Reducing Roadkill By Design

My previous blog post on Nature’s wildlife corridors proved to be a very popular subject. So, I have decided to share a recent article with you that provides a great example of what can be done to create new wildlife corridors when people work together to create connections between wildlife ecosystems.

Orion Magazine published this article by Andrew D. Blechan entitled Right of Way  which I provide here in its entirety. Orion provides an informative video that accompanies this piece.

 

 

WHEN THE MONTANA Department of Transportation approached the Confederated Salish and Kootenai Tribes about widening the portion of U.S. Highway 93 that bisects the Flathead Indian Reservation, the tribes resisted. They first wanted assurances that any highway expansion would address the spirit that defines this region of prime wildlife habitat and natural wonders. The primary goal for the tribes was to mitigate the impact of the road on wildlife.

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.

Collaboration between the tribes and highway engineers, with help from Montana State University and Defenders of Wildlife, led to the creation of the most progressive and extensive wildlife-oriented road design program in the country. The 56-mile segment of Highway 93 now contains 41 fish and wildlife underpasses and overpasses, as well as other protective measures to avoid fatalities. As creatures become accustomed to the crossings, usage is increasing — at last count, the number was in the tens of thousands. Motion cameras have captured does teaching their young to run back and forth through the crossings, much like human mothers teach their children to safely cross a street.

Wildlife crossing structures are such a smart idea that it’s difficult to understand why they’re still a rarity in this country. But by insisting on rebuilding highway infrastructure to address the needs of wildlife, the Salish and Kootenai tribes have led the way toward a greater sensitivity to fragmented habitats. Highway departments around the country are now studying their example.

  1. Working on this topic in two weeks! Can’t wait to include this. Thank you so much!

    • I am delighted to help a fellow educator Deb. Hope tings are going well for you

      • Used this today! YEAH! I set the activity up by first playing a game called Island Hopping to teach about Island Biogeography, Habitat Fragmentation and Edge Effect. Then we did a socratic seminar on an activity called “Do Corridors Have Value in Conservation?” by Andrea Bixter, Department of Biology, Clarke University, Dubuque, IA. We followed up with your blog and the video. This series worked really well and I am happy to share all of it with any educator interested.

        • Hi Deb: What you have done is very important. I have many educators who are part of my 6,000 Twitter followers.I can set up a Tweet either to central repository for all the information or I can be the junction point if you wish. I can also put your material reference URL into my new section on lesson plans.Let me know what you want me to do.
