Resource Management


Just off the overlook at the Ridge Trail boardwalk, volunteers plant bull rush plugs to create productive marsh habitat.

A variety of management techniques are used to promote healthy habitat throughout the refuges. Some examples of habitat conservation, management, and restoration activities on Southeast Louisiana Refuges include:  

• Bottomland hardwood restoration

• Enhancing marginal habitat with man-made structures, i.e. duck box installation

• Longleaf pine and slash pine forest restoration and nest box insert installation to benefit the endangered red-cockaded woodpecker at Big Branch Marsh NWR

• The use of prescribed fire to manage forest and marsh habitat

• Habitat protection and restoration at Breton NWR (brown pelican nesting ground habitat)

• Biological research on the Louisiana black bear at Bayou Teche NWR

• Sediment control, marsh restoration and creation at Delta NWR

• Flooding of greentree reservoirs and moist soil units at Atchafalaya NWR

• Flotant marsh construction and restoration at Mandalay NWR

• Removal of prolific invasive species which crowd out native plants (Chinese tallow tree, water paspalum, and cogon grass, etc.)

• Control of feral hogs and non-native wild boars that destroy habitat and compete for food with native wildlife

• Control of nutria in freshwater and brackish marsh habitat

• Water level and water quality management in areas where water levels have been altered by dams, flood control levees and diversion structures

• Aquatic vegetation control

• Oversight of oil and gas development and production within refuge boundaries

• Erosion control along bayous, canals, lakes, ponds and other waterways

• Use of appropriate access restrictions and enforcement of hunting, fishing, and trapping regulations


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.
