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

Overpasses and underpasses that Wildlife can traverse safely and easily are so much needed throughout the USA.............Jeez, another Puma killed on the insanely traveled 101 Freeway in Los Angeles, again right up the road from me in Agoura, California..........Disheartening as the killed "CAT" was a prospector to the area and would have infused existing female Pumas with a healthy dose of new genes,,,,,,,,,,,,,,,,,An almost "life infusion" snuffed out because all we humans ever care about are other people, never the other lifeforms that walk the planet with us

Slain Mountain Lion Would Have Brought New Genetics to Santa Monica Mountains

Of more than 30 lions tracked during the decade-long National Park Service study, only one has successfully crossed the 101 Freeway.
The lions in the Santa Monica Mountains are isolated because of freeways, mountains and the Pacific Ocean, making it crucial for new lions to be able to safely cross over into the area, according to the National Park Service.

A lion was found dead near Liberty Canyon Road on the southbound side of the freeway. According to witness reports, the lion came from the north and tried to cross lanes in the early hours of Oct. 7.

Local wildlife advocates have been lobbying for a wildlife corridor at Liberty Canyon for years.

If this lion had successfully crossed the freeway and mated, he would have brought new genetic material to the population south of the freeway, the NPS reported.

"The fact that this young male chose to cross – unsuccessfully – at Liberty Canyon shows how critical this wildlife corridor is for maintaining genetic diversity in the Santa Monica Mountains," said Dr. Seth Riley, an expert on urban wildlife with Santa Monica Mountains National Recreation Area, a unit of the National Park Service.

Caltrans has twice applied for federal transportation funding for the $10 million project, but it was not approved. Caltrans is expected to apply again in early 2014.

"This section of the 101 Freeway is the ideal path into the Santa Monica Mountains because of the natural habitat on both sides of the freeway and the connections to large areas of open space," said Riley, who has been working with the Robert Wayne Lab at UCLA and the Holly Ernest Lab at UC Davis on genetic differences in populations north and south of the 101 Freeway.

They have documented several cases of inbreeding in which a father mates with his offspring.
