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

A 6 year study in Banff, Yoho and Kootenay National Parks in Northern Alberta and Waterton and Glacier National Parks in southern Alberta and Montana revealed healthy Wolverine populations...............Not large, but solid densities of "Gulos" in these two protected Park regions..............Troubling is what the research revealed in between the two Park regions---- In this unprotected region, the densities of Wolverines shrunk significantly............."The probability that a wolverine lives in an area decreases rapidly with increasing density of linear features, such as seismic lines and roads".............. "Wolverines are also impacted by climate change, as areas with persistent spring snow – believed to be important for denning – are selected by wolverines"............"These areas are being reduced as the globe warms".................The bottom line is that a larger array of natural region corridors must be created if in fact these two Park Wolverine populations are not to become genetically bottlenecked.
