Wildlife Bridges and Crossings

This week on The Backyard Naturalists, Debbie Foster and Laurie Horne explore the fascinating world of wildlife bridges, wildlife crossings, green bridges, and ecoducts — structures designed to help animals safely move across fragmented habitats caused by highways, railroads, canals, and other human-made barriers. From deer, elk, badgers, mountain lions, alligators, amphibians, turtles, and even endangered red wolves, these crossings are becoming an increasingly important tool for protecting wildlife and people alike. Debbie and Laurie discuss how wildlife crossings have been used in Europe since the 1950s, why places like the Netherlands and Banff National Park in Canada have become models for large-scale wildlife passage, and how thoughtful design — including native plants, fencing, underpasses, overpasses, and species-specific construction — can dramatically reduce wildlife-vehicle collisions. The episode also highlights current and future projects in North Carolina, including work along I-40 in the Pigeon River Gorge and US 64 near Alligator River, where crossings may benefit black bears, bobcats, turtles, snakes, and the critically endangered red wolf. Whether you're a longtime nature lover or just learning about the hidden ways wildlife moves through our landscapes, this episode offers a hopeful look at how smart planning and conservation can make roads safer for everyone — humans and animals included.
