Resource Management

Field vegetation

Although many factors can affect migratory birds, certain management activities that occur on this and other National Wildlife Refuges can have wide-ranging effects on the bird populations of the entire flyway.

Exotic and Invasive Plant Management
The refuge uses prescribed fire, mechanical equipment, and chemical methods to control and remove exotic and invasive plant species. The methods used depend on the plant species being controlled. Some plants require limited methods of control and others require a combination of all three methods. The ultimate goal is to control or remove exotic and invasive plant species to allow native species to regain the land.

Wetland and Moist Soil Management
Water levels are controlled manually to provide habitat for wintering waterfowl and migrating shorebirds, marsh and waterbirds. The timing and manipulation of water levels determines habitat and food availability for a variety of species.

Prescribed Fire Management
Prescribed fire is utilized as a management tool to restore and protect native habitats. The plant communities on the refuge are adapted to coexist with fire disturbances. Fire promotes the native mixed-grass prairie species and deters woody encroachment.

Farming for Wildlife
Farming provides supplemental food for a variety of wildlife species. It also acts to deter crop depredation on neighboring farm fields. Farming practices include cultivation, weed control, planting, and harvesting of remaining seed bank to use in the following year.
