Coastal Islands

© Paul Rezendes

MCHT has made remarkable progress since 1970 in conserving Maine's coastal islands: more than 275 entire islands have been protected by MCHT, thanks to the role of local, state, and federal partners and generous landowners. Our island conservation work extends along the entire coast of Maine, from the Isles of Shoals in Kittery to the wild islands of Cobscook Bay along the Canadian border, and ranges from tiny bird-nesting ledges to 4,500-acre Long Island in Blue Hill Bay, under conservation easement to Acadia National Park.

Although a vast majority of our island projects are held by partner organizations, MCHT itself owns more than 30 islands coast-wide, including Whaleboat and Malaga Islands in Casco Bay; Calderwood and Pond Islands in Penobscot Bay; Green Island, Sand Island, and Saddleback Island in Merchant Row; and Marshall Island off Mount Desert.

The outstanding natural and cultural values of these islands help define the character of Maine's coastline; additional island conservation is among the Trust's highest organizational priorities in the years ahead.
