Resource Management


To help plants and wildlife, refuge staff use a variety of habitat management techniques to maintain, recover or enhance plant and wildlife values. 

Characterized by bottomland hardwoods and wetlands, the refuge is managed for conservation, enhancement, and restoration of bottomland hardwoods; moist-soil management; endangered species protection; environmental education; and compatible wildlife-dependent recreation in the Lower Mississippi River Ecosystem.

The water management system at Overflow NWR allows management opportunities for any species of migratory bird using the general area. It is the discretion of the biologist/manager to design and implement the plan for emphasis on the various species in the most advantageous locations. 

The network of moist soil impoundments found within Overflow NWR are managed by refuge staff to grow native herbaceous wetland plants to support waterfowl during migration and wintering periods.  Seasonal flooding of moist soil impoundments generates favorable forage for waterfowl as they migrate south from the breeding grounds. 

Other crucial management objectives for Overflow NWR include nuisance species control of pigs and beavers.  Beavers cause major drainage issues in a bottomland hardwood environment due to their innate ability to dam running water.  These beaver dams cause flooding in stands of hardwoods trees and threaten their survival.  Refuge staff work to control beaver populations by trapping the animals and removing dams to allow the hardwood forest to drain properly. 

Feral pigs are a major concern due to their ability to destroy native habitats and consume food sources, often times out-competing native wildlife. Pigs also cause major economic damage to adjacent landowners growing agricultural crops. Refuge staff work diligently to control feral pig populations on the refuge.  

Public involvement and input are important to us and to the planning process, and we hope you will take an active interest in what the refuge does for you individually and as a community.


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. Click here for more information on trapping within the National Wildlife Refuge System.
