The Driftless Area (DA) was bypassed by the last continental glacier and features steep valleys, sandstone bluffs and more than 600 unique spring-fed creeks and ridges once covered in prairie and scattered oaks. This ancient landscape supports a variety of plants and animals, including dozens of uncommon species of birds of woodland and grassland habitats, reptiles and amphibians, and abundant populations of native fish found in the high concentration of cold-water streams. The DA's diversity of habitat provides critical habitat for dozens of species of concern in the State Wildlife Action Plans, and has been cited as one of North America's most important resources. Early European settlement and agricultural practices took a heavy toll on the DA, resulting in devastating erosion and serious damage to rivers. Land use practices and conservation efforts have helped heal the land, but the legacy of the past damage is still visible in the sediment-filled valleys and steep, eroding stream banks. For the past nine years Trout Unlimited's Driftless Area Restoration Effort has been working with partners to restore structural diversity, ecological function and overall health. This project will provide a new comprehensive, targeted regional approach to restoring prairie, oak woodlands and streams for the benefit of the many at-risk species and abundant concentrations of native species found in the DA landscape.
