#38: Beth Pratt – The Age of Wildlife Crossings

#38: Beth Pratt – P-22 And The Age of Wildlife Crossings Nature's Archive

Summary

Highways, roadways, and railways isolate animals, prevent them from reaching needed food and water, cause genetic isolation, and make populations vulnerable to natural disasters. And as you’ll hear today, the impacts go much deeper, and sometimes in surprising directions. 

But wildlife crossings go a long way towards mitigating this damage.

Today, my guest Beth Pratt of the National Wildlife Federation and Save LA Cougars tells the astonishing story of how a Los Angeles mountain lion named P-22 triggered a cascade of support leading to one of the most ambitious wildlife crossings ever conceived. This crossing, called the Wallis Annenberg Wildlife Crossing at Liberty Canyon, is about to break ground over the 10 lane US-101 highway.

Beth tells us about how P-22, with support from amazing people like Beth, helped the second largest city in the United States wake up to the fact that we need to find a way to coexist with nature. And we also discuss some of the nuts and bolts of wildlife crossing design. For example, she discusses the pros and cons of overpass crossings vs tunnels and culverts, and how design can be used to influence animals to use the crossings. And of course, the specific wildlife protection goals influence the design, too.

Beth also describes many surprising ways that wildlife crossings help improve ecosystems and the food web. Even plants need connectivity, and some bird species are negatively impacted by highways – and these crossings aim to help.

A bit more about Beth Pratt. Beth has over 25 years experience in environmental leadership, and is currently the Executive Director of the California Region for the National Wildlife Federation. Beth previously served as Vice President and CFO at the Yosemite Conservancy, and also serves on the board of Outdoor Afro.

If that wasn’t enough, Beth authored the book “When Mountain Lions are Neighbors”, which was highly influential in my progression as a nature advocate. Beth and her work have frequently been featured in the media, including a recent piece in the LA Times by Louis Sahagún (who coined the term “The Age of Wildlife Crossings” in this article).

You can find Beth online at bethpratt.com, on Twitter @bethpratt, and on Facebook @bethpratt1. And of course, you can also find P-22, the talented mountain lion that he is, on Twitter @p22ofhollywood and Facebook @p22mountainlionofhollywood.

  1. I first came across these crossings years ago when I lived in Europe. I think they are a wonderful idea and would hopefully cut down on wildlife being hit and killed here in the states. We keep building communities and displacing all the wildlife in that area so where they supposed to go and how do they get there. But we need them all over…So hopefully they start becoming more of a reality.

    1. Totally agree! And as Beth mentioned in this episode, it is much worse than just the road kill. Isolated populations lead to genetic decline. California just passed legislation that requires wildlife crossings to be considered for all new roads and road improvements. “A.B. 2344 would require Caltrans to identify barriers to wildlife movement and prioritize crossings when designing new roads or making road improvements.” https://leginfo.legislature.ca.gov/faces/billTextClient.xhtml?bill_id=202120220AB2344
