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

British Columbia, Canada has just passed a law to end trophy hunts of the big bears in their Province, effective in 2018..............I am not against hunting but as so many biologists have demonstrated over the years, large carnivores like Griz regulate their own numbers..........."One hypothesis as to why this is so is that Carnivores weighing somewhere north of 29-35 pounds self regulate because of slow reproductive rates and development, extended parental care, sparsely populated territories, and a natural tendency towards infanticide, reproductive suppression, and cooperative hunting"............"Additionally, about half of these large carnivores control the numbers within their group by only letting certain members breed"............. A 2nd hypothesis regarding carnivore self regulation centers around these "hunters" being dependent on a given prey base that revolves around a minimum size territory that they can defend and call their own

 A Step in the Right Direction 

Grizzly bears have been hunted in B.C. as trophy kills for over 16 years — and for almost as long people have been asking for it to stop.
Indeed, this past February an Insights West poll found 94 per cent of British Columbians said they opposed hunting animals for sport. Since the trophy hunt restarted, about 250 grizzly bears a year have been shot dead for the fun of it.
This week, the freshly minted NDP government announced that it would ban trophy hunting in B.C. starting this November — sadly, the announcement comes too late for grizzly bears this fall as the hunting season opened Aug. 






It's tempting to break out the champagne, but as with all things coming from any level of government the small print needs to be examined.
In this case, the detail not to be overlooked is that hunters can still kill grizzly bears for food — except in the Great Bear Rain Forest, where hunting is to be totally banned.
That's all well and good — most people don't have a problem with people hunting for food.
During the election campaign, the NDP promised to stop the trophy hunt if put in power. Voters were told the plan included a provision that would still allow grizzly bear hunting but only for meat. Hunters would have to turn over any parts of the bear that could be considered trophies — so the hide, the head, paws and so on — to conservation.
At that time, the Green Party went even further saying the meat would have to be butchered and packaged and sent to the hunter's home no matter which country that was in — the hope was that this would act as a deterrent.
This week, however, Green Party leader Andrew Weaver slammed the NDP grizzly hunting-ban announcement.
"Today's announcement will not end grizzly bear hunting in B.C., as many environmental groups have advocated for," stated a Green Party media release.
"In addition, this announcement will create a system in which not all of the animal will be harvested — resident hunters will no longer be allowed to possess the hair, head and hide of grizzlies; this will be 
viewed as wasteful by the resident-hunting community.
"...Foreign hunters will still be able to shoot grizzlies in British Columbia, take a picture of themselves standing over the dead beast, and head back home without harvesting any of the animal."
The Green Party's concerns really stem from the fact that there has been no announcement about how the hunting-grizzlies-for-food plan is going to be managed and enforced. Is someone going to check to make sure that tourist hunters are flying home with their bear meat? Doubtful.
What British Columbians want is meaningful action. Is the NDP announcement welcomed? Of course it is, but voters don't want platitudes, they want action on wildlife preservation and endangered species legislation — not window dressing.
Let's remember that 30 per cent of the grizzlies killed by hunters are female — common sense tells you that in a population of 15,000 in B.C., that is too high a number.
Added to the ongoing threat our own grizzlies face are the changes south of the border thanks to U.S. President Donald Trump.
The trophy hunting industry has successfully lobbied the U.S. administration to take away federal protections on grizzlies.
In an abhorrent move Trump also recently signed into law rules allowing trophy hunters to kill grizzly bears around lures put out to attract them, to target them from aircraft, and to kill grizzly mothers and their cubs in Alaska's national wildlife refuges, where they've always been protected.
And it goes without saying that grizzly bears, like so many other species, are simply facing challenges surviving due to human encroachment on their territory and climate change impacting their environment.
The NDP announcement is welcome but more needs to be done. Let's not forget that grizzly bear viewing brings in millions of dollars in tourism — the Commercial Bear Viewing Association says that bear-viewing has become a major ecotourism revenue generator, bringing in about 10 times more than grizzly-bear hunting.
Let's hope the NDP consultation promised over the next few months produces a plan the grizzlies can live with.

Top Predators Limit Their Own Numbers

2/3/15; by 

Unlike small mammals who multiply like bunnies or some predators who’s boom or bust depends on said bunnies, large carnivores like lions and wolves keep their own numbers in check. According to a new workpublished in Oikos last week, population control is what distinguishes “apex predators” from the rest. 







Researchers have traditionally assumed that the densities of the largest of predators are determined by the availability of their prey supply, but recent studies seem to contradict a bottom-up control. And now, an international team led by Arian Wallach from Charles Darwin University proposes an alternate view: Apex predators naturally have the capacity to limit their own population densities—or self-regulate—helping to keep their ecosystems in balance.
The team tested their idea using a set of life-history traits that might contribute to self-regulation in mammalian carnivores, such as birth rate and investments by parents. They gathered research on more than a hundred species, Science reports, from skunks and stoats to polar bears, panthers, and wolves living in Yosemite. They found that an average weight of 13 to 16 kilograms (29 to 35 lbs) marks a transition between self-regulated carnivores and those that are regulated by external factors.
Small carnivores have fast rates of development and reproduction, as well as higher densities. Large carnivores, on the other hand, have slow reproductive rates and development, extended parental care, sparsely populated territories, and a natural tendency towards infanticide, reproductive suppression, and cooperative hunting, the authors write. 
About half of these large carnivores control the numbers within their group by only letting certain members breed, Science explains. Many of the bigger predators are known to have complex social systems: Dominant female wolves and hyenas, for example, kill the pups of subordinates, and in many large carnivores, the group ends up raising the alpha female’s (or pair’s) pups together. Self-regulation in large carnivores, they conclude, likely ensures that the largest and fiercest never overexploit their resources.
