Grizzly bears, black bears, wolves, coyotes, cougars/ mountain lions,bobcats, wolverines, lynx, foxes, fishers and martens are the suite of carnivores that originally inhabited North America after the Pleistocene extinctions. This site invites research, commentary, point/counterpoint on that suite of native animals (predator and prey) that inhabited The Americas circa 1500-at the initial point of European exploration and subsequent colonization. Landscape ecology, journal accounts of explorers and frontiersmen, genetic evaluations of museum animals, peer reviewed 20th and 21st century research on various aspects of our "Wild America" as well as subjective commentary from expert and layman alike. All of the above being revealed and discussed with the underlying goal of one day seeing our Continent rewilded.....Where big enough swaths of open space exist with connective corridors to other large forest, meadow, mountain, valley, prairie, desert and chaparral wildlands.....Thereby enabling all of our historic fauna, including man, to live in a sustainable and healthy environment. - Blogger Rick

National Park Service biologist Seth Riley is the Puma expert in the Los Angeles basin where three healthy kittens were born last month............As discussed on this blog consistently, unless the California Department of Transportation comes up with the $10 million needed to create a wildlife corridor at the Lost Hills Interchange on the 101 Freeway, it is likely that in our lifetime inbreeding defects will appear in the 10 or so Pumas that call our region home-----With the concerned environmentally minded Hollywood folks that live in Los Angeles, it would seem "the folks" could easily pony up the $10 million needed to get this corridor built pronto

SoCal mountain lion cubs 

show signs of inbreeding

Scientists and ecologists celebrated the births of
three mountain lion kittens in the Santa Monica
mountains last month, but new information about
 those cubs may prove troubling.

DNA testing shows inbreeding in these new cubs, and
could pose yet another challenge for the big cats who
 face many issues surviving in close proximity to
people and one another.
Over the years, researchers have found seven
mountain lions
 that were the products of inbreeding, Seth Riley,
a wildlife
 ecologist with the National Park Service, told the
Riley says the kittens were healthy but there's
concern that
 without new blood, eventually inbreeding could
 cause physical
 defects, such as heart problems and sterility. The
 lions live in a
 patchwork of local, state and federal parkland
that stretches
westward from Los Angeles into Ventura County.
"The way mountain lion populations work is that
 all young
 males typically disperse and even half of the
young females
disperse," Riley told Take Two. "It's almost
 impossible in this
The area is surrounded by densely populated
 areas and is
 bounded by such major highways as U.S. 101,
which is heavily
 developed along most of its length. Young
 male mountain lions
that typically would seek their own territories
 have been unable
 to leave and have been killed by an older male,
 Riley said.
Only one puma, P-12, has been able to cross
the 101 freeway in
the 11 years researchers have been tracking
the animals, Riley
told Take Two. But despite bringing new DNA
 material into the
area, he sired the inbred cubs with his own
"The major issue is the fact that the 101 is
 just a development
corridor, so there's almost no place where
there's natural habitat
 next to the freeway," Riley said on Take
Two.  "They seem to be
trying to disperse, they bump right up
against development on the
 101 or they bump up against the 405...
many times they end up
 getting killed by an adult male, who they
 can't escape from, or
they get hit on the 405 or somewhere else."
A mountain lion was killed by a car on the
 101 in October 2013. 
The recreation area, state parks, the
Santa Monica Mountains
Conservancy, the California Department
 of Transportation and
others have long sought about $10 million
 in funding to create
a wildlife corridor in the Agoura Hills
 area — essentially, a tunnel
 that would allow the mountain lions
 and other animals to cross
 under U.S. 101.
