ravon (Reptile, Amphibian & Fish Conservation the Netherlands) started in 1999 with the compiling of all records of amphibians and reptiles in the Netherlands. Different databases were brought together and enormous amounts of ‘paper records’ were digitized. These data, combined with ecological knowledge from scientific publications and the experience of many professional and voluntary specialists, are brought together in this book. This book is an account of the present knowledge of the morphology, ecology, behaviour, diversity, threats and conservation of Dutch amphibians and reptiles, including extensive accounts on sea turtle observations and some introduced species. Chapters on cultural history and the history of herpetology in the Netherlands are also included. This book presents the distribution of amphibians and reptiles in the Netherlands up to 2007. A summary of the various chapters is given below. Summaries on distribution, status and some special remarks are given at the end of each species account.
