Roads were built to connect us. But for wildlife, they often do the opposite.
In the U.S., more than 1 million wildlife-vehicle collisions occur each year, leading to more than 200 human deaths, roughly 30,000 injuries and over $10 billion in costs. When smaller wildlife are included, the toll grows to an estimated 1 million animals killed on roads every day. And the danger doesn’t stop at the pavement. Roads fragment habitats—disconnecting forests, rivers and wetlands. This cuts off the pathways wildlife needs to survive and leaves communities more vulnerable to flooding.
The good news? Through Northeast Habitats and Highways, a partnership with transportation agencies and other organizations across 8 states to encourage more infrastructure projects that are wildlife-friendly, that work is already underway.
Alissa Fadden, wildlife connectivity project manager for The Nature Conservancy in New York, wrote about how it's happening on the ground for Roads & Bridges Magazine.
