SALAMON-ALBERT É., ORTMANN-AJKAI A., HORVÁTH F. & MORSCHHAUSER T. 73 Discussion There were differences among climatic surfaces of the regions by all the bioclimatic variables. Vegetation-based landscape regions along a rough east-west gradient were ordered by bioclimatic indices originated from precipitation data in each habitat, similarly to other South Transdanuian small regions (ORTMANN-AJKAI and HORVÁTH 2009). This trend was not revealed by bioclimatic indices calculated by temperature data. In spite of differences in climatic variance, woodland habitats occurred under similar bioclimatic conditions. Riverine and swamp woodlands (J habitats) have high water demand, so they occur mostly in the wetter part of the climatic envelope. Their occurrences in climatically drier areas - especially in Külső-Somogy - shows that they are edafic communities. Mesic woodlands (K habitats) in drier Külső-Somogy are more constrained to areas of lower temperature index, showing their marginal phytogeographical position. Contrasting to that dry woodlands (L habitats) occur dominantly in Külső-Somogy, in the whole temperature range, showing that this region is close to their phytogeographical optimum. Secondary forests (R habitats) cover climatic envelope of both mesic and dry forests, because they were planted to the place of both of them (see Fig.4). Variable case number of any woody habitat types in the regions cannot be explained by climatic conditions only, it could be interpreted by land use and management data also.
