Parks Canada says staff were forced to kill a wolf in the Pacific Rim National Park Reserve to ensure visitor safety. It says in a statement that the wolf was killed on Vancouver Island on Sunday after showing increasingly aggressive behaviour, including two attacks on leashed dogs in the Long Beach area south of Tofino. Staff had stepped up efforts to chase the animal away after posting a notice last November warning of an increase in wolf activity in the park. But Parks Canada says that failed in part because people were breaking park rules in ways that undermined the wolf’s natural wary behaviours — and staff must now try to rebuild those behaviours in the remaining members of the wolf pack
