SALAMON-ALBERT É., ORTMANN-AJKAI A., HORVÁTH F. & MORSCHHAUSER T. 71 variable. Between these bioclimatic indexes, BIOCLIM 12 proved to be the most effective variable for regional differentiation. Among habitat types, all of woodlands exist in a wide range of annual precipitation, K and R habitats are under a wide range, J and L habitats are under a narrow range of annual temperature as the climatic envelope. The second selected pair among bioclimatic variables is BIOCLIM 17 as the precipitation of driest quarter to BIOCLIM 9 as mean temperature of driest quarter, reflecting to quarterly climatic extremities of a short term outside the regular vegetation period (Table 2, Fig 3). The driest quarter could cause an environmental limitation in starting of vegetation period. Occurrence all of woody habitat types is characteristic in a wide range of quarterly precipitation, and a regionally differentiated narrow range of temperature. Range of climatic envelope by BIOCLIM 17 is the widest in Külső-Somogy region, the narrowest in Zselic region in all the case of woody habitats. Range of climatic envelope by BIOCLIM 9 as the mean temperature of driest quarter is also the widest in KülsőSomogy region, the narrowest is in Belső-Somogy region. Habitats are well-ordered by an increasing precipitation gradient from Külső-Somogy, through Zselic to KülsőSomogy under continuously increasing temperature variable. Between these two bioclimatic indexes, both BIOCLIM 17 and BIOCLIM 9 proved to be effective for regional differentiation, but not for the habitat types. Among habitat types, all of woodlands exist in a wide range of temperature and precipitation as well. The widest range of temperature and precipitation in driest quarter is effective as the climatic envelope in BelsőSomogy region, the narrowest range of them is in Zselic region. Range of climatic variables is in proportion to the case number of habitat occurrence.
