The B.C. government killed 237 wolves as part of its wolf cull program over the winter despite a court challenge on the legality of the aerial practice. Pacific Wild, a B.C.-based environmental group, launched a legal petition claiming the province’s wolf cull program is unlawful because it contradicts wildlife regulations and federal aviation laws. …The wolf cull involves radio-collaring single wolves, tracking them to their packs, and then aerial gunning the animals from helicopters. The government program is supposed to help caribou populations rebound, but its efficacy is widely disputed by environmentalists and biologists. …However, on Jan. 28, the B.C. government brought in new regulations allowing the use of a helicopter during a hunting expedition. The new regulations also included other provisions where an aircraft or a helicopter can be used for or during a hunting expedition for reasons such as scientific purposes or proper management of a wildlife resource.
