62 NATURA SOMOGYIENSIS Fig. 5: Spatial patterns of precipitation variables as the regional climate surface a) BIOCLIM-12 the annual precipitation, b) BIOCLIM-17 the precipitation of driest quarter, c) BIOCLIM-18 the precipitation of warmest quarter, d) BIOCLIM-19 the precipitation of coldest quarter. More sign and abbreviation see in Material and methods hills in both other small regions; presumably they must be more abundant before anthropogenic landscape management. Riverine oak-elm-ash woodlands (J6) is rare, already extirpated from widening valleys fit for cultivation. Mesic deciduous woodlands (K habitats by Fig 6c) are widespread in all three vegetation based landscape regions, that are clearly distinguished by their subtypes. Lowland pedunculate oak-hornbeam woodlands (Kla), with dominance of Quercus robur, demanding more temperate conditions, and it is most abundant in Belső-Somogy. Zselic is the real home of sessile oak-hornbeam woodlands (K2) and beech forests (K5). KülsőSomogy has a very fragmented forest cover (

SALAMON-ALBERT et al. 2010a), but all three types of mesophilous forests occur here, implying a diversely forested landscape before human extension. Closed dry deciduous woodlands (L habitats by Fig 6d) exist here on the edge of their climatic zone (BORHIDI 1961, OZENDA and BOREL 2000), all their types occur in KiilsőSomogy. The zonal turkey oak-sessile oak woodlands (L2a) are the most widespread, the more continental closed thermophilous oak woodlands (LI) occur in the most continental northeastern part, corresponding to high values of seasonality and low values of
