Abstract: A survey of the distribution of amphibians was carried out in Sunderland (Tyne and Wear). Five species were present in the area, but Triturus cristatus and T helveticus were uncommon. All the amphibian species were declining or apparently extinct in wild ponds. Garden pools were less common than in other parts of England that have already been surveyed, and as a result of the low density of ponds many had not been colonised by amphibians. There was an encouraging number of colonies that had been started by deliberate introduction however. Rana temporaria and T vulgaris were the only species that had colonised the ponds to any great extent . Both were found to be very susceptable to fish predation, and mechanisms for surviving in fish ponds are discussed. A n other danger was the destruction of garden ponds which was astonishingly common.
