The data set consisting of 41 phytosociological relev¨¦s was obtained by the authors in two vegetation seasons in 2008 and 2009. The numerical classification and the ordination methods were applied to determine the main vegetation types and to explain the structure of the vegetation-environmental data matrix, respectively. Four associations within two classes were distinguished: Luzulo albidae-Quercetum petraeae Hilitzer 1932, typical for shallow, mineral-poor and acidic soils, Melico uniflorae-Quercetum petraeae Gergely 1962 occuring on mesic stands with skeletal and deeper soils, Poo nemoralis-Quercetum dalechampii om ¨¢k et H¨¢berov¨¢ 1979 developing on moderately canopyopened stands in the submontane belt, Sorbo torminalis-Quercetum Svoboda ex Bla kov¨¢ 1962 growing on moderately acidic substrates in drier regions. The major environmental gradients responsible for variation in forest species composition was associated with soil nutrient and soil reaction following the Ellenberg indicator values as well as the measured environmental variables (C/N-ratio and soil acidity). Special attention was given to the discussion on species composition and site ecology. %K classification %K phytosociology %K ecology %K Quercetea robori-petraeae %K Querco-Fagetea %K gradient analysis %K the Western Carpathians %U http://versita.metapress.com/content/945556510w240671/?p=e9dc94f6894e4e3495b74c461d230c85&pi=4
