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

As the Interagency Grizzly Bear Research Study in the Greater Yellowstone region continues, it is now revealed that a key Fall fattening up food, the Whitebark Pine Cone Seeds are down an astounding 84% compared to last year..............As most blog readers know, the Whitebark Pine is under siege due to elevated temperatures encouraging blister wilt and other pathogens attacking the trees...............Along with the reduction of Cutthroat Trout due to competition with non-native trout, Grizzlies are seeing two historically critical foodstuffs go down the drain with the result being that it puts greater demands on the Bruins to find enough alternative protein and carb-rich foods to get them through the winter in tip top shape............Will the loss of these food staples lead to increased Bear/Man conflicts as the Bears wander far and wide to find food? .................What will the impact be to the Bears reproduction success as underweight female Bears have less success birthing and weaning cubs when underweight?

Low pinecone output means grizzly conflict more likely

The Associated Press;
JACKSON -- Biologists say a bad year for whitebark pine cone output could lead to more hunter-grizzly bear conflicts in northwest Wyoming this fall.
Officials say whitebark pine cone output has fallen off by 84 percent this year. The pine cones are an important food source for grizzlies before the winter.
Wildlife biologist Frank van Manen said the average cone count per tree dropped from 33 cones last year to just 5.2 cones per tree this year across the Greater Yellowstone ecosystem.
Because whitebarks grow at high elevations, they help keep grizzly bears separate from hunters in lower elevations.
But with the low crop, wildlife managers say there will be increased grizzly activity in the lowlands this year.
Whitebark pine has been identified by the U.S. Fish and Wildlife Service as a candidate for endangered species status. The agency says threats to the tree include habitat loss, pine blister rust, mountain pine beetle, catastrophic fire and fire suppression, environmental effects resulting from climate change, and "the inadequacy of existing regulatory mechanisms.
