This report summarizes the progress of the first year of an approved 3-year program to reduce wolf numbers on Vancouver Island. The rationale for wolf control and details of program design are outlined in Janz and Hatter (1986).
Wolf densities on northern Vancouver Island have declined substantially from the levels evident in the late 1970's, due to the 70-80% decline in deer numbers resulting from wolf predation. Although wolf densities have decreased, deer numbers are still low throughout most of the north Island. Wolf densities on the south Island began to increase in the early 1980's with a consequent severe impact on many deer herds, although at present, not to the same magnitude as occurred on the north Island (Janz and Hatter 1986).
