Natterjack Toads on Springwatch (2017)

Martin heads to the North Wales coast to see how John Buckley and the Amphibian and Reptiles Conservation Trust has helped to save the Natterjack Toad there.

The Dutch Wadden Sea Society reports that the natterjack toads of Terschelling island have woken up from their hibernation.

In the Koegelwieck nature reserve, in central Terschelling, each night there is a massive concert by male natterjack toads. This is audible even on the beach and in Den Hoorn village, kilometres away.

Another good natterjack spot on Terschelling is the Groene strand beach in the west of the island.

In the Netherlands as a whole, natterjack toads are threatened. Not so on Terschelling: the related species, the European toad, common in the continental Netherlands, does not occur there.
