Resource Management

Prescribed burning and mechanical brush control are used to favor vegetation beneficial to certain species of wildlife such as the snow goose.

Water levels in the three impoundments are manipulated through water control structures and pump stations, mimicking dry and wet periods found in natural wetlands and encouraging maximum forage production, mostly in the form of submerged aquatic vegetation. Timely draw-down in early spring produces optimum conditions for migrating shorebirds while flooding in late fall produces optimum feeding areas for wintering waterfowl.

Additionally, wildlife and habitat surveys are utilized to monitor wildlife populations, including sea turtles, waterfowl, and shorebirds, and habitat health.

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.
