The status of the mountain lion in California evolved from that of "bountied predator" between 1907 and 1963, meaning monetary incentives were offered for every mountain lion killed, to "game mammal" in 1969, to "special protected mammal" in 1990. The change in legal status reflected growing public appreciation and concern for mountain lions.
You may live or play in mountain lion country. Like any wildlife, mountain lions can be dangerous. With a better understanding of mountain lions and their habitat, we can coexist with these magnificent animals.
WHAT SHOULD YOU DO IF YOU ENCOUNTER A MOUNTAIN LION?
There's been very little research on how to avoid mountain lion attacks. The following suggestions are based on studies of mountain lion behavior and analysis of attacks by mountain lions, tigers and leopards.
IMMEDIATELY REPORT ALL ENCOUNTERS OR ATTACKS
If you are involved in a face-to-face encounter with, or an attack by, a mountain lion, contact a ranger or the District administrative office at (650) 691-1200 as soon as possible. If it is after 5pm on a weekday or on weekends call (650) 903-6395. The threat to public safety will be assessed and appropriate action will be taken.
LIVING IN MOUNTAIN LION COUNTRY
SOME FACTS ABOUT MOUNTAIN LIONS
Physical appearance: The mountain lion, also known as cougar, panther or puma, is tawny-colored with black-tipped ears and tail. Although smaller than the jaguar, it is one of North America's largest cats.
Adult males may be more than 8 feet long, from nose to end of tail, and generally weigh between 130 and 150 pounds. Adult females can be 7 feet long and weigh between 65 and 90 pounds.
Mountain lion kittens, or cubs, are covered with blackish-brown spots and have dark rings around their tails. The markings fade as they mature.
Behavior: Mountain lions are very powerful and normally prey upon large animals, such as deer, bighorn sheep and elk. However, they can survive preying on small animals as well. They usually hunt alone, at night. They prefer to ambush their prey, often from behind. They usually kill with a powerful bite below the base of the skull, breaking the neck. They often cover the carcass with dirt, leaves or snow and may come back to feed on it over the course of a few days. Their generally secretive and solitary nature is what makes it possible for humans to live in mountain lion country without ever seeing a mountain lion.
Habitat: Mountain lions live in many different types of habitat in California, from deserts to humid coast range forests, and from sea level to 10,000 foot elevations. They generally will be most abundant in areas with plentiful deer.
Home Range: An adult male's home range often spans over 100 square miles. Females generally use smaller areas -- about 20 to 60 square miles. Along the western slope of the Sierra Nevada, where competition for habitat is intense, as many as ten adult lions occupy the same 100 square mile area.
Mortality: A mountain lion's natural life span is probably about 12 years in the wild and up to 25 years in captivity. Natural enemies include other large predators such as bears, lions and, at one time in California, wolves. They also fall victim to accidents, disease, road hazards and people.
WHEN MOUNTAIN LIONS MEET PEOPLE
Generally, mountain lions are calm, quiet and elusive. They are most commonly found in areas with plentiful prey and adequate cover. Such conditions exist in mountain subdivisions, urban fringes and open spaces. Consequently, the number of mountain lion/human interactions has increased. The increase likely is due to a variety of reasons: more people moving into mountain lion habitat, an increase in prey populations, an increase in mountain lion numbers and expanded ranges, more people using hiking and running trails in mountain lion habitat, and a greater awareness of the presence of mountain lions.
Even so, the potential for being killed or injured by a mountain lion is quite low compared to many other natural hazards. There is a far greater risk, for example, of being struck by lightning than of being attacked by a mountain lion.
