Okay so maybe the wolves aren’t literally helping deers to cross roads in Wisconsin, but they are helping to keep them away from the motorways and (by extension) preventing them from becoming another roadkill statistic.

With the return of wolves to Wisconsin, their prey species have had to change their behaviour to minimise the risk of becoming the next item on the menu. One of these changes has been to avoid roadways and other human structures, since these cleared areas make ideal wolf hunting grounds. They do of course also catch the odd deer, but it is the added ability to scare the deer away from roadways which makes wolves a more efficient prevention technique for deer collisions than the traditional approach of keeping deer population down through hunting.

Wolves are a polarising topic – with divided opinions as to if they should be re-introduced to the wild or not. This landscape of fear that the wolves create is clearly a tick in the win column for having wolves around. As twitter user @edyong209 points out; the wolves could actually be helping us solve a human engineered problem by keeping the deers at bay.
