Abstract
|
This is a review of fifty-one non-native species, subspecies, intergrades or hybrids of amphibians and reptiles recorded as living wild in the London Area. Of these fifty-one taxa, referred to here as ‘types’, around twenty-one are amphibians of which fourteen have bred successfully and thirty are reptiles of which just two have been proven to breed. Other types may have bred unrecorded. A rapid increase in the number of types of terrapin in the wild has been observed since trade restrictions on red-eared terrapin importation in 1997. Many new species, mostly North American, but including those from Africa and Australia, can now be found in the wild. The traditional split of Water Frogs into two species and a hybrid has now diversified to include many more types that may interbreed when mixed. The distribution and spread of Water Frogs over the last two hundred years in this part of southeast England is described for the first time. Brief descriptions and identification notes are provided and zoogeographic and historical aspects of colonization are considered. Part 1 refers to distribution and aspects of impacts from the species’ role in the food chain of the communities where they have colonized. The trade in herpetofauna and nature conservation and welfare issues are considered. Aspects of disease impacts and philosophical considerations are described in Part 2.
