The Ridges Sanctuary stands as one of Wisconsin’s most precious natural treasures, a place where biological diversity, ecological history, and conservation efforts converge to create an extraordinary landscape. Located on the Door Peninsula near Baileys Harbor, this sanctuary represents not only Wisconsin’s first land trust but also one of the most biologically diverse ecosystems in the Great Lakes region.
Established in 1937, The Ridges Sanctuary was born from the foresight of a small group of visionaries who recognized the ecological significance of this unique landscape. The sanctuary derives its name from the series of ridge and swale formations that characterize its topography. These ridges, formed over thousands of years as Lake Michigan’s shoreline gradually receded, create a stunning pattern of parallel sandy elevations separated by wetland swales.
What makes The Ridges extraordinary is its remarkable biodiversity. The sanctuary serves as home to over 500 plant species, including 25 species of orchids—several of which are rare or endangered. The Showy Lady’s Slipper, one of North America’s most spectacular orchids, blooms here in late spring, drawing nature enthusiasts from across the country. The varied habitats within the sanctuary—from coniferous forests and hardwood ridges to wetlands and beach dunes—support this exceptional floral diversity.
The sanctuary also provides crucial habitat for numerous wildlife species. Birds find haven among the varied ecosystems, with over 60 breeding species documented and many more passing through during migration periods. The sanctuary’s proximity to Lake Michigan creates a microclimate that supports boreal plants typically found much farther north, making it a biological crossroads where northern and southern species meet.
Beyond its ecological significance, The Ridges Sanctuary plays a vital educational role. Its nature center offers interpretive exhibits on the region’s natural history, while guided tours and workshops connect visitors with the landscape’s ecological story. Boardwalks wind through the sanctuary, providing access to its sensitive ecosystems while protecting them from foot traffic. The Range Light Boardwalk, leading to the historic Baileys Harbor Range Lights, exemplifies how the sanctuary blends natural and cultural history.
The conservation story of The Ridges remains ongoing. As development pressures increase throughout Door County, the sanctuary continues expanding its protected boundaries through land acquisition and conservation easements. Restoration efforts focus on removing invasive species and maintaining the delicate balance of this remarkable ecosystem.
The Ridges Sanctuary reminds us of the profound importance of land conservation. What began as a 40-acre parcel has grown to over 1,600 acres of protected land—a testament to the sanctuary’s founders who recognized that some places deserve protection not for their development potential but for their intrinsic natural value. In our rapidly changing world, The Ridges Sanctuary stands as a model of successful conservation and a place where people can connect with the rich tapestry of the natural world.
