Did you know? tunnels for toads

Each spring, toads and other amphibians return to the pond where they were born.
However, they often have to cross roads on their journey, which is a risky business!

The Plain of Sorques, in Montigny-sur-Loing, is home to numerous toad, frog and newt species. In order to allow them to cross the road that separates the forest from the ponds and river they make their way to each year to reproduce, special tunnels have been built.. The ingenuous system designed uses wooden barriers that channel the animals into small tunnels made for them under the road. Thanks to these tunnels, thousands of amphibian friends have been able to stay alive during their reproductive period and raise the next generation.
