Shooting wolves and bears from airplanes is once again legal in Alaska's national wildlife refuges after President Trump signed legislation to allow the hunting of predator animals.

The legislation signed Monday repeals a federal rule put in place during the Obama administration that banned the aerial shooting or baiting of animals with food in order to curb the population of bears, wolves and other predators.

Put in place by the US Fish and Wildlife Service in August 2016, the rule prohibited the hunting of predator animals unless it was authorized by a refuge manager. It also outlined specific times when the ban could be temporarily lifted in order to reduce a predator population if the decision had been evaluated and other alternatives studied.

Former Fish and Wildlife Service Director Dan Ashe, characterized the hunting tactics at the time as "a withering attack on bears and wolves that is wholly at odds with America’s long tradition of ethical, sportsmanlike, fair-chase hunting."

Alaskan lawmakers disagreed.

“Not only was it a massive jurisdictional power grab, it clearly undermined the laws passed by Congress to protect Alaska’s authority to manage fish and wildlife upon all our lands,” Alaska Rep. Don Young, a Republican, said in a statement earlier this month when the Senate passed the resolution along a party-line vote. “Alaskans take the management of our lands and wildlife extremely serious.”
