Book excerpt: For nearly twenty years, alone and unarmed, author Doug Peacock traversed the rugged mountains of Montana and Wyoming tracking the magnificent grizzly. His thrilling narrative takes us into the bear's habitat, where we observe directly this majestic animal's behavior, from hunting strategies, mating patterns, and denning habits to social hierarchy and methods of communication. As Peacock tracks the bears, his story turns into a thrilling narrative about the breaking down of suspicion between man and beast in the wild.

Available in PDF, EPUB and Kindle. Book excerpt: Additionally, the 1993 federal Grizzly Bear Recovery Plan is critiqued and an alternative plan is proposed. The authors state convincingly that the greatest threat to the survival of the grizzly bear is neither a lack of firm biological knowledge nor a lack of understanding in how to apply this information. Rather, the threat lies with our politico-economic system that demands unsustainable use of our public land and water resources.

This book was released on 2006 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past 2 decades, the grizzly bear (Ursus arctos) population in the Greater Yellowstone Ecosystem (GYE) has increased in numbers and expanded in range. Understanding temporal, environmental, and spatial variables responsible for this change is useful in evaluating what likely influenced grizzly bear demographics in the GYE and where future management efforts might benefit conservation and management. We used recent data from radio-marked bears to estimate reproduction (1983-2002) and survival (1983-2001); these we combined into models to evaluate demographic vigor (lambda [k]). We explored the influence of an array of individual, temporal, and spatial covariates on demographic vigor. -- Abstract, first paragraph.

This book was released on 1985 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cumulative effects may be defined as the combined effects upon a species and its habitat resulting from multiple land uses over space and time. A Cumulative Effects Model (CEM) has been designed to (1) quantify individual and collective effects of land uses and activities in space and through time and (2) provide mangers an analytic tool for evaluating alternative decisions relative to grizzly bear recovery goals and objectives. The CEM is composed of three submodels: habitat, displacement, and mortality. The habitat and displacement submodels determine the habitat effectiveness value of an area while the mortality submodel portrays mortality risks. The submodels integrate basic variables that are significant and subject to management. The habitat submodel incorporates four variables: (1) food and thermal cover, (2) habitat diversity, (3) seasonal equity, and (4) denning suitability. These variables combined indicate the year-round habitat quality of an area. The displacement submodel includes four variables of human activity: (1) location relative to hiding cover, (2) type (motorized or nonmotorized), (3) nature (linear, point, or dispersed), and (4) intensity (high or low use, day or overnight use). Displacement is characterized by a coefficient of disturbance and by an associated zone of influence. The mortality submodel incorporates four variables of human activity: (1) location relative to habitat quality, (2) nature, (3) intensity and sanitation, and (4) firearms. By integrating the submodels, the CEM provides two basic outputs: habitat effectiveness value and mortality risk index. Once thresholds appropriate for grizzly bear recovery are established for habitat effectiveness and mortality risk, managers can manipulate the numerous variables and analyze the competitive and cumulative effects of various land uses through computer simulations.

Download or read book Night of the Grizzlies written by Jack Olsen and published by Crime Rant Books. This book was released on 1969 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: For more than half a century, grizzly bears roamed free in the national parks without causing a human fatality. Then in 1967, on a single August night, two campers were fatally mauled by enraged bears -- thus signaling the beginning of the end for America's greatest remaining land carnivore. Night of the Grizzlies, Olsen's brilliant account of another sad chapter in America's vanishing frontier, traces the causes of that tragic night: the rangers' careless disregard of established safety precautions and persistent warnings by seasoned campers that some of the bears were acting "funny"; the comforting belief that the great bears were not really dangerous -- would attack only when provoked. The popular sport that summer was to lure the bears with spotlights and leftover scraps -- in hopes of providing the tourists with a show, a close look at the great "teddy bears." Everyone came, some of the younger campers even making bold enough to sleep right in the path of the grizzlies' known route of arrival. This modern "bearbaiting" could have but one tragic result…
