47% of Animals Caught by Idaho Wolf Trappers Are Non-Target Species.

A new public records request to Idaho Department of Fish and Game reveals that Idaho wolf trappers are capturing nearly as many non-target species as they are capturing wolves. 47% of the species captured between the 2012/2013 to 2018/2019 trapping seasons, including rare fishers, wolverine, eagle, and lynx were non-target species. Of the non-target species captured, 57% of those were killed. During the period covered by the public records response, wolf trappers killed 813 wolves, caught 620 non-target species of which 269 were released alive and 351 were killed. It is likely that a percentage of those animals that were released alive eventually died from injuries sustained from the traps that either killed them outright or made it difficult for them to find food.

The request was for “data showing capture or mortality of non-target species such as deer, elk, mountain lions, fishers, wolverines, eagles, pets, bobcat, etc. caught by wolf trappers in Idaho between the dates January 1, 2013 and December 31, 2019.”

A previous public records request in 2013 revealed similar problems with wolf and fur trappers in Idaho. That request revealed that 58% of the species captured by trappers who also had a wolf trapping permit, were non-target species.

Some of the species caught by trappers indicates that not all of the species were captured while trying to trap wolves. For example, the data reveals that two fish were killed which is probably more indicative of beaver or muskrat trapping as the cause. The public records response did not explain much about the records received.

The non-target species included bobcat (29), deer (206), dog (15), duck (21), eagle (1), elk (9), fish (2), fisher (56), goose (3), house cat (14), lion (89), lynx (1), magpie (32), marten (2), moose (10), otter (5), porcupine (8), rabbit (42), raccoon (6), raven (5), red fox (8), snowshoe hare (9), squirrel (39), Stellars jay (2), wolf (4), and wolverine (2).


The rare species caught included an eagle, 56 fishers, a lynx, and two wolverines. There is no open season for fisher, kit fox, lynx, or wolverine in Idaho. Lynx are protected under the Endangered Species Act. Additionally, fisher and wolverine have active petitions to list them under the Endangered Species Act and eagles are protected under the Bald and Golden Eagle Protection Act.

Here is the breakdown of the data:

    Superb post and documentation. Well supported in science. Thank you for your efforts.

      That is an outrage. It’s time to #BanTrapping. It’s brutal, ugly, inhumane and outdated. These trappers need to stop making a living killing our wildlife and start doing something worthwhile. This is not Management this is cruelty and ignorance…killing wolves for fun is not sport it’s just based on hate and misinformation. Let the wildlife thrive for a change and tell the ranchers and trappers to find a better way to contribute to our society than wanton killing sprees.

    And the he men trappers (maybe women too?) remain indignant and proud. I will never understand trapping of any animal except wild animals in our backyards that eat food left by ignorant homeowners. In any case, the trap should be mandated to be a non lethal trap.

  3. avatar velma Samuelson says:

    Why are wolves being trapped? Why do hunters want to get them so badly? I have been asking myself that question since the early ’70s. I don’t mind hunters shooting animals for meat. I do mind man hurting or killing to make themselves feel bigger, better or just because it is an animal. They mate for life. Trapping is worse than straight-out killing.

  4. avatar Larry Keeney says:

    You have reported this outrageous conduct that is condoned by the state before. I understand the (no I don’t understand) Republican led IDFG but what I really don’t understand is why no federal prosecutions on the threatened species. It would be interesting if the data exists to see how many hunters and fisherpeople are prosecuted for take of mistaken species ID. As far as I know in olden year’s gone by a C.O.
    Would always prosecute such happenings as: A moose shot mistaken for an elk or some other animal, bird or fish taken by mistake. Don’t the citizens of Idaho care that a small group of people get a pass on maiming protected animals that belong to all citizens?

    Incidental take with impunity. Snares are inexpensive, easy to set, and deadly for anything that gets its head inside the loop.

  6. avatar Theresa Flanigan says:

    Trapping is and will always be a cruel and unnecessary practice. I’m all for depredation on wolves when needed but by Rifle only!
    The senseless and wasteful murder of innocent animals is disgusting and I’d like to see a ban on all trapping.
    Be a man and walk into the woods with your rifle not a coward who sets a trap.

  7. avatar Dale Houston says:

    What a travesty of common sense and respect for all animals, disheartening and must be corrected.

  8. avatar KC York says:

    Thank you for all your work in obtaining this critical proof of what we know occurs in the secreted disturbing world of trapping. To think, the majority of the non-target species are self reported by trappers. How many go unreported? Trappers police themselves. Like the fox managing the hen house. What, too, of all the dependent young who perish as a result freezing, starving, exposed to the elements and predation, whether their parent is released or not? Since we have no required trap check time in Montana other than 48 hours for wolf trap sets and in designated lynx protection zones for bobcat, animals can legally be trapped for days, weeks. The evidence shows the longer the animal is trapped the greater the damage. Experts and findings provide the proof that after 24 hours the chances grow increasingly slim the animal will survive even if they are released. If the physical trapping injuries aren’t apparent the internal ones are real, i.e. capture myopathy. Wildlife rehabbers can attest to animals succumbing to this even weeks later.
    Recently, we at Trap Free Montana Public Lands, finally managed to get reporting requirements changed but there has been little word on it and equally minimal attention to it. If trapping is deemed to be highly regulated, then why wouldn’t reporting be included? It’s telling when trappers don’t want to disclose.

    Be fully aware, Montana trappers idolize Idaho. Where there is trapping there are indiscriminate victims. Traps set for wolves are monstrous and add a whole new larger to these weapons of mass destruction.

    • avatar KC York says:

      meant layer not larger.

    • avatar Liao says:

      In many states, regulation states that traps have to be checked every 24 hours, but it is very unlikely however that an animal would actually stay inside the trap for 24 hours as they are mostly active at nighttime.

      But where is the scientific evidence that after 24 hours the animal couldnt survive?

  9. avatar Ida Lupine says:

    What more can anyone say? This was to be expected once any kind of oversight was handed over to the states.

    As with most things, it is even worse than anyone could have imagined. I just hope that it doesn’t happen in the Great Lakes. As before, the last stronghold of wolves.

    • avatar Immer Treue says:

      The Great Lakes states, at least MN, allows coyote snaring. Those snares also nab incidental catch, including moose and deer.

  10. avatar C. Denise Mastroianni-Di Biasi says:

    THIS MUST STOP!!! God gave us animals for reason. These people use the animals to kill. STOP THIS!

  11. avatar kevin brown says:

    I HAVE BEEN FIGHTING THIS FIGHT AGAINST TRAPPING ALL MY LIFE AND i AM IN MY 60’S. i ALWAYS KNEW ONCE THEY GOT THEM OFF THE E.S.L. WE AND EVERY ANIMAL WERE SCREWED. mY QUESTION; WHERE ARE ALL THE GROUPS I SUPPORT THAT CLAIM TO BE TRYING TO STOP THIS. are they just ineffective. I would encourage them to join forces with their priority to end trapping. Without doing this everthing else is a lost cause. Nothing worse than a trapper.

‎"At some point we must draw a line across the ground of our home and our being, drive a spear into the land and say to the bulldozers, earthmovers, government and corporations, “thus far and no further.” If we do not, we shall later feel, instead of pride, the regret of Thoreau, that good but overly-bookish man, who wrote, near the end of his life, “If I repent of anything it is likely to be my good behaviour."
