400 Miles to Cross: The Interstate 80 Wildlife Barrier

THIS IS WHY SOME DEER MIGRATE 150 MILES — BUT NO FURTHER. THE SOLUTION WILL MAKE YOU HOPEFUL.

This new film shows how Interstate 80 in Wyoming is an almost impenetrable obstacle to movement of pronghorn, elk, and deer, including animals in the herd of world-record migrator Deer 255. The highway has severed or truncated migration corridors originating as much as 150 miles away, and it interferes with movement of tens of thousands of animals. Over time, barriers to seasonal habitats can decrease the abundance of the herds — populations that are important to Wyoming’s hunting and tourism industries. The good news is that Wyoming and other Western states have the science and the tools necessary to fix this problem.
