Hunting is available at almost 400 national wildlife refuges, more than 35 wetland management districts and almost 20 national fish hatcheries. Hunting is a priority public use at national wildlife refuges. Wildlife hunting is subject to sustainable limits and sometimes used as a management tool to keep wildlife populations in check. Hunters' purchase of Duck Stamps helps buy conservation lands. Hunters must have an appropriate state license.
Hunting is deeply rooted in America’s heritage, and it can be an important wildlife management tool. Several laws and U.S. Fish and Wildlife Service policy permit hunting on a national wildlife refuge when it is compatible with the purposes for which the refuge was established and acquired.
