Wolf numbers int he Muskwa project area showed a continued increase over 1982-83. In total, wolves have increased four-fold in the Muskwa in the last six years. Very low snow accumualtions combined with incrased wolf numbers necessitated a phasing-in of wolf controlw ith only 6700 square kilometres treated in 1983-84. There were 182, or 61% of the wolves removed. Moose appear to have declined 15% this last year. Seventy-nine percent of the variation in the late winter calf recruitment is explicable by wolf numbers. Ewe mountain sheep appear to have declined 19% this lat year. Ninety-one percent of the variation in late winter lamb proportions and 100% of the variation in second year survival are explicable by wolf numbers. Caribou, constituting less than 3% of the large mammal numbers in the Muskwa, appear to be doing well. It may be that wolves at this time do not seek out this species for food. Recovery of these ungulate populations may be expected from wolf management.
