Book Description
Weather for 1982 was normal and in most areas there was more precipitation than in 1981. A heavy spring winterkill of ungulates and adequate bear food production during the summer resulted in less grizzly bear-human conflicts in 1982 than in 1981. There were 19 grizzly bear relocations in 1982 compared to 32 in 1981. There were 30 management related grizzly bear captures, most near Cooke City and Silvergate, MT. Fewer backcountry camp problems were reported and there were no known livestock problems with grizzly bear this season. Only one grizzly bear mauling was reported this season compared to seven attacks last season. A minimum population estimate of 183 to 207 grizzly bear for 1980 has been computed from IGBS data by a special committee on population analysis. The committee calculated a slight downward trend for the Yellowstone population from 1974-1982.

Book Description
Grizzly bear sightings and sign observations were lower for 1979 in the Shoshone National Forest than in past years of the study. Other types of data indicate that bear activity in this area was not abnormally low, and some sociological or political factors that might have influenced sighting numbers are discussed. In the Bridger-Teton National Forest there were marked increases in fall sightings of grizzly bears, particularly in the Thorofare and upper Yellowstone drainages. Changes in human-use patterns may have influenced these sightings. Associated with this increased bear activity were 15 reported incidents of grizzly bears into hunting camps and two incidents of grizzlies claiming hunters? elk outside of camps. There were three known and six suspected mortalities during 1979. Two of the known and three of the suspected bear losses were associated with livestock conflicts. Present grizzly bear production ratios, when compared to periods prior to this study, indicate a slightly lower cub:female ratio but a higher yearling:female ratio. This would indicate lower grizzly bear reproduction but higher cub survival.

Book Description
During 1980 grizzly bear sightings and sign observations were only slightly above average. Observations totaled 82 for the Shoshone and Bridger-Teton National Forests, as compared to an average of 72 observations for the 1973-79 period. Observations of grizzly bears in fringe habitat or unusual areas are discussed. A continuing increase in the number of fall human-grizzly conflicts, particularly in the Thorofare and Upper Yellowstone drainages, has been documented. Camp problems with grizzly bears, some of which may have been caused by a relocated nuisance bear, were highest in the Thorofare during July and August. There were six known grizzly mortalities during 1980. All but one of these mortalities were thought to be man-caused. The young: female ratio of 2.1 cubs per female is higher than any previous year, but is based on an unduplicated sample of only 9 females and 19 cubs. A direct relationship between the number of female mortalities in one year and the number of observed females in the next year is illustrated and discussed. Analysis of sex and age data from monitored or trapped grizzly bears indicates a population heavily biased toward younger age class animals and a strong preponderance of males. A bar graph is given to illustrate age class distribution.

Book Description
American ecologists seeking to influence the founders of the National Park Service had hoped that protection of the parks would create preserves where ?natural conditions? could exist in an idealized presettlement state. These hopes, however, produced a bitter irony. In order to secure a naturally functioning park, officials had to provide intensive management to preserve ?nature at work.? For the better part of the twentieth century, the forms this management has taken have polarized public opinion. ø James A. Pritchard?s Preserving Yellowstone?s Natural Conditions demonstrates that even the most up-to-date scientific policy could not reckon with public expectations and animal behavior. When Yellowstone stopped its bear feeding program in an attempt to restore naturally regulated bear populations, the public bemoaned the loss of the spectacle. The bears, meanwhile, had learned to associate humans with food, and the loss of reliable meals brought them into campsites. Park officials had to shoot bears that made a menace of themselves, leaving many people frustrated with the park?s attempts to preserve Yellowstone as a natural ecosystem. ø Pritchard believes that restoring natural conditions for bears and other animals is a sound idea. Yellowstone, he argues, represents an ecological anchor, a relatively untrammeled slice of nature. Despite decades of tampering, the park provides scientists and managers with an outdoor laboratory for examining natural processes that existed before extensive settlement.
