Caribou in the Itchas and Ilgachuz - A summary of harvest, inventory and other information 1986	1986	With the new 5 point regulation instituted in 1985, the harvest was significantly reduced. In 1983, 56 bulls were harvested; in 1984, 47. The legal harvest in 1985 was 19 with the average age being 5.0. It is expected as hunters become accustomed to the regulation and the younger bulls are afforded more protection, the age and number of bulls harvested will increase.	wsi_5955_rpt_1986.pdf (10.3 MB)
Habitat Use, Winter Feeding Ecology, and Population Status of Woodland Caribou in West-Central British Columbia	1990	Tweedsmuir Park and the area adjacent to the east supports two populations of woodland caribou (Rangifer tarandus caribou): the Tweedsmuir-Entiako population, and the ltcha-llgachuz-Rainbow population. The area was identified as a high priority management area for woodland caribou in British Columbia (Stevenson and Hatler 1985). Increasing concern over population status, winter habitat disturbance through logging and increasing accessibility, prompted the initiation of the West Central B.C. Caribou Research Project. The objectives of the study were to determine seasonal movements, habitat use and food habits of the caribou, especially during winter, and to determine population size, calf production, calf survival and adult survival to assess population status and limiting factors.	wsi_5955_rpt_1990.pdf (5.5 MB)
Population Status and Habitat Use of Woodland Caribou (Rangifer Tarandus Caribou) in the Itchas, Ilgachuz, and Rainbow Ranges, British Columbia	1996	The purpose of this document was to synthesize the existing information pertaining to the Itchas-Ilgachuz-Rainbow (Western) caribou population as of 1996. This paper was designed as a resource aid for the Regional Caribou Strategy Committee when developing an integrated management approach for caribou habitat in the Western Cariboo Region as directed by the Cariboo-Chilcotin Land-Use Plan (CCLUP).	wsi_5955_rpt_1996.pdf (2 MB)
Itcha-Ilgachuz and Rainbow Caribou Population and Habitat Information 2018	2018	The Itcha-Ilgachuz and Rainbows woodland caribou (Rangifer tarandus) herds are located on the Cariboo-Chilcotin plateau in west-central British Columbia. They are part of the southern mountain caribou population. Both caribou herds are declining, and the disturbance levels in each herds critical habitat is over federally recommended thresholds. This document provides details on the population trends, habitat conditions and habitat use for each herd.	wsi_5955_rpt_2018.pdf (848 KB)
