Wolves are vital players in various ecosystems, so we humans need to develop a better tolerance for them.

And the wolves, they need more space. That's according to a new study in the journal Nature Communications.

The key implication here is that it sort of begins to reframe the entire discussion of conservation,

because historically our model has been sort of almost a postage stamp model where we protect

certain areas and try to maintain intact assemblages of animals.

University of Washington ecologist Aaron Wersing, who took part in the

study, says the findings could lead to changes and how wildlife and land managers create policy.

We need to allow predators to occupy more landscapes than just remote protected areas. On the other hand,

we also need to heavily manage them, recognizing again that they do conflict with people.

That's why Worsing's not calling for wolves to simply roam free throughout North America, Europe or Australia.

All places the researchers examined that have dealt with conflicts among people, their livestock, and wolves.

But wildlife management plans should take into account that

wolves, although they do sometimes kill ranch animals, can also prevent such debts by driving

away other predators. Worldwide, smaller meso predators like coyotes, jackals and such, actually

themselves prey pretty heavily on livestock and can cause a lot of

economic damage. So wolves could be coming out positive in their relationship with people if they're
