Resource Management

Salt marsh habitat.

Prescribed fire and mowing with a specialized piece of forestry equipment called a “hydro-ax” is used to set back natural succession in the Shrub/Scrub habitats of the refuge. By setting back succession the refuge is able to provide different age classes of habitat to benefit a wide range of species from grassland species to ones that need mature fruit and insect-laden vegetation.

Invasive species removal is conducted in all habitat types – from phragmitites removal in the marshes to kudzu removal on the forest edge. Invasive non-native plant species tend to not be as beneficial to animals as native plant species. This is because the non-natives don’t supply the correct fruit or seed type needed by resident wildlife or the non-native species don’t supply the fruit and the correct time of year for use by our migrating species.

Habitats are monitored for productivity and condition using regionally designed inventory and monitoring protocols. Sea level rise and marsh subsidence/accretion are measured using established survey benchmarks within the marshes. Monitoring of various animal and plant species are conducted throughout the refuge to determine the carrying capacity of the habitat, the overall “health” of the habitat, the abundance of species and the effectiveness of management actions.

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.
