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

Grizzly bears expanding their range on B.C. coast: new study


A new study in the on-line publication, PLOS ONE, has
 documented grizzlies colonizing 10 central coast islands
 outside their current accepted range, which fits with
 local aboriginal knowledge suggesting the bears are
 expanding their range.

The study's lead author, Christina Service, a University
 of Victoria PhD candidate in geography, said in an
interview Wednesday the bears were detected using
"non-invasive" methods such as remote cameras and
 hair snags from which DNA tests revealed species
, gender and individual identities, as well as hunting

Local knowledge suggests the "expansion has
accelerated over the last 10 years," the study notes.
 Among the largest of the 10 islands are Princess
 Royal, Swindle (site of the community of Klemtu),
 Campbell Island (site of Bella Bella) and Hunter.

Females and cubs, which roam less widely than
males, were discovered on four islands, raising the
 prospect of breeding populations. The findings may
cause the provincial government to extend the sort
 of habitat-conservation measures on the mainland
 to the 10 islands to protect the grizzlies, a species
of special concern,
 Service said.
Grizzlies also compete for habitat with black bears,
which could have implications for the white-phase
Spirit Bear.

Theories behind the shift in grizzlies include a drop in
 salmon production since 2000, movements to exploit
 berries in recent clearcuts on islands, as well as
reduced hunting of grizzlies on the mainland.

Other study participants included the Kitasoo/
Xai'xais-operated Spirit Bear Research
Foundation and Raincoast Conservation Foundation.
