20 Natura Somogyiensis Distribution of natural and semi-natural areas I wetlands grasslands I I forests Fig. 3: Distribution of natural and semi-natural areas Regarding cover data too, most of natural and semi-natural areas are mesophilous forest (K group, 8000 ha), more precisely oak-hornbeam forests (K2). More than half of these forests are in Baranyai-hegyhát. Area of well-lighted dry oak forest is about 3000 ha, most of them are turkey oak — sessile oak forests (2300 ha) and closed mixed steppe oak woodlands on foothills (L2x, 700 ha); 70% of them are in Tolnai-hegyhát. Next habitat types with significant area are uncharacteristic grasslands (OB, OC - 2000 ha) and bushes (P2a, P2b - 2300 ha) showing that degradation of grassy habitats by overgrowing with scrubs, due to abandonment of grazing, is similar to countrywide negative trends. Other habitat types with with an area worth mentioning are dry and semi-dry closed grasslands (1600 ha) and reedbeds and sedge habitats (near 1000 ha) (Fig. 5.) Detailed description of habitats Wetland habitats Wetland habitats (A, В groups) cover less than 1% of total area, 5% of natural and semi-natural vegetation. Euhydrophyte habitats (A group) are especially poor, represented only by A1 type (standing water communities), due to the fact that natural lakes are missing here, and intensive fishponds and canals are not appropiate for them. Marshes (B group) are more widespread (625 ha) and diverse (6 of 7 MÉTA types), but most of them are narrow, fragmented reed or Typha stands at the edges of canals and
