Situated in the floodplain on the Mississippi and Iowa Rivers, resource management activities are primarily focused on providing high quality habitat for migratory birds associated with wetland habitats. Low-level dikes, water control structures, and pumps are used to mimic natural wet and dry conditions, which in turn provide food, cover, and protection to birds during their annual migrations. Other activities include planting native trees to restore flood plain forests, using prescribed fire for enhancing native grasslands, managing invasive species, and regulating public uses to provide sanctuary for migratory birds.
