The College shares the island with the Nature Conservancy, the State of Maine, and a private summer resident. COA owns approximately 12 acres, consisting of the original light-station property, which includes the old Head Keeper’s House, two boathouses, and the actual lighthouse, which was constructed at the end of the 19th century.
Alice Eno Station
In the Summer of 2000 the station was renamed the Alice Eno Field Research Station in honor of a longstanding trustee, who dedicated enormous amounts of her time in facilitating research on the Maine coast. Cooperative agreements with TNC and the State of Maine Department of Inland Fisheries and Wildlife give COA students access to the bulk of Great Duck for sponsored research projects. Electricity at the station itself is generated by a solar array.
Great Duck supports some of the largest known breeding populations of Leach’s Storm Petrels and Black Guillemots in the Lower 48. These, along with resident Herring and Black-Backed Gulls, are subjects of on-going research by teams of students from the College’s Island Research Center under the supervision of faculty member John Anderson. Of major concern is the island’s large population of Varying Hare, a species that was introduced in the mid-20th century, and has had an enormous impact on the island’s flora.
