This book takes the reader on a journey through two counties, Győr-Moson-Sopron and Vas. Travelling through these landscapes gives you a true cross-section of Hungary's natural history, with a wide variety of habitats from salt marshes to floodplains and mountain forests. A special, unique feature is that the western edge of the region is already under alpine influence, which is reflected in the more precipitous climate and the composition of the fauna. It is also home to plant and animal species that are rare or absent in other parts of the country. In Western Transdanubia, two national parks and five landscape protection areas form the larger units of protected areas. These are briefly described at the beginning of the book. Typical species are grouped according to their habitat. For reasons of space, it has obviously not been possible to include all the beautiful, interesting and important species of flora and fauna of this rich and varied landscape. I hope, however, that this is enough to convince the reader of the beauty of the Western Transdanubian region, its richness in natural values, and to reinforce the will to preserve these values.
