Abstract

In our study climatic sensitivity of significant woody habitats are discussed in the territory of vegetation based landscape regions of South Transdanubia, including Belső-Somogy, Külső-Somogy and Zselic. Selected bioclimatic variables are used to characterize regional and habitat climate surfaces and envelopes by habitat occurrence. Gaussian probability curves were fitted, using long term (1961-1990) data for yearly and quarterly temperature and precipitation variables, representing general and extreme climatic conditions. Studied woodlands are sufficiently integrated into the climate surface and envelopes of the region, according to multipeaks of bioclimatic indices. Among woody habitat types, riverine and swamp woodlands (J) turned to be the most climate sensitive habitats, due to their few peaks with extreme values by numerous bioclimatic indices, especially yearly and quarterly precipitation variables. Mesic deciduous woodlands (K) are no directly climate sensitive on temperature relations, but they are like on the short time quarterly precipitation. Peaks of dry closed deciduous woodlands (L) and other tree dominated habitats (R) are completely fitted to regional climate surfaces and envelopes, so they have no significant climate sensitivity by any analysed bioclimatic variable.
