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

We learned two weeks back that Wolverines in the lower 48 might catch a break and be put on the Endangered Speices List..............The key reason that the Federal Judge overrode the USFW previous decision not to list the GULOS is warming temperatures and the adverse impact this will likely have on female Wolverines building snow dens to birth and wean their pups...............Now, WILDLIFE CONSERVATION SOCIETY scientists are going to work up in Alaska studying this very issue---How will warming termperatures impact this Carnivore

Researchers work to better understand how climate change impacts wolverines

A team of Wildlife Conservation Society
 with the help 
of the Alaska Department of Fish and
Game, successfully
collared two North 
Slope wolverines, according to a release
 from WCS.
The team is working to understand
how climate change
affects wolverines
 and their habitat. Researchers used
high-tech traps, which
 send an email once
 it has been sprung, to capture the animals.

WCS personnel said Wolverines are hard
 to find because they are
 known to
 have a huge roaming range and make hidden
Researchers followed over 45 miles of
 wolverine tracks to learn that

 stream banks. Researchers
 only found
 one active den, and got what they say is
 the third set of images of a
mother wolverine 
and her kit.
So far, they have only been able to collar
 two wolverines. The collars
will transmit 
data every day, giving researchers a real-
time look at wolverine’s
According to WCS, the trapping portion
of the project will continue
 until the end of April


Wolverines in the lower 48 states are being
 considered for listing under
 the U.S. Endangered Species Act because
 of their low numbers and
 vulnerability to climate change. Elsewhere,
 the Committee on the 
Status of Endangered Wildlife in Canada just
 confirmed wolverine
 as a species of special concern due to its low
reproductive rate
 and susceptibility to threats such as industrial
activity and human
 access to its remote habitats via new roads
and more snowmobiles,
 which are increasing. In addition, the wolverine
is one of WCS’s 15 
global priority species. Very little is known about
 wolverines and their status 
in Alaska.

species with a

changes on the land, we need to develop a better
understanding of 
the potential magnitude of such impacts. This will be

WCS is conducting aerial surveys of wolverine tracks
on the
 North Slope of Alaska (the National Petroleum
These surveys demonstrate how wolverines are
distributed and 
how that relates to human disturbance, elevation,
and other factors. 
The survey teams, two Super Cub airplanes with a
pilot and a spotter,
 flew nearly 14,000 miles in April 2015. Future efforts
 include plans to
 live capture up to 20 wolverines in 2016 for genetic
