. Floristic data on the occurrence of Hepaticae at 939 localities of 10 2 ‐ 10 3 m diameter in the Nizky; Jesenik Mts. (area 3624 km 2 ) were subjected to TWIN‐SPAN classification. The results were interpreted in terms of the site conditions at each locality. Groups of localities showed marked differences in distribution within the areas, mainly in relation to altitude and substrate. The grouping of species partly corresponded to their sociological behaviour (i. e. their distribution on a smaller spatial scale). Joint occurrences of species of different sociological groups indicate the presence of habitat complexes whichbecome apparent on the larger spatial scale. The use of such data in landscape ecology is discussed.
