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.
To help Americans better understand of the history of our nation's lethal interaction with
Puma concolor, the Mountain Lion Foundation has reposted an updated version of its
Timeline of Bounty and Sport Hunting of Mountain Lions in the U.S. This enlightening portrayal of America's persecution of the species was mentioned on the
Scientific American Magazine blog as part of its coverage of the recently published "
Cougars are recolonizing the midwest: Analysis of cougar confirmations during 1990-2008" by Michelle LaRue and
Dr. Clayton Nielsen (read our feature story) about the return of mountain lions to the Midwest after their extirpation more than a hundred years ago.

Evidence is showing most of these lions are coming from the Black Hills region which lies on the border of
Wyoming and
South Dakota. For more information about the lions that have traveled into Midwestern states, be sure to also visit MLF's
Missouri state page.
In addition, MLF is also making available, free to the public, a printed, color copy of its 11" x 17"
Where Do We Go From Here poster which can be seen at the bottom of
the timeline.
