Recent Mountain Lion sightings along the Boise River mean more of us need to be educated about living with these large predators.
Mountain lions can be found throughout Idaho, including the City of Boise. It is important to keep wildlife wild and remove whatever is attracting mountain lions. If people are regularly seeing a lion in a particular area, it may mean the lion represents a public safety risk. For more on recent sightings, click on Boise Police News Release, Oct. 5, 2012
Because mountain lions are shy and elusive, people do not often see them. However, according to Idaho Fish & Game wildlife managers, mountain lions frequently move through urban areas of the Treasure Valley.
The following information is taken from the State of Arizona Game and Fish Department:
Mountain lions are solitary animals with the exception of females with kittens or breeding pairs. Signs of mountain lion presence include large tracks (3-5 inches wide) without claw marks; large segmented, cylindrical droppings; food caches where a kill has been partially eaten and then covered with leaves, brush or dirt; and scrapes in soft dirt or leaf litter.
Description and Habits
- Tan or reddish brown to dusky or slate gray coat; young have numerous black spots that mostly disappear with age
- Long tail that is about 2/3 of body length, white underneath with a dark brown or black tip
- 70-150 pounds (males usually larger than females)
- 25-32 inches tall at the shoulder (similar to a German shepherd dog)
- 5 ½ to more than 8 feet long
- Average litter of three kittens, which are yellowish-brown with black spots
- Kittens stay with mother for approximately 18 months
- Live up to 13 years in wild with average of less than 6 years
- Can jump 20 feet vertically and 40 feet horizontally in a single leap
- Rarely make vocal noises, unless during breeding season or when threatened
- Territory sizes range from 10 to 150 square miles; males range more widely than females
- Diet is primarily deer, but also includes javelina, bighorn sheep, elk, small mammals and occasional depredation on livestock and pets
Possible Conflicts with Humans and Pets
Urban sprawl often results in shrinking habitat and increases the number of conflicts between humans and wildlife, such as mountain lions. Conflicts can occur when a mountain lion becomes too accustomed to the presence of people, often near where we live or recreate, and begin preying on livestock or other domestic animals. Although uncommon, mountain lion attacks on humans occasionally occur.
What Attracts Them?
Mountain lions most often pass through human-occupied space, but may stay longer if they have access to food, water, or shelter.
- Food sources found near people’s homes includes deer, javelina, rabbits, unsecured domestic animals, or livestock.
- Water for drinking can include a swimming pool, fountain, pond, or pet’s water bowl.
- Mountain lions might use “cave-like” areas beneath sheds, unused buildings, and storm drains, or elevated wooden patios, for shelter.
Other factors that may contribute to mountain lions presence around humans include:
- Drought - Wildlife will come into urban fringe areas to search for food and water.
- Wildfires - Wildfires damage vital habitat and force animals into new areas.
- Habituation to humans through close contact, exposure, and increased development near wildlife habitat.
Humans feeding mountain lion prey (like javelina or deer), having livestock adjacent to wildlife habitat, and related activities create familiarity and habituation to humans.
What Should I Do?
Mountain lions are predators capable of seriously injuring or killing humans. The risk of attack by a mountain lion is small, but real; children are most at risk. Mountain lions may return repeatedly if food, water, or shelter is available. However, mountain lions use natural areas, such as washes, to move through populated areas to more remote areas, and such movements are necessary to prevent problems with inbreeding and local extinction associated with habitat fragmentation. If food, water, and shelter are not available, mountain lions generally move on to other areas more quickly. If you live or recreate in lion country, remain aware of your surroundings and take steps to minimize risks to yourself, your family, and pets.
If you encounter a mountain lion:
- Do not approach the animal. Most mountain lions will try to avoid a confrontation. Give them a way to escape.
- Stay calm and speak loudly and firmly.
- Do not run from a mountain lion. Running may stimulate a mountain lion’s instinct to chase.
- Stand and face the animal. Make eye contact.
- Appear larger by raising your arms or opening your jacket if you are wearing one. Throw stones, branches, or whatever you can reach without crouching or turning your back. Wave your arms slowly. The idea is to convince the lion that you are not easy prey and that you may be a danger to it.
- Maintain eye contact and slowly back away toward a building, vehicle, or busy area.
- Protect small children so they won’t panic and run.
- Fight back if attacked. Many potential victims have fought back successfully with rocks, sticks, caps, jackets, garden tools, their bare hands, and even mountain bikes. Since a mountain lion usually tries to bite the head or neck, try to remain standing and face the animal.
Report all mountain lion attacks to 911. All mountain lion encounters and attacks, sightings in urban areas, property damage due to mountain lions or possession of a live mountain lion should also be reported to your regional Idaho Fish & Game office. In the Treasure Valley, our regional office is in Nampa: (208) 465-8465.
Boise Police work closely with Idaho Fish & Game to help people learn how to live safely in proximity to mountain lions, and to remove animals that are a potential threat to the public.
If you live in mountain lion country, you should:
- Hike or walk in groups.
- Make noise when you’re outside.
- Closely supervise children whenever they play outdoors, especially in rugged country between dusk and dawn. Talk with children about mountain lions and teach them what to do if they encounter one.
- Keep dogs, cats, poultry, sheep, goats, rabbits, rodents and other domestic animals indoors or in a secure enclosure with a sturdy roof. Always walk pets on a leash. Roaming pets are easy prey for hungry mountain lions and coyotes. Do not feed pets outside and keep their food inside; the food can attract javelina and other mountain lion prey.
- Avoid feeding wildlife. By feeding deer, javelina, or other wildlife in your yard, you may inadvertently attract mountain lions, which prey upon them.
- Trim landscaping around your home. Remove dense and low-lying vegetation that can provide good hiding places for mountain lions and coyotes, especially around children’s play areas.
- Install outdoor lighting. Keep the house perimeter well lit at night, especially along walkways, to keep any approaching lions visible.
