Results of wolf (Canis lupus) control to reduce predation of cattle in northwestern Alberta are reported. Numbers of wolves declined from about 40 prior to control to 3 following the strychnine poisoning of 26 wolves during 2 winters, 1979-80 and 1980-81. Additional losses of wolf pack members occurred from natural mortality and dispersal following the removal of the majority of their packmates. In 3 of 6 instances where packs took baits, entire packs of 2, 4, and 6 wolves were killed. Ingress of wolves occurred within 1-2 years. Total mortality of cattle declined from a mean of 64 (3.4%) during 4 years prior to control to 36 (2.0%) during 2 years following control. Selectivity of strychnine poisoning was reasonably good although more emphasis on preventive management is recommended.Type
