 Since the woodlands surrounding the grasslands cannot be converted into grasslands, FWS will maintain them as such.The 26 acres (10 ha) of grass and shrublands within the woods, which also have become important habitat, will be allowed to return to woodland.FWS has also committed itself to exploring a number of ways to control the invasive plant species in the refuge, such as herbicides, releasing beetle and weevil species that feed on the invaders and annual prescribed burns in addition to the methods it already employs.
