REMARKABLE MOUNTAIN LIONS

The cat family, Felidae, is remarkable. The family’s smallest adults weigh less than 4 pounds, and its largest, more than 600 pounds. Our New World lion, Puma concolor, is the fourth largest cat, typically weighing under 200 pounds. Aficionados regard pumas as the “cat of cats” for their amazing combination of physical capabilities as well as utilization of habitats that range from desert to forest to swamp lands, and sea level to above 10,000 feet elevation. As obligate carnivores, cougars must eat meat because they lack enzymes to utilize plant material, and require—like all cats— several essential amino acids found only in meat. Fortunately, our lions are dietary generalists and willing to eat a wide variety of animals, and have the strength to take prey multiples more massive than themselves. This latter skill allows them to take a large animal and feed from it for several days, or longer if the weather is right. However, since these cats did not co-evolve with humans, we do not fit their “prey model,” which helps explain why fatal human interactions with mountain lions are rare.

Altogether, a mountain lion’s ability to function across a variety of landscapes and dietary choices, plus an innate aversion to people, has earned the lion a reputation as a resilient species. Indeed it is, having managed to survive persecution and extirpation attempts since shoes first touched the New World. And therein is a modern problem for lions. Wildlife agencies and hunting organizations use resilience as a keyword to disregard anthropogenic threats to our wild cats. Other than California, western states with lion populations keep increasing human-caused mortalities of lions, without regard to the loss of habitat and connectivity, drought, wildfires, and the impact of wolves returning to the west. States justify over-killing of the cats by claiming cougars are resilient and will never go extinct—unlike so many other “resilient” species have. There are more moose, more bighorn sheep, more mountain goats, than mountain lions; agencies limit hunting the former species, but kill lions willy-nilly.

Mountain Lion Foundation recognizes lion resiliency, based on conditions more than a century ago, but today’s threats are more deadly, widespread, and pervasive. The time to protect a species is before it’s endangered. At MLF, we focus on mountain lions, but we recognize that because lions are both a keystone and umbrella species, our programs also protect biodiversity and environmental integrity. Your participation and support gives MLF the resilience to carry on its fight, Saving America’s Lion.
