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

Ecologist, Lead EarthWatch Scientist and good friend Cristina Eisenberg has come up for some air from her exciting field work in Alberta, Canada monitoring Wolf and Grizzly populations...........Today, Cristina shares her perspective on our most endangered Carnivore, the much admired and fondly labeled "badass", Wolverine------" Such feats as "ascending the last 4,900 feet of the highest mountain in Glacier National Park in less than 90 minutes and dispersing 500 miles across the Great Divide Basin from Yellowstone to North Dakota makes the Wolverine our toughest pound for pound carnivore in North America"--------An animal that the great departed boxer Mohamed Ali could comfortably assign his famous moniker to--"floats like a butterfly, stings like a bee".............But for all of it's prowess, the Wolverine is "a snow-dependent species standing squarely in the path of global climate change"........The female of the species requires deep and long lasting snow into Spring to successfully birth its young in snow caverns............... Christina sums up our convervation challenge for Gulo Gulo--------"This species second most important ecological need is safe passage between habitat patches"........... "National parks provide wolverine refuges"............. "But as M56 graphically demonstrated, parks are little more than postage stamps of security for a species that needs so much room to roam"

Dear Rick,

I am just back in from the field in SW Alberta where the wolves are well, as are the grizzly bears.
 . I'm in from the field for 3 weeks, then back in Alberta for more work on our project, then going to Kenya to work on an Earthwatch coexisting with lions project.
