This is a piece of old news, but good news, and it reminds us that in the effort to protect people and wildlife on our urbanizing landscape, people can use a variety of tools. Fencing is a cost-effective tool that can go a long way towards protecting wildlife and people from each other when it’s placed appropriately. In this case, fencing was installed along the 241 freeway in Orange County from the 261 to 91 freeways – an important wildlife corridor for cougars, and one that represented an area with high mortality. Since the fence was installed in 2014, there have been no vehicle-wildlife collisions within the project area. The SR-241 Wildlife Protection Fence Project was honored with the Innovative Transportation Solutions award in 2015 by the Orange County chapter of the WTS, an international organization advancing women in transportation planning.
