Abstract:Vehicle collisions with animals threaten the lives and safety of wildlife and motorists. In an attempt to reduce vehicle collisions with animals, additional infrastructure was installed under bridges and within culverts to allow wildlife to pass beneath sections of highway. Photo evidence suggests that wildlife will usually use these structures, and a reduction to roadkill near these passages suggests that wildlife may prefer these safer routes as opposed to passing through traffic. These results should encourage the further study and development of wildlife crossing for the protection of motorists and environmental integrity.
