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

Will the Polar Vortex that has brought "generational" cold temperatures to the upper Midwest freeze enough ice that will allow one or more wolves to cross from Ontario to Isle Royale so as to "gene"invigorate the remaining 8 Wolves that are not currently reproducing pups?.................Satellite maps show northern Lake Superior socked in with ice.............. On Isle Royale, as late as Thursday, wolf researcher Rolf Peterson of Michigan Tech said by email that he could still see gaps in the ice and it was premature to say a bridge had formed.............. Biologists hope that will happen — the last time ice fully formed was 2008.............. The last time a wolf migrated across the ice was 1997.

Great Lakes

 have most 

ice in decades

 thanks to 

bitter winter

This winter's
have produced
 the largest
 amount of ice
 cover on the
 Great Lakes
in at least 25
Nearly 60%
 of the lakes
are now under
 a cover of ice,
 according to
the Great Lakes Environmental
Laboratory in
 Ann Arbor, Mich.
The ice cover
could help lake
 levels this
summer, but
 that is far
from certain.
 And biologists
 are keeping a
 close eye on
northern Lake
Superior in
the hope that
 an ice bridge
will link Ontario
 to Isle Royale.
The island
is the home
 to a
gray wolf
 in desperate
need of new
stock — and
more wolves.

 57% of Lake
 Superior is covered with ice.
 As the deepest of the Great
 Lakes, Leshkevich s
aid, Lake Superior takes more
sustained cold air to freeze,
and because it produces
considerable wave action
from prevailing westerly
winds, ice is slower to form.

Researcher Jay Austin of
 the University of Minnesota-
Duluth says the ice "acts like
 a giant piece of plastic" over
 the lake. That means water
can't evaporate as readily
 from sunlight.

On Isle Royale, as late as
Thursday, wolf researcher
 Rolf Peterson of Michigan
 Tech said by email that he
could still see gaps in the
 ice and it was premature
to say a bridge had formed.
Biologists hope that
 will happen — the last 
time was 2008. If ice 
from Ontario stretches
 to the island, it could 
mean the introduction
 of new wolves, which 
could help boost the
 population and diversify 
the gene pool.
The last time a wolf migrated
 across the ice was 1997.
The wolf population on the
island dropped from 16 in
2011 to eight in 2013.
In their first 2014 post from
 the island on Jan. 12,
researchers from Michigan
 Tech tracking the wolf and
moose population on the
island wrote:
"If climate projections are
accurate, only one or two
more ice bridges are likely
 before the lake is expected
 to be perpetually free of
any significant ice formation
 (by 2040.)
"Ice bridges are important
 because they represent the
possibility that a wolf can
migrate from Canada and
infuse the population with
 new genetic material —
 this appears vital for the
 population's vitality."
