Draft legislation could move 1.1 million acres of the Desert National Wildlife Refuge from being controlled by the U.S. Fish and Wildlife Service to the U.S. Air Force. The Washington Post reports that a legislative proposal would turn more essential habitat areas into locations for training troops and testing weapons. The draft bill would stop an environmental review that has happened every 20 years and exempt the area from wildlife refuge law, which critics say would render much of the desert reserve area “a refuge in name only.” [Washington Post]
