Resource Management

Resource Management 512 x 346

Upper Souris NWR is managed to benefit wildlife. This often involves using modern techniques to simulate natural processes.

To help plants and wildlife, Refuge staff uses a variety of habitat management techniques to maintain, recover and enhance plant and wildlife values. Refuge staff considers a number of management tools and employs them in varying degrees according to the situation. 

Refuge management goals include:

• conserve, protect and enhance fish, wildlife and their habitat 

• sustain and restore native prairie

• enhance waterfowl production

• promote the diversity of native species

In wetlands, the species of plants and the density of vegetation change as the wetland goes through wet and dry periods. During dry periods, wetland plants die, keeping the vegetation from becoming too thick for waterfowl. Refuge staff sometimes mow or disc wetlands to reduce vegetation and create open areas for the benefit of wildlife.  

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.
