Relative importance of woody habitat types represent more than the half of the total number of habitats listed for Hungary in this region. Semi-natural woodlands have the relative greatest area, among them riverine swamp and mesic woodlands are dominating (J+K+P habitat types) in the central and western part of the region. Dry woody habitat types are in subordinated position in the central-northern and south-eastern parts (L habitat types), shrubs are concomitants or substituents of semi-natural habitat patches (P habitat types). In landscape elements which are poor in woodlands uncharacteristic woody habitats and dry woodland fringes (R and M habitat types) are significant. Regional land and forest management ought to have preserve actual condition of woodlands in Külső-Somogy. Keywords: GIS database, MÉTA method, habitat patches, woodlands, landscape ecology Introduction Külső-Somogy is a characteristic hilly landscape in the middle of Transdanubia belonging to Kaposense and Somogyicum phytogeographical regions of Hungary. This landscape is the least revealed and documented area in Transdanubia according to its flora and vegetation. Published botanical data of species of (semi-)natural vegetation stands are sporadic (HORVÁT 1943, KEVEY and HORVÁT 1986, KEVEY 1988, 1989, 1993, 1995, 2001). Reference points for the southern and western zones of Külső-Somogy region are basic or correspondent vegetation descriptions and analyses of the sorrounding areas (e.g. Zselic, Belső-Somogy e.g. Borhidi 1984, Juhász 2005). Results of complex botanical mapping and research started in the last decade (BARTHA et al 2002) would be presented as reference verifying and finding new occurrences of plant species (e.g. KIRÁLY 2007) or as corresponding analyses of semi-natural vegetation. In our work, as a first study of a landscape series, we present and evaluate characteristic woody habitat types and groups, their patches with areal data and spatial patterns in Külső-Somogy region at landscape scale. Analyses are implemented with MÉTA method and mapping
