Roads can be dangerous places for amphibians, which are often slow-moving and too small for drivers to see and avoid.
To make it safer for vulnerable populations to move freely in their natural habitats, the Nevada Department of Transportation initiated a research project to better understand amphibians’ migratory behaviors and the effectiveness of road and fence design options for funneling the animals to designated passageways.
