92 NATURA SOMOGYIENSIS mental conditions of the moor and the surrounding forest, the lake-, moor-and terrestrial species get either a habitat or a swampy area. The number of species is large, whereas the number of individuals is small. The study gives a detailed account of the changes incurred in the bird population during the past four decades, and it also deals with the seasonal movement of the bird reign. Only the Misgurnus fossilis can be indigenous from fish in the moor of the Baláta. In the course of time the other nine found fish species were introduced to the open waters of the area. Ten species live in this area out of amphibians. It means two-thirds of the domestic species. Characteristic species: Titurus vulgaris, Bombina bombina, Rana arvalis Wolterstorffi. These are eurytop animals of flat-and hill-country. There are nine reptile species and five varieties in this area, which is more than 50% of the Hungarian species. They are all eurytop species of flat-and hill-country except for the two viper species, which are stenotop species. The Vipera berus var. prester belongs to the fauna peculiarities of our country, which is known for only one other locality within Hungary Characteristic species: Emys orbicularis, Lacerta viridis viridis, Natrix natrix, Vipera berus berus. We observed the presence of 36 mammal species. Thus about half of the 81 domestic mammal species live here. The shrews (Soricidae) and the mice (Muridae) have the largest number of individuals. It is the speciality of the mammal fauna in the Baláta, that four big game species (wild-hog, red deer, fallow deer, roe-deer) live in great strength in this reserve, which is part of the big game reserve of the wider surrounding. The final part of the study deals with the possible future of the native moor by outlining the tasks of nature conservation, forestry and economy of watersupplies. The scientific research of Baláta is not completed. Numerous groups of invertebrate animals are not explored. Further faunistic and ecofaunistic examination of the vertebrate animals is also desirable.
