connecticut. The land trust was formed originally to accept land in the towns of Groton, Ledyard, North Stonington, and Stonington. The towns of Griswold, Preston, and Voluntown joined the land trust in 1972. Sprague was added in 2007. In 1969, the land trust received its first land donation-half interest in the tip of Ram Point on Masons Island in Stonington. Since then, the land trust has acquired over 90 parcels, ranging in size from 0.5 acre of white cedar swamp to 142 acres of woodlands. Each parcel is evaluated on its own merits for acceptance by the land trust. Parcels now held by the ALC represent a wide range of diverse habitats- from salt marshes, swamps, and streams, to fields, forests, and rock ledges. Some parcels are of historic interest, containing colonial stone walls, old foundations and wells, and even a unique sheep wash in Ledyard. The ALC also owns two islands in Long Island Sound: Sandy Point, RI and South Dumpling, NY.


Avalonia's nature preserves with trails are free and open to the public from dawn to dusk. Parking is limited and only for visitors from sunrise to sunset. Unauthorized vehicles are subject to towing at the owner's expense. For more information view the Trail Maps page.
