Adrian Treves Professor, Carnivore Coexistence Lab, Nelson Institute for Environmental Studies, UW–Madison "Wolf policy and its effects on illegal killing, human tolerance, and recovery" Reporting new evidence from Wisconsin’s wolves, red wolves and Mexican gray wolves, Dr. Treves presents the state of the science on endangered wolf policy. Four lines of evidence show that ‘blood does not buy goodwill’. Legalizing wolf-killing does not raise tolerance for wolves, does not reduce poaching, and slows population growth more than expected from legal mortality. The best available science shows that cryptic poaching and concealment of evidence increases instead. Therefore, lethal management of predators should be reformed.
