Natura Somogyiensis

gons habitat types, roughly estimated areas and vegetation attributes are listed (e.g. naturalness, neighbourhood, land use). This database is suitable to determine naturalbased habitat quality and to compose the prognosis of future changes for vegetation and landscape (Salamon-Albert and Horváth 2008a,b). Our study area consists of 31 whole META quadrants and of 23 quadrant-parts.

Analyses and maps are based on vegetation type and area data of META database. Occurrences and area data of each habitat type were summarized for quadrants, and some types were contracted (see detailed analyses). Data query was performed with MS SQL, GIS analysis were executed and maps prepared with ArcGIS 3.1 (Horváth and Polgár 2008).

Habitat groups occurring in the study area are as follows, bold ones are representing habitats covering larger areas. Habitat nomenclature and codes are by Bölöni et al. (2003, 2007).
