This thesis summarises historical and recent information on the distribution of butterflies in South Bohemian region, based on 130 records from literature, collections and recording reports, amassed during Mapping of Czech Republic butterflies. Historical and present distributions of each of 130 butterfly species found in their region are displayed on distribution maps. Out of the 130 species, 42,1 % is already extinct, while 24,1 % is threatened to some extend. Comparison with the situation in entire Czech Republic reveals a higher rate of extinctions, which is probably a function of smaller total area. Compared with the Czech Republic total, xerophilous species suffered higher losses in South Bohemia, whereas species of mesic habitats are relatively less endangered and for peat bogs specialists, the region represents a major refugium. Priorities for further research and active conservation measures are discussed. |
