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

Always a fun and learning weekend when Ecologist Cristina Eisenberg shares her latest Huffington Post Blog Post with us................Today Cristina focuses in on the effectiveness of Wildlife Over/Under Passes and gives us an up close and in person evaluation of how the "grandndaddy" of all culvert paradigms, the 60 wildlife highway crossings traversing Banff National Park in Canada( very busy Highway 1 slices through the Park between Canmore and Lake Louise) are preventing wildlife/auto collisions.....................Cristina(along with Dr. Anthony Clevenger, senior research scientist at the Western Transportation Institute, Montana State University) informs us that: "Initially people didn't think animals were using the crossing structures"............. "Some objected to millions of taxpayer dollars being spent in this manner".................."It is so rewarding to know that In 17 years, there has been 160,000 documented individual wildlife crossings"................."Grizzly bears prefer overpasses; cougars prefer underpasses; and wolves and moose prefer larger, more open structures"..........."It took ungulates four to five years to adapt to using the structures, it took large carnivores six to nine years"..............."Had there been Park monitoring for two years (as is common in most studies due to funding limitations), it would have been concluded that the structures weren't working for grizzly bears".................... "In Banff, this wildly successful wildlife conservation project had reduced roadkill by 80 percent for large mammals, and by 95 percent for ungulates"...............I hope that Caltrans in the Los Angeles region as well as Mary Wiesbrock of SAVE OPEN SPACE in Agoura, California will pick up on this article by Cristina and utilize it to both get the necessary funding and to install both under and overpasses at the Chesbro exit on the 101 so as to allow the dozen Pumas that still call Los Angeles home the ability to "spread their genes to other Pumas both north and south of the City of Angels

Looks like it's starting to thaw out here in Concord, MA. Spring is around the corner, although we still have 2-3 feet of hard-packed snow on the ground.

Take care,


Cristina
