18、andus caribou) ecotypes, mountain and northern, were translocated to the southern Selkirk Mountains in northern Idaho (U.S.A) to augment a remnant subpopulation. The translocation resulted in an additional subpopulation that used the general area of the release site. The mountain ecotype stock exhib

19、ited patterns of movement and habitat use similar to those of the resident subpopulation. The northern ecotype stock exhibited more variable habitat use, especially in the first year after translocation. Dispersal of the northern stock was not as extensive as that of the mountain stock. Fourteen of

20、22 caribou from the northern stock and 6 of 18 caribou from the mountain stock died during the 3-year period after the release. Our results suggest that when donor subpopulations must be used that do not closely compare with resident subpopulations extinct or extant, larger numbers of individuals ma

We investigated the relative spatial and temporal changes in range use and mortality within the Red Wine Mountains caribou herd, a popu

23、lation that declined by approximately 75% from the 1980s to the 1990s. To extract the spatial structure of the population, we applied fuzzy cluster analysis, a method which assigns graded group membership, to space use of radio-tracked adult females, and compared these results to a hard classificati

24、on based on sums-of-squares agglomerative clustering. Both approaches revealed four subpopulations. Based on the subpopulation assignments, we apportioned the number of animals, radio-days, calving events and mortalities across subpopulations before and after the decline. The results indicated that,

25、 as the herd declined, subpopulations were disproportionately affected. In general, subpopulations with the greatest range overlap with migratory caribou from the George River herd experienced comparative reductions in activity and increased mortality. The subpopulation with the least overlap exhibi

26、ted the converse pattern. The infra-population imbalances were more pronounced when herd clustering was employed. Our results reiterate that refugia from other ungulates may be important in the persistence of taiga-dwelling caribou. We propose that changes across time and space are valuable assays o

28、f: 44We attempted to develop a model to quantify factors affecting visibility of woodland caribou and provide statistically valid population estimates. Our design consisted of a 2-stage sampling effort: a pre-census fixed wing flight to determine caribou distribution and a census flight using a heli

29、copter to count and classify individuals. Radio-marked caribou were used to quantify conditions of non-detection. We detected 100% of the groups with at least 1 radio-marked caribou during the fixed-wing flights (n=27). Eighty-three percent (23 of 27) of these groups were detected during the helicop

30、ter census. The conditional probability of detecting a group during the census was ) 0.81 at the 90% confidence level. The minimum population size was determined to be 47, 47, 51 and 45 in 1991-1994. Modeling the detection factors had limited value for the highly successful technique described here.

33、Woodland caribou (Rangifer tarandus caribou) in southeastern British Columbia feed on arboreal lichen during the winter that are most abundant on old trees and thus have been identified as an old-growth dependent species (B.C. Ministry of Environment 1989). Clear-cut harvesting of mature forests has

34、 been perceived as being incompatible with maintaining winter habitat for caribou. The relationship between the amount of clearcutting plus other forms of human intrusion into caribou habitat and actual numbers of caribou is unknown. To develop an understanding of this relationship, the number of ca

35、ribou must be known and we must have the ability to track their numbers as the condition of their habitat changes. The primary purpose of this report is to present information on a caribou census conducted in March 1994. It is hoped that this census can be used as a benchmark for future censuses. In

36、 addition, we summarized caribou censuses conducted in this area in 1993, and others conducted in the past by the B.C.

45、 mountain caribou near the southernmost extension of their range. This ecotype is dependent upon late-successional forests, largely because such stands provide arboreal lichen for winter forage. Recent provincial forest practices legislation and land-use planning initiatives have provided the impetu

46、s for developing an interim caribou habitat assessment model for use as a planning tool. We applied the HIS (habitat suitability index) model developed for a nearby population as a testable hypothesis of caribou habitat selection in the southern Purcells. In a study area of about 6000km2, 512 radiol

47、ocations were obtained for 22 animals from 1993 through 1995. Seasonal selectivity was assessed for the following model variables: elevation, slope, habitat type/current cover type, over story size class, canopy closure, and age of dominant over story. Caribou were most selective for stand age, whic

48、h the model also defined as the greatest determinant of habitat suitability. However, we did not judge overall model output to be an adequate predictor of habitat selection by southern Purcell caribou. Seasonal ratings for each variable were therefore modified to better reflect selection patterns by animals
