With its distinctive markings and a mating call that can be heard up to 2km away, the natterjack toad is one of Britain’s most striking amphibians. It is also one of the rarest, with less than 50 breeding populations in mainland Britain. Britain’s prolonged dry weather threatens to make it rarer still and Natural England is stepping in to take early action to help the natterjack make it through the drought: here.
