Mountain Lion Encounters
Part 1: Avoidance and Responses
Mountain Lions live throughout Yosemite, at all elevations, and in a wide array of habitat types. The chance of lion attack on humans is extremely low, compared to other threats inherent in working in the field. Fatal lion attacks have, however, occurred in the western U.S. in the last several decades. While the chance of lion attack is very low, they can be further reduced by following some simple precautions:
· Do not hike alone, especially after dark.
· Be alert and aware of your surroundings, by visually scanning along the trail ahead and behind.
If you encounter a lion:
· Remain calm. Don’t run! Lions instinctually chase running prey.
· Do not turn your back on the lion. Maintain eye contact, and stand your ground or back slowly away
· Talk to the lion in a loud, firm, confident voice.
If a lion moves toward you, does not move away, or behaves aggressively:
· Try to appear as large as possible, by holding your coat open, or raising and waving your arms.
· Stare at the lion and yell in a loud, low voice.
· If with others, stand together to give a more imposing impression.
· Arm yourself. Pick up a club-sized stick. Pelt the lion with rocks and sticks. Your goal is to convince the lion that you are not prey, and that you are a danger to it.
If a lion attacks:
· FIGHT BACK! Do not play dead! Fight as if your life depends on it, because it does.

Part 2: Interpretation of Lion Behavior - Risk and Response
The circumstances of lion encounters vary widely, but can be divided into broad categories. In each encounter, the lion’s behavior can give you an indication of its intentions, and how you should react to increase your safety.
Incidental Sightings
· Description – Sighting of lion from a distance. Lion does not stop and hold eye contact, but runs or walks out of sight. This is by far the most common type of lion sighting.
· Interpretation – Avoidance behavior. Lion being secretive.
· Risk of Attack – Low.
· Your Reaction – Make noise to keep the lion heading away. You should leave the area.
Defensive Aggression
· Description – Surprise encounter with a lion at close range. The lion reacts by hissing, snarling, and other vocalizations. Baring of teeth, ears laid back.
· Interpretation – Defensive behavior. A kill or a den with cubs could be nearby. Attack is possible.
· Risk of Attack – Moderate, depending on the distance between you and the lion, and your reaction.
· Your Reaction – Immediately back away while facing the lion and staring at it. Report the encounter to Wildlife Management or a Protection Ranger.
Predatory – Prey Assessment and Stalking
· Description – Lion stares intensely. Exhibits following and hiding behavior. The lion stays nearby and stares at you. The lion may face you or try to circle around you, generally maintaining a constant distance.
· Interpretation – Lion assessing you as potential prey, and chances of a successful attack.
· Risk of Attack – Moderate to high, depending on distance, and intensity of behavior.
· Your Reaction – Stare at the lion while making noise, and throwing rocks and sticks at the lion. Alert other people in the area. When the lion leaves, so should you, staying alert for the lion as you go. Report the encounter to Wildlife Management or a Protection Ranger.
Predatory – Pre-attack
· Description – Crouching; tail twitching; staring intensely; body low to ground; head may be up.
· Interpretation – Pre-attack.
· Risk of Attack – High.
· Your Reaction – Stare and yell at the lion; throw rocks and sticks to scare away the lion. Find a weapon, like a stick to use as a club. When the lion leaves, so should you, staying alert for the lion as you go. Report the encounter to Wildlife Management or a Protection Ranger.
Predatory – Attack Imminent
· Description – Fur fluffed out; tail twitching; body and head low to ground; rear legs pumping.
· Interpretation – Attack imminent.
· Risk of Attack – Very high and immediate.
· Your Reaction – Face and stare at the lion; yell loudly; throw rocks and sticks; find a weapon, like a fist-sized rock or club-like stick. If the lion makes contact, fight back as if your life depends on it, because it does. If you are able to repel the lion, leave the area, staying alert for the lion as you go. Report attack to a Protection Ranger.
