The Idaho House on Tuesday approved legislation allowing the state to hire private contractors and expand methods to kill wolves roaming Idaho — a measure that could cut the wolf population by 90%.

Lawmakers voted 58-11 to send the agriculture industry-backed bill to Republican Gov. Brad Little. The fast-tracked bill that allows the use of night-vision equipment to kill wolves as well as hunting from snowmobiles and all-terrain vehicles, among other measures, passed the Senate last week.

Backers said changes to Idaho law could help reduce the wolf population from about 1,500 to 150, alleviating wolf attacks on cattle, sheep and wildlife.

Opponents said the legislation threatens a 2002 wolf management plan involving the federal government that could ultimately lead to the U.S. Fish and Wildlife Service taking back control of managing the state’s wolves.

Killing 90% of the Idaho’s wolf population is not the answer
