This week the city of Wageningen has introduced two tunnels under a busy road that allows ringed snakes and salamanders to cross safely. These passageways have been around for toads, but are new for snakes and salamanders.
The 50 cm (20 in) wide tubes have been set up so that the amphibians are automatically guided through the safe passageways. In the spring snakes and salamanders come from the higher elevated (hard to imagine in this flat country ;-)) Wageningse Berg, where they hibernate, down to the flat meadows, where the snakes look for a breeding place and salamanders for water. Nine other new ‘eco-passages’ are planned for the Gelderse Vallei area.
