FastCoExist published a piece on a new approach to highway design that takes wildlife into account.
While people view highways as a means of getting from one place to another, to wildlife they are just the opposite: a barrier. Highways turn contiguous habitat into haphazardly fragmented islands where animals must either find their way across, or learn to feed, roam, and reproduce in an increasingly limited area. Four grizzlies were killed in traffic collisions between 1998 and 2010 on the Flathead reservation section of highway. Thousands of deer and western painted turtles also perished, along with countless other animals, including mountain lions, wolves, and moose.
