Roads create barriers that separate ecosystems and become a threat to wildlife. Wildlife bridges and tunnels offer animal crossings over crowded highways.
Are Wildlife Crossings Effective?
Research shows that (wildlife bridges) crossings work effectively when they are combined with fences to minimize collisions with wild animals. According to FHWA, wildlife crossing projects aim at improving both safety and connectivity.
Why Is Design Important?
Different animals require different designs. Site, fencing and conditions of the habitat affect whether animals will use the crossings.
Can Bridges Help Biodiversity?
Crossings cannot eliminate all impacts of roads but they can help to reconnect isolated habitats.
