![]() Green Bay National Wildlife Refuge Green Bay National Wildlife Refuge consists of Hog Island (2 Acres), Plum Island (325 Acres), and Pilot Island (3.7 Acres). The islands are located in Lake Michigan, near Washington Island, off the tip of Wisconsin’s Door Peninsula. Hog Island was set aside by Executive Order in 1913 as a preserve and breeding ground for native birds. Plum and Pilot Island were transferred from the U.S. Coast Guard to the Fish and Wildlife Service in 2007. The islands were acquired to protect native bird habitat and endangered species habitat in the Great Lakes Basin Ecosystem. The refuge is managed by staff at Horicon National Wildlife Refuge, in Mayville, WI. Hog Island supports a nesting colony of herring gulls and a few nesting great blue herons and red-breasted mergansers. No development has occurred on Hog Island due to its small size, remoteness, and landing difficulties. Portions of Plum and Pilot Islands were developed to serve as lighthouse facilities or life saving stations during the late 19th century. Plum Island essentially functions as a small ecosystem and retains natural qualities absent on the nearby mainland. Today Pilot Island supports nesting colonies of double-crested cormorants, and herring gulls. A handful of great blue and black-crowned night herons also nest on Pilot Island. All public use is prohibited on Hog and Pilot Islands due to ground nesting by migratory birds and the limited and treacherous access. Plum Island may offer public use opportunities in the future provided they are compatible with the refuge’s purpose and mission.
