Mountain Lion Sightings
|Mountain Lion Adult||Mountain Lion Cub|
Mountain lions generally exist where deer are found. Warning signs have been placed at walkways and gate entrances. As a precaution, the use of isolated stairs/walkways at dusk, night, or dawn is discouraged. To limit an interaction with a mountain lion, avoid hiking or jogging in the undeveloped areas of the lab alone or at dawn, dusk or night.
If you see a mountain lion, immediately call 7-911 from any Lab phone or 911 from any cell phone. Go to http://www.dfg.ca.gov/keepmewild/lion.html for more safety information from the California Department of Fish and Game.
Information for LBNL employees & guests
A few mountain lions are known to inhabit the East Bay Hills between the Caldecott Tunnel and San Pablo. While sightings are relatively infrequent, there are occasional reports of a mountain lion on the Berkeley Lab premises or the surrounding UC property. Repeated sightings in one area usually indicate that the animal is feeding on a deer carcass, which may take a week to consume.
The information on this page provides general guidance on safe practices in areas inhabited by mountain lions and humans.
Whom to call?
Call Security x6999 to report all sightings. The Security Officer will record the sighting and observe the area of the sighting. The officer will provide escort assistance to the caller's vehicle or another destination if requested. The officer will not attempt to take any action to provoke the animal. All employees should follow the guidance below on what to do or not do.
What to do and what not to do:
If you have plans to be in the hills east of the Berkeley Campus, we ask that you please be careful and keep the recent sightings in mind. If you should encounter a mountain lion, the California Department of Fish and Game suggests the following:
DO NOT HIKE ALONE: Go in groups, with adults supervising children.
KEEP CHILDREN CLOSE TO YOU: Observations of captured wild mountain lions reveal that the animals seem especially drawn to children. Keep children within your sight at all times.
DO NOT APPROACH A LION: Most mountain lions will try to avoid a confrontation. Give them a way to escape.
DO NOT RUN FROM A LION: Running may stimulate a mountain lion's instinct to chase. Instead, stand and face the animal. Make eye contact. If you have small children with you, pick them up if possible so they don't panic and run. Although it may be awkward, pick them up with out bending over or turning away from the mountain lion.
DO NOT CROUCH DOWN OR BEND OVER: A person squatting or bending over looks a lot like a four-legged prey animal. Avoid squatting, crouching or bending over, even when picking up children.
DO ALL YOU CAN TO APPEAR LARGER: Raise your arms. Open your jacket if you are wearing one. Again, pick up small children. Throw stones, branches, or whatever you can reach without crouching or turning your back. Wave your arms slowly and speak firmly in a loud voice. The idea is to convince the mountain lion that you are not prey and that you may be a danger to it.
FIGHT BACK IF ATTACKED: A hiker in Southern California used a rock to fend off a mountain lion that was attacking his son. Others have fought back successfully with sticks, caps, jackets, garden tools and their bare hands. Since a mountain lion usually tries to bite the head or neck, try to remain standing and face the attacking animal.
