Fish And Wildlife Service, Wisconsin.
Young black terns sit on their floating nest, a great blue heron gracefully flies over the wetland, a gentle breeze blows across the sand prairie, and a wood duck finds shelter in the bottomland forest. Welcome to Trempealeau National Wildlife Refuge! This 6,200-acre refuge lies within the Mississippi flyway, along the Mississippi River in western Wisconsin. It is an isolated backwater, cut off from the Mississippi and Trempealeau rivers by dikes, providing needed resting and feeding areas for waterfowl and other birds. The refuge is situated in a unique geological formation known as the driftless area. Thousands of years ago, glaciers surrounded but did not pass over the land. Blown into mounds, sand and silt from melting glaciers formed the rolling sand prairies of the refuge. Wetlands are a prominent feature. Before the railroads arrived and the locks and dams were built, the lands within the refuge were part of the Mississippi River. As such, these backwaters experienced floods and droughts. Today, using dikes and control structures, managers can mimic this natural cycle by lowering the water to expose mudflats and allow plants to germinate. Migratory waterfowl and marsh birds benefit.
