Abstract

A new closed rock sward association ( Festuco rupicolae-Arrhenatheretum Erdős et Morschhauser, ass. nova.) has been found and described in the Villány Mts (SW Hungary). This community lives in northern expositions, near the ridge or the plateau. Bedrock is limestone and dolomite. In the association dominated by the grasses Festuca rupicola and Arrhenatherum elatius , an unusual mixing of species can be encountered: species of the mesophilous forests, of the karst shrub-forests and of the xerophilous grasslands and rock swards occur together in this community. Description of the new community as a distinct association is supported by the PCoA ordination and the differential species. Ecological properties of the community were characterised by using ecological indicator values. This analysis also shows the dual character of the association. We analysed the new association by computing the spectra of the social behaviour types. The extraordinarily great amount of the disturbance tolerants is probably a consequence of the former grazing pressure or some other disturbance.
