If you must hunt, how to better manage mountain lion populations

Posted on March 27, 2025 by Leslie

Last week I attended The Mountain Lion Conference which is held every 3 years. This is the first in-person conference since 2017 because of covid. The Conference agenda is divided between presentations from biologists discussing findings from their recent studies, and state wildlife managers giving a summary of any particular aspect of their management they might choose to present.

Most of the science presented wasn’t new to me. It’s all in my book Ghostwalker: Tracking a Mountain Lion’s Soul through Science and Story. For instance, Kyle Dougherty presented studies done on California connectivity issues, discussing how the Tehachapis are critical for genetic diversity for lions there. I did extensive interviews on connectivity and the challenges in my California chapter. One interesting note was that mountain lions in that critical corridor (where there is no highway crossing yet) spent 19.8 hours on average observing, trying to decide if and where they might cross. None of their collared cats attempted crossing the highway.

Some of the most promising studies are taking place in Texas, the only western state that still lists mountain lions as “predator” status, meaning they have no seasons and no protections. Chloe Nouzille and her crew are studying the impacts of the border wall on mountain lions and other large mammals. So far they’ve found no lions crossing the wall in places where contractors place small pass throughs. These breaks are not placed in known wildlife corridors, but randomly placed about every mile. Not all contractors are doing this. Usually it’s at the request of the landowner. What the team has found is more minimal barriers such as fences were being used by lions, although these fences are too high for deer to jump over. Another Texas study was presented by Lisanne Petracca. Her team is trying to understand the genetics of western Texas lions. Are most of these lions coming from Mexico, New Mexico, or in-breed? There haven’t been studies in Texas since 2008. This renewed attention to mountain lions is very positive and hopefully will push their state legislature to make changes in lion status.

I personally had a few takeaways from Mark Vieira’s presentation on Colorado’s mountain lion female harvest presentation. Colorado doesn’t have limits for females but like most hunting states groups together their quota for both sexes for each zone. Let’s be clear: mountain lion hunting is absolutely a choice and not necessary for lion management. Lion hunting is all about hunting opportunity, not about food. But in all our Western states except California (which outlawed lion hunting through a 1990 ballot initiative. Colorado last year rejected a similar ballot initiative which would have outlawed lion hunting) that’s a fight that is a long time out.

In the meanwhile, I strongly feel good management means a female quota. And if hunting is part of the mix, then ideally the female quota should be 0 or 1 ( where there is boot hunting). Once that limited female quota is met, the zone is shut down to female take. Mountain lions are notoriously impossible to sex unless they are treed. Even then it can be difficult but a person needs to look for a black spot below the anus indicating the lion is a male.

So what has Colorado done since they have no separate quotas? First they have included discussions with houndsmen asking them to voluntarily reduce the female harvest. Second they are now reporting the amount of females taken in live time on their quota page. Third, they require a class to learn how to identify male from a female. (try taking the I.D. exam yourself) Studies have found the difference with an identification class is 10% less killing of females and with these extra minimal efforts, Colorado has reduced their female take another 10% to 39%. Most seasoned houndsmen can distinguish male from female once a cat is treed, along with recognition of track size. States like Wyoming where I live have no required class for new or out-of-state lion hunters, and don’t have a female quota.

One other note on why mountain lion trophy states should have a female quota along with classes on lion biology—mountain lion females are either pregnant, with kittens, or in estrus. If kittens lose their mother before one year old, they almost certainly will not survive. Many states, including Wyoming, do not allow hunters to kill lions traveling with other lions (which most of the time would mean they are kittens even though kittens can be as big or bigger than mom). But females frequently stash their kittens, especially ones under six months old and many times up to one year old when they go hunting.
