Federal Ruling Puts Onus on Fish & Wildlife Service A District of Columbia federal district court judge has ruled that the U.S. Fish and Wildlife Service must examine more fully the cumulative environmental impact of hunting on 37 National Wildlife Refuges before issuing regulations that open or expand hunting opportunities on those refuges. The suit was originally filed in 2003 by anti-hunting groups seeking to thwart hunting on refuges, and several sportsman's organizations aided in the defense of the suit. One of them, the U.S. Sportsmen’s Alliance, through its Sportsmen's Legal Defense Fund, is urging the USF&WS to appeal the court's decision.
