Resource Management

Fall Refuge Shot

 The refuge marks the location where the prairie meets the river and is a mosaic of large tracts of bottomland hardwood, riverine, wetland, and prairie habitat that hosts thousands of migrating birds, endangered species, fish and resident wildlife while offering the public excellent opportunities to enjoy these resources.


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.

Trapping Occurs on this Refuge

Trapping is a wildlife management tool used on some national wildlife refuges. Trapping may be used to protect endangered and threatened species or migratory birds or to control certain wildlife populations. The U.S. Fish and Wildlife Service also views trapping as a legitimate recreational and economic activity when there are harvestable surpluses of fur-bearing animals. Outside of Alaska, refuges permit trapping as a recreational use may require trappers to obtain a refuge special use permit. Signs are posted on refuges where trapping occurs. Contact the refuge manager for specific regulations. Click here for more information.

Trapping is allowed only in the Iowa River Corridor according to state regulations.  At Port Louisa National Wildlife Refuge only nuisance beaver trapping is allowed by special use permit.
