About 70 miles north of St. Louis, a serene, 3,750-acre area covered in prairie grasses, forests and wetlands serves as a crucial habitat for migratory birds.
The Clarence Cannon National Wildlife Refuge in Annada sits next to the Mississippi River, surrounded by farmland. Last year, the U.S. Army Corps of Engineers and the U.S. Fish and Wildlife Service began a $29-million project to improve wildlife habitats in the refuge.
The agencies aim to bring back historic flood cycles that support native plants. They provide food and habitat for birds and other wildlife.
