West-Central B.C. Caribou Research Project Annual Report March 1986	1986	The West Central B.C. Caribou Study was initiated to investigate the potential effects of logging on woodland caribou populations (Rangifer tarandus caribou) in west central B.C. Ongoing studies by MOE in both Regions 5 and 6 were expanded to include more intensive investigation of winter range and population parameters. The objectives of the study are: 1. To determine seasonal range, habitat use, and food habits of caribou. This information is necessary to develop logging prescriptions which minimize the detrimental effects of logging on caribou. 2. To determine the population size, calf production, calf survival and adult survival to evaluate the current population status and to identify major limiting factors of the caribou. Preliminary results on habitat use, population parameters and winter site investigations are presented in this report.	wsi_5955_rpt_1985-1986.pdf (1.1 MB)
West-Central B.C. Caribou Research Project Progress Report - November 1983 - June 1986	1986	Tweedsmuir Park and the area to the east has been identified as a high priority management area for woodland caribou (Rangifer tarandus caribou) (Stevenson and Hatler 1985). Two large groups of woodland caribou inhabit this area. In the north, the Tweedsmuir-Entiako caribou summer in the mountainous area of northern Tweedsmuir Park, migrate south across Tetachuck Lake and winter in the lower elevation pine and pine/spruce forests in the Entiako-Laidman Lake area. In the south, caribou summer in the ltcha-llgachuz and Rainbow mountains and winter in lower elevation pine forests in the area east and southeast of the ltcha mountains. Several groups of caribou also winter in the alpine/subalpine areas on the north side of both the Rainbow and I lgachuz mountains. Until recently, population estimates and seasonal habitat use of the woodland caribou in west-central British Columbia were primarily based on irregularly conducted population surveys and on anecdotal information. Increasing concern over current population status. habitat disturbance by logging and increased accessibility prompted the initiation of studies on radiocollared caribou. Between 1982 and 1984, caribou in both the Tweedsmuir-Entiako area and the ltcha-llgachuz-Rainbow area were radiocollared and basic information on habitat use, seasonal movements and population dynamics was collected. In April 1985, the West Central-B.C. Caribou Study was initiated to investigate the potential effects of logging on caribou in this area. The original studies were expanded to include more intensive investigation of winter range and population parameters. The objectives of the study are: 1. to determine seasonal range, habitat use, and food habits of caribou. This information is necessary to develop logging prescriptions which minimize the detrtmental effects of logging on caribou. 2. to determine population size. calf production, calf survival and adult survival so that the current population status and ...	wsi_5955_rpt_1983-1986.pdf (3.1 MB)
Working Plan - West-Central B.C. Caribou-Forestry Research Project	1986	Tweedsmuir Park and the area east of the park including the Fawnie and Itcha-Ilgachuz ranges (Fig. 1) has been identified as a high priority caribou management area in B.C. (Stevenson and Hatler 1985). This area currently supports a large caribou population (2000-3000 animals) and it is believed that the area is one of only two remaining areas in the southern half of B.C. that can sustain substantial caribou populations in the future. Although the area within the park is protected, much of the area outside of the park is scheduled to be logged. Therefore there is a need to increase our understanding of logging/caribou interactions in this area to ensure that logging activity does not threaten these caribou populations. Caribou populations have declined throughout North America as human activities encroached on their habitat (Bergerud 1974). These declines have been attributed to: 1) a reduction in winter food supplies, particularly lichens, due to habitat destruction (Edwards 1954, Bloomfield 1980), 2) overhunting, often due to improved hunter access (Bergerud 1974, Bloomfield 1980), 3) increased predation due to habitat changes which benefit wolves (Bergerud 1974, Bergerud et al. 1984) and 4) abandonment of ranges due to disturbance (Bloomfield 1980). Because all of these factors are somewhat related to logging, it is generally perceived that logging is detrimental to caribou. This perception has led to recommendations for restrictions on logging activity in caribou range (Bloomfield 1980, Bjorge 1984). There have been several studies of caribou in southeastern B.C. However the caribou in west-central B.C. belong to a different "ecotype" than the caribou in the southeast (Stevenson and Hatler 1985). Therefore it is inappropriate to extrapolate the research results from the southeastern studies to develop management guidelines for west-central B.C. The purpose of this study is to increase our understanding of caribou/forestry interactions in west ...	wsi_5955_rpt_1986.pdf (500 KB)
West-Central BC Caribou Research Project Annual Report - March 1988	1988	In April 1985, the West-Central B.C. Caribou Study was initiated to investigate the potential effects of logging on woodland caribou (Rangifer tarandus caribou) in the Tweedsmuir-Entiako and ltcha-llgachuz-Rainbow areas in west central B.C. The primary objectives of the study were to determine seasonal range, habitat use and food habits of the caribou, and to determine population size, calf production, calf survival and adult survival so that current population status and major limiting factors could be determined. The objectives were achieved through studies of radio collared caribou in the two areas. This report summarizes the results of the data collected during the third year (April 1987 March 1988) of the study.	wsi_5955_rpt_1988.pdf (2.7 MB)
West-Central B.C. Caribou Research Project Progress Report - April, 1985 - March 1988	1989	Tweedsmuir Park and the area to the east has been identified as a high priority management area for woodland caribou (Rangifer tarandus caribou) (Stevenson and Hatler 1985). Two large groups of woodland caribou inhabit this area. In the north, the Tweedsmuir-Entiako caribou summer in the mountainous area of northern Tweedsmuir Park, migrate south across Tetachuck Lake and winter in the lower elevation pine and pine/spruce forests in the Entiako-Laidman Lake area. In the south, caribou summer in the Itcha-Ilgachuz and Rainbow mountains and winter in lower elevation pine forests in the area east and southeast of the Itcha mountains. Several groups of caribou also winter in the alpine/subalpine areas on the north side of both the Rainbow and Ilgachuz mountains. Because caribou in both areas winter primarily in lower elevation forested areas, potential conflicts with logging were anticipated. Increasing concern over current population status, habitat disturbance by logging and increased accessibility prompted the initiation of studies on radiocollared caribou. Between 1982 and 1984, caribou in both the Tweedsmuir-Entiako area and the Itcha-Ilgachuz-Rainbow area were radiocollared and basic information on habitat use, seasonal movements and population dynamics was collected. In April 1985, the West Central-B.C:. Car.ibou Study was initiated to investigate the potential effects of logging on caribou in this area.
