The status of mountain lions is very much in question. Every day, our remaining lions are threatened by human population growth, poaching, hunting, development, pollution, and habitat loss (learn more about Active Threats to the Species). The true health of populations in the United States, Mexico, Central and South America is virtually unknown.
We don't know how many lions are left, but we do have an idea of how many we are killing. And unfortunately, that mortality number continues to grow, as lions are left with smaller and smaller patches of habitat in the West.
