Wolves killed to lift elk numbers

UNITED STATES: Federal officials have killed 10 wolves in northern Idaho at the request of the Idaho Department of Fish and Game to boost elk numbers, and state officials say more might be killed this winter.

The US Department of Agriculture’s Wildlife Services said yesterday that workers used a helicopter in the Clearwater National Forest in late February and early March to kill the wolves.

‘‘At the request of Idaho, we did remove wolves in that region,’' said agency spokeswoman Tanya Espinosa.

Idaho officials say the area’s elk population in what is called the Lolo zone has plummeted in the last 25 years from about 16,000 to about 2000, and that wolves are to blame, along with black bears, mountain lions and a habitat transition to more forests.

Fish and Game has liberal harvest rules for bears and mountain lions, but wolves are more challenging to hunt. So in six of the last seven years, Fish and Game has sought to kill wolves to boost elk numbers.

Elk are a prominent big game species in Idaho, and hunters have decried a scarcity of them there. They are also a source of revenue through hunting licence sales for Fish and Game.

‘‘We’ve made an obligation to try to manage this elk herd at levels at maybe not peak levels, but at least bring it back to levels that we’ve seen in the past that were adequate for hunting,’' said Jim Hayden, a biologist with Fish and Game.

Officials said Fish and Game licence dollars paid for the federal agency to kill the wolves. State and federal officials did not have the cost immediately available.

Environmental groups blasted the killing of the wolves, focusing on the operation being made public only after it happened.

‘‘Now more than ever, Wildlife Services and the Idaho Department of Fish and Game need to be upfront with the public about their plans to kill wolves,’' said Andrea Santarsiere, an attorney with the Centre for Biological Diversity.

‘‘Idaho stopped monitoring wolves last year and stopped releasing annual reports revealing how many wolves remain in Idaho. It’s troubling to see this ever-increasing veil of secrecy fall over the management of Idaho’s wolves.’'

The last intensive wolf count in Idaho was in 2015, when officials said the state had an estimated 786 wolves at the end of the year. This was also the last year Fish and Game was required to do that type of count, after wolves were removed from the Endangered Species List.

But Fish and Game has continued to monitor wolf populations. Hayden said that based on DNA samples from more than 700 wolf droppings, nearly 150 remote cameras and other information, at least 11 packs were in the Lolo zone.

Fish and Game estimated that statewide, there were more than 90 wolf packs, Hayden said, far above the state’s minimum requirement of 15 packs.

He said the state and federal agencies did not announce wolf kill operations, out of concern for the safety of the helicopter crew as well as the last-minute nature of the operations. He said a snowy day had to be followed by clear flying weather.

‘‘After you go after the first one, the wolves are scattering, so it’s not common to take a whole pack,’' he said. – AP
