“Toad Tunnels” Built to Help Amphibians Cross Roads

Later this month, when the next warm, wet rain soaks the northeastern U.S., it will signal thousands of American toads to hop to their breeding ponds. To get there, many of the toads will cross roads that slice through their habitat.

John Serrao, a naturalist in Pennsylvania’s Pocono Mountains, says that unless Buffo americanus and other amphibians get help crossing the road, their local populations will disappear.
