Results

Overwiew of natural and semi-natural habitats

Natural and semi-natural habitats (all META types except RD - Uncharacteristic woodlands and plantations mixed with non-native tree species) are preserved best in Baranyai-hegyhát (34% of total area), in Völgység and Tolnai-hegyhát far less (11.7% and 12%, accordingly). Much of natural and semi-natural vegetation in Baranyaihegyhát and (74%, 58%) or almost half of it (Tolnai-hegyhát: 46%) is made up of forests, located in three blocks: in the whole area of Baranyai-hegyhát (adjoining to forests of Mecsek hills), and two isolated remnants of woodlands on hills SE from Kapos valley: one of them is on the border between Völgység and Tolnai-hegyhát, the other one is on the northern part of Tolnai-hegyhát. On deforested areas near-natural vegetation consists of small patches of grasslands and wetland habitats mostly along streams, and uncharacteristic tree stands (Fig. 3.)

45 habitat types occur in study area, 53% of all Hungarian vegetation types. Most of types can be found in Tolnai-hegyhát (38 types, 45%), some less in Baranyai-hegyhát and Völgység (34 types, 40%, 32 types, 38%). Woody habitat types are most diverse in Baranyai-hegyhát (12 types, 48% of woody types), which has less continental climate and lies closest to forest-covered Mecsek hills. Regarding only mesophilous forest (K group), their representation is 80%, only acidophilous beech forests are missing. Grassland habitat types are most diverse in Tolnai-hegyhát, close to the forest-steppe zone (25 types, 45% of all grassland types). Woody habitat types are also more numerous (10/40%) here than in Völgység, laying closer to woodland-rich Baranyai-hegyhát, because of dry forest types (L group). Grassland habitats are far less diverse in Baranyaihegyhát and Völgység (18 types, 32%) (Fig. 4).
