Join Rene Wendell, resident naturalist at The Trustees of Reservations‘ Bartholomew’s Cobble in Sheffield, MA, as he takes a group of volunteers into a misty March (2011) night to help migrating amphibians cross a busy road. We encounter: spotted salamanders, spring peepers, wood frogs, four toe salamanders, red backed salamanders, and an American toad.
Translated from the Dutch RAVON herpetologists:
The Netherlands helps over sixteen kilometers of amphibians to cross roads

A traffic jam from Almere to Amsterdam; so long would the procession of toads, frogs and salamanders be, if all animals helped by volunteers to cross roads in the spring of 2014 would be put behind one another. The toad working groups during the months of March and April are estimated to have helped a total of more than 230,000 amphibians across the roads. These are about 50,000 more than last year but still not as many as in the boom years 2008, 2010 and 2011, when more than 300,000 amphibians were transferred.
The complete spring 2014 report is here.
