I read an article recently that they ran over 500 game Cam's last year specific to counting wolves. Based off those pics they estimate the population to be over 1500. They've recently increased hunting tags to 15 per person. I think it's smart of them to want to fund a better way to track and manage wolves so they can justify killing more of them. If they don't the cattle damage claims and loss of hunter revenue in the next few years will surpass that 400k.
I fully support spending the money to track wolf numbers. IDFG must back up the need for liberal hunting and trapping seasons with the hard evidence to prove the claimed wolf numbers, otherwise the wolf activist groups might prevail in a lawsuit to stop or sharply curtail wolf hunting or trapping.
