Gravel Island National Wildlife Refuge is a National Wildlife Refuge located off the Door Peninsula in Wisconsin. Founded in 1913, the refuge consists of two Lake Michigan islands that act as nesting grounds for native bird species. The refuge is part of the Wisconsin Islands Wilderness Area, and as such it is off-limits to the public to preserve the habitat of the islands. It is inhabited by large colonies of shore birds and waterfowl in addition to hosting a pair of great black-backed gulls, one of farthest westward breeding sites of the species.
In the years before the refuge's founding, multiple expeditions were made to the islands. Ornithologist Henry L. Ward, then-curator of the Milwaukee Public Museum, visited the area numerous times to study the herring gull populations. While visiting Gravel Island in 1906 and 1907, Ward noted very large colonies of herring gulls as well as Caspian terns while observing their behavior and collecting specimens from the island. In 1913, the refuge was formed by executive order from Gravel Island and Spider Island to protect the breeding grounds of birds living there. Upon its formation it became the 29th refuge in the United States and third in the Great Lakes region. In 1970 the refuge became part of the Wisconsin Islands Wilderness Area, one of the smallest in the country. Many studies have been performed at the refuge since the 1970s, and recent efforts have focused on tagging of the birds and studying their migration habits and breeding.
In 2009 the refuge became part of a Comprehensive Conservation Planning (CCP) program which will help manage the refuge more efficiently. The plan is intended to provide long-term continuity in refuge management, ensure that the refuge is consistent with the policies of the National Wildlife Refuge System, and improve budgets for the refuge.
