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

"Seismic lines, snowmobile trails, oil, gas and timber extraction and other human land altering activities fragment caribou habitat and facilitate their predator (wolf and black bear) movements(and killing success), simultaneously enhancing competition from white-tailed deer and moose".............."Restoring this altered habitat to optimum Caribou population carrying capacity is a long and drawn out affair that even when done in optimum fashion does not quickly mitigate predator impact on Caribou"............."Therefore, mitigation strategies that resist, or redirect Wolf, Bear, Deer and Moose movement where human land alteration has occurred can reduce the effects of those predators(and competing browsers) preying on Caribou".............."Therefore, by moving recreational snowmobiling trails, power lines et al. away from caribou habitat, may help draw wolves and bears away from caribou—thus, reducing those predators opportunistic killings of caribou-without the need to cull the Wolf and bear populations"

Disrupting wolf movement may be more effective at protecting caribou
