Mountain Lions in Colorado Episode 1: Biology & Historical Perspective

Episode 1

Colorado Parks and Wildlife’s four-part educational video series was produced to share the history of the mountain lion and the reality of living with lions in our growing state of Colorado. Episode 1 covers historical management practices, feeding behaviors, family groups, and an overview of a ten-year research project conducted by Mat Alldredge. Mat, a wildlife researcher for Colorado Parks and Wildlife who is a leading expert on mountain lions, sparked the idea to create a video series in an effort to share information on lions with the public.

“We’re trying to present our mountain lion research in an informative manner that is accessible and interesting to the public and not in a dry, boring research paper,” Mat said.

Mountain lions are a fascinating yet elusive animal, but when they do pop on the radar they make for big headlines. In Colorado, sightings of mountain lions are increasing and there have been a couple of high-profile attacks in the last two years. Thanks to sound management practices implemented over the years, mountain lions are doing quite well in Colorado. The challenge going forward will be balancing decreasing habitats and our exploding human populations.

Mountain lions are generally calm, quiet, and elusive. They tend to live in remote, primitive country with plentiful deer and adequate cover. Such conditions exist in mountain subdivisions, urban fringes, and open spaces. Recently, the number of mountain lion/human interactions has increased. This increase is likely due to a variety of reasons, such as:

  • ​More people moving into lion habitat
  • Increase in deer populations and density
  • Presumed increase in lion numbers and expanded range
  • More people using hiking and running trails in lion habitat
  • A greater awareness of the presence of lions.

If You Encounter a Mountain Lion

People rarely get more than a brief glimpse of a mountain lion in the wild. Lion attacks on people are rare, with fewer than a dozen fatalities in North America in more than 100 years. Most of the attacks were by young lions, perhaps forced out to hunt on their own and not yet living in established areas. Young lions may key in on easy prey, like pets and small children.

No studies have been done to determine what to do if you meet a lion. However, based on observations by people who have come upon lions, some patterns of behavior and response are beginning to emerge. With this in mind, the following suggestions may be helpful.

Remember: Every situation is different with respect to the lion, the terrain, the people, and their activity.

  • Go in groups when you walk or hike in mountain lion country, and make plenty of noise to reduce your chances of surprising a lion. A sturdy walking stick is a good idea; it can be used to ward off a lion. Make sure children are close to you and within your sight at all times. Talk with children about lions and teach them what to do if they meet one.
  • Do not approach a lion, especially one that is feeding or with kittens. Most mountain lions will try to avoid a confrontation. Give them a way to escape.
  • Stay calm when you come upon a lion. Talk calmly and firmly to it. Move slowly.
  • Stop or back away slowly, if you can do it safely. Running may stimulate a lion’s instinct to chase and attack. Face the lion and stand upright.
  • Do all you can to appear larger. Raise your arms. Open your jacket if you’re wearing one. If you have small children with you, protect them by picking them up so they won’t panic and run.
  • If the lion behaves aggressively, throw stones, branches or whatever you can get your hands on without crouching down or turning your back. Wave your arms slowly and speak firmly. What you want to do is convince the lion you are not prey and that you may in fact be a danger to the lion.
  • Fight back if a lion attacks you. Lions have been driven away by prey that fights back. People have fought back with rocks, sticks, caps or jackets, garden tools and their bare hands successfully. Remain standing or try to get back up!

Images and videos used in the series were collected from across the state, from both residents and within the agency. David Neils of Wild Nature Media (wildnaturemedia.com) supplied many of the fascinating videos in episode one showing mountain lions in their wild state.
