St. Martin Island, Lake Michigan

With support from our members and the Luber and Uihlein families, The Nature Conservancy protected most of the land on St. Martin Island in Lake Michigan for migrating birds and everyone who loves birds, islands and all things wild and free.

Migrating butterflies like this monarch, dragonflies and bats also use the islands. In fact, nearby Door Peninsula is one of the hottest spots for bat migration in the Great Lakes. © Gerald H. Emmerich, Jr.

The Conservancy acquired nearly 1,244 acres, or 94 percent, of the island from the Fred Luber family of Milwaukee, which has owned and cared for their land on the island since the 1980s. We purchased another 36 acres from David Uihlein, Jr. of Milwaukee. © Vin Reed

There are more than 32,000 islands in the Great Lakes. From small rocky knolls to the largest freshwater island in the world, these special places are globally unique and richly diverse. Thanks to our supporters for helping us protect St. Martin Island in Lake Michigan for migrating songbirds and everyone who is inspired by the beauty, the wildness and the magic of islands.
