Wolves are vital players in various ecosystems. Sowe humans need to develop a better tolerance forthem. And the wolves need more space. That’saccording to a new study in the journal NatureCommunications.
“The key implication here is it sort of begins to reframe the entire discussion ofconservation, because historically, our model has been almost a postage stamp model, wherewe protect certain areas and try to maintain intact assemblages of animals.”
University of Washington ecologist Aaron Wirsing, who took part in the study. He says thefindings could lead to changes in how wildlife and land managers create policy.
“We need to allow predators to occupy more landscapes than just remote, protected areas, onthe other hand, we also need to heavily manage them, recognizing that they do conflict withpeople.”
That’s why Wirsing is not calling for wolves to simply roam free, throughout North America, Europe or Australia—all places the researchers examined that have dealt with conflicts amongpeople, their livestock and wolves. But wildlife management plans should take into accountthat wolves, although they do sometimes kill ranch animals, can also prevent such deaths—bydriving away other predators.
“Worldwide, smaller mesopredators like coyotes, jackals and such, actually themselves preypretty heavily on livestock and can cause a lot of economic damage.”
So wolves could become a net positive in the relationship with people. If they’re given a chance.
