Advocates Call for More "Climate-Informed" Wildlife Crossings

Advocates in North Carolina and nationally are calling on decision makers to expand the use of climate-informed wildlife crossings.

Given the vast number of miles of roadways in the U.S., the nation has relatively few wildlife crossings compared to Europe and Canada. This week advocates released a joint statement calling on Congress and state lawmakers to expand the use of climate-informed wildlife crossings to create safer conditions for animals and motorists.

Federal government research estimated there are 1-2 million collisions between vehicles and large animals in the U.S. each year.

Ron Sutherland, chief scientist for the Wildlands Network and a resident of Durham, said well-designed crossings can improve safety for animals and humans.

"Directional fencing that you put along the highway, if you do it in the right way, you can actually steer the animals to the crossing structures, and the combination of fencing and structures either overpasses or underpasses," Sutherland explained. "That's what leads to reducing the level of wildlife vehicle collisions by as much as 90%."

The 2021 Infrastructure bill set aside $350 million for a wildlife crossings pilot program, but advocates are calling on Congress to create permanent federal funding, incorporating the costs of planning and construction, along with ongoing maintenance and monitoring needs.

In studying different designs, and which species prefer what kinds of crossings, Sutherland pointed out researchers are able to site underpasses or overpasses based on which species need accommodation at particular locations.

Advocates are calling for climate-informed designs to not only support animal migration in response to climate change, but to help roads survive extreme weather events.

"The design of these crossing structures can actually increase the ability of the road to survive climate disaster events, like major floods, by creating these large gaps under the highway," Sutherland noted. "Along streams and rivers, you provide room for animals to go underneath, but when there's a major flood, because we get 12 inches of rain, then the road doesn't wash out."

Advocates said the current federal pilot is a small fraction of what's ultimately needed. Sutherland emphasized in North Carolina alone, researchers identified the top 20 places to locate wildlife crossings, but another 159 locations are also seen as highly needed.

When the conversation turns to cost, Sutherland takes a longer view.

"From a safety standpoint, the crossing structures pay for themselves easily over time, if you put them in the right places," Sutherland contended. "In terms of reduced collisions with these large bodied animals, they can cost tens of thousands of dollars for one of these crashes, and so it doesn't take that many of them to pay for a crossing."
