| Description | The aim of this paper is to describe occurrence of broad-leaved semi-dry grasslands of the Bromion alliance, distributed on a patch of crystalline dolomitic limestone north of village Nová Ves (district of Třebíč, south-western Moravia, Czech Republic). In the study area, vegetation of the Bromion alliance reaches the upper altitudinal limits of its distribution and is supported mainly by the specific geological substrate and the direct connection of the area with the Jihlava river valley (in the past, this connection may have played an important role in plant migration). Broad-leaved grassland vegetation of this area was classified into the association Carlino acaulis-Brometum erecti Oberdorfer 1957, within the Bromion alliance. Species composition of this vegetation is in a sharp contrast with composition of acidophilous grasslands occupying similar habitats in surrounding areas of acidic metamorphic substrate, which are represented mainly by the associations of Sedo-Scleranthetea class and Koelerio-Phleion alliance. Notes on phytogeographically interesting species are included. |
