Resource Management

Fall at Great Bay - Greg Thompson/USFWS.

Habitat management focuses on grassland, wetland, shrub and forest maintenance and restoration activities. Grasslands are maintained and enhanced by prescribed burning and mowing. Wetlands are managed for migratory birds by manipulating water levels to encourage growth of aquatic vegetation. Shrub habitat is maintained by occasional mowing and thinning larger trees from certain areas. Forest management includes selective thinning of undesirable species such as black locust.

The refuge conducts several annual and intermittent wildlife surveys including waterfowl, shorebird, land bird, breeding bird, frog, vernal pool and aquatic vegetation surveys. These surveys provide baseline information that will guide the refuge in future management decisions.


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.
