Resource Management

Prescribe Burn 512x219

J. Clark Salyer staff use a variety of tools to manage Refuge lands.

To provide the widest variety of quality wetland habitat for hundreds of thousands of migratory birds, Refuge staff manage water levels to maintain everything from wet soils to deep water conditions.  This encourages growth of nutritious plants and other organisms and helps prevent cattails from over-growing the marshes.

Historically, the natural combination of wildfire and bison grazing maintained the grasslands in this area.  Today, Refuge staff use a combination of haying, grazing, mowing, prescribed burning, spraying, and biological agents to control noxious weeds and prevent the invasion of grasslands by shrubs.

In addition, some areas of the Refuge that were farmed prior to Refuge establishment are being restored back to grasslands. The restoration process begins by farming these areas again for several years.  Farming helps eliminate noxious weeds, reconditions the soil, and provides temporary food for wildlife.  Eventually, grasses are re-established on the land.


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 mammals. Outside of Alaska, refuges that 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.
