Wreck Island is located in a transitional zone and is one of the last large undeveloped forested islands in the outer portions of Muscongus Bay. The forest here is a mixture of deciduous and coniferous species.
This island supports nesting Bald Eagles, Osprey and a significant mixed heron rookery including nesting Great Blue Herons and Black-crowned Night-herons. Snowy Egrets also have been observed courting on the island. Several species of seabirds also nest on the island including Herring and Great Black-backed Gulls as well as Common Eider.
The primary conservation issue for Wreck Island is disturbance from recreational boating traffic including sea kayaks. Threat of an oil spill here is of concern.
Owned by the State of Maine, the Dept. of Inland Fisheries and Wildlife has management authority for Wreck Island as part of the Coast of Maine Wildlife Management Area. This island is closed to visitation from February 15 ? August 31, annually.
