THE DECLINE OF CARIBOU ON NORTHWEST VICTORIA ISLAND 1980-93

The evidence for a decline in caribou abundance between 1980 and 1993 on northwest Victoria Island includes reports by hunters of difficulty finding caribou in the early 1990s, and aerial surveys which suggest a decline from an abundance of approximately 4000– 6000 in 1980, to 100–300 by 1993. The annual harvest as a proportion of estimated herd size increased between 1980 and 1992 to 30%. The elders of Holman also identified recent over-hunting a cause of the decline. Aerial surveys were completed during both winter and calving, which reduces the likelihood that the reduced abundance was from a shift in distribution. Evidence is inconclusive as to whether predation, competition with muskoxen or winter weather were contributing factors. A survey of local knowledge on wolves provided evidence that wolves have increased during the last decade.
