When frogs and salamanders wake from winter hibernation in woodlands, they head toward breeding ponds - a treacherous journey if a route intersects with a road. Grassroots crossing initiatives have spread across the US in the last two decades, with volunteers shepherding tens of thousands of amphibians and collecting data that has led communities to build tunnels and close roads to cars on busy migration nights. In New Hampshire, Harris Center for Conservation Education salamander crossing brigades have been collecting data since 2007 that has prevented development approvals. In Waterloo, New Jersey, volunteers helped between 1,000 and 2,500 amphibians across a particular street for years, helping to make the case for building a passage under the road.
