New research from Dr. Adrian Treves and his colleagues Drs. Francisco Santiago-Avila and Ari Cornman highlights that lethal management of wolves to prevent depredation of livestock on properties in Michigan may be ineffective and could create detrimental effects for neighbouring properties.

The paper, titled Killing wolves to prevent predation on livestock may protect one farm but harm neighbors, was published by Public Library of Science, or PLOS One earlier this month. The researchers were given access to 16 years of data on wolf depredation and control in Upper Michigan and used multiple methods to analyze it. What they found was, in their words, that “given the evidence available, we cannot conclude that lethal management had the desired effect of preventing future livestock losses.

There is also evidence of a spill-over effect to other properties in the region.

The questions raised by this study play into a paper published by Dr. Treves with several colleagues in Nature Ecology and Evolution, titled Intergenerational equity can help to prevent climate change and extinction. This is an important subject that combines ethics, environmental sciences, and how we as a society, and as a species, must look at what we’re doing today and how it will impact tomorrow’s world.

Dr. Adrian Treves of the Carnivore Coexistence Lab at the University of Wisconsin-Madison joined Defender Radio to explore the implications of his latest wolf depredation study, the importance of adapting policies to match science, and how we can all play a role in safeguarding wildlife and the environment for future generations.
