TRUE GRIZZ by Douglas H. Chadwick.

The truth is that no one knows how many grizzlies are scattered through the rugged boondocks they call home on this side of the Canadian line, and it is extremely difficult and expensive to try to find out. Population totals are fashioned from collected hair samples, which provide DNA, plus smaller numbers of actual sightings subjected to large amounts of statistical massage.
Grizzlies may live thirty years or more, crisscrossing home ranges that typically encompass several hundred square miles and occasionally more than a thousand. Even the relative homebodies among them make lengthy forays as subadults dispersing from their mothers' domains. They also make strong shifts in altitude from one season to the next, rambling between thickly forested valley floors and sun-swept tundra meadows just off the peaks. And they may move to entirely new tracts as drought, wildfires, cyclical irruptions of insects, plant disease epidemics, and normal forest succession alter the habitat mix.

It has been a long time since Americas were able to homestead in vast, untamed tracts of land out West. Grizzlies no longer have that luxury either. Most parks and designated wilderness are too small to hold many such giants. Other preserves are too top-heavy; that is, they protect grand expanses of alpine scenery but end down where more fertile habitats start. Meanwhile - endangered species regulations notwithstanding - industry, real estate and mass recreation continue to extend their reach into previously remote countrysides.
What this means is that the bears have little choice but to share landscapes with us to some extent even in the best of wild-food years. Competition is inevitable and conflicts unavoidable. The question is whether they can be kept to tolerable levels. Everyone always says that the long-term solution to complex issues lies in better education. Hunt and Manley were just taking the philosophy a step farther, tutoring animals that, like us, possess a lively intelligence and inquisitive nature along with the potential for monstrous behavior.

TRUE GRIZZ by Douglas H. Chadwick.

The North Fork is a National Wild & Scenic River, and the valley that holds it is long, heavily forested, and remote. Just across the border in southeasternmost British Columbia, the upper North Fork appears to hold the thickest concentration of grizzlies yet recorded in Canada's interior. The U.S. side may harbor more grizz per square mile than anyplace else in the Lower 48.
Population density figures for this species vary dramatically from one range to the next. To me, this reinforces the notion that there is no such thing as a standard grizzly, for whenever you generalize about the animal's favorite kind of country or how often they encounter each other, you are bound to be way off for many a bear. Some tundra stretches of Alaska's North Slope and the Canadian Arctic support just one grizzly for every several hundred square miles. Yet along coastal terrain veined with streams that host a succession of salmon runs through summer and fall, biologists have recorded an average of between one and two grizzlies for each square mile. This is why even though it is still true that the great majority of occupied grizzly range lies in the continent's interior, at least half the grizzlies alive today are within about 100 miles of the Pacific. Hotspots such as Kodiak Island, the Alaska Peninsula, and Admiralty Island in the southeastern part of the forty-ninth state are the big-bear equivalents of New Delhi or teeming Hong Kong.

Asked to name America's premier grizz country outside of Alaska, many Americans would say Yellowstone. The area has about one silvertip for every twenty to forty square miles. Key sections of the North Fork host one for every five to ten square miles. The valley also supports a robust cougar population, and it was here that natural recolonization of the western United States by wolves got under way, beginning in the late 1970s and early 1980s. They share the terrain with lynx, bobcat, marten, fisher, wolverine, river otter, badger, mink, various weasels, coyote, red fox, and black bear. As ecologist John Weaver pointed out in a recent report, THe Transboundary Flathead, what emerges is a carnivore community "unmatched in North America for its variety, completeness, use of valley bottomlands, and density of species which are rare elsewhere."
