Bauer, Norbert: Open sandy grasslands of the Bakony region
ruderal grasslands develop, and after significant effects (because of their typical weak seed pool) they are unable to regenerate. Except for the patches in the region of "Fenyőfői Osfenyves" and the "Szentbékkállai Kőtenger", the above presented sandy grasslands of the Bakony region are not given significant attention from a natural protection point of view. As opposed to the relative species weakness and because of their weak regenerating potential, especially the calciphobe sandy grasslands (mainly those at Nagytevel, Hegyesd) should be paid more attention to. In addition, the border regions of the protected areas also has to be extended near Feny őfő-Bakonyszentlászló in order to preserve this phytogeographically important place with all its protected species. CONCLUSIONS Several associations of the open sandy grasslands are recognized from the sand-beds of the margins of the Bakony Region. In the environs of Fenyőfő and Bakonyszentlászló the dominant association of the open sandy grasslands on the sandy surfaces with changing calcic-amount (it comprehends both calcareous and acidic patches) is Festucetum. vaginatae. Here, more recently, a few stands of the Festuco vaginatae-Corynephoretum association have also been recognised. These suffer from a number of disturbing effects. The Festuco vaginatae-Corynephoretum association exists in the glades of Festuco vaginatae-Pinetum sylvestris, at forest edges, and in the margin of recultivated bauxite-mine on pioneer sandy surfaces. Earlier this could have been more frequent in areas of the so called forest-grazing, which was a typical form of local land use in the region of Fenyőfői Osfenyves. On limeless sandy surfaces of the Bakonyalja (Nagytevel, Sümeg, Hegyesd, environs of Sáska and the margin of the Basin of Kál) basically only calciphobe sandy grasslands (Thymo angustifolio-Corynephoretum) are characteristic. The most characteristic, marker species in the stands are Corynephorus canescens, Rumex acetosella, Jasione montana, Thymus serpyllum, Hypochoeris radicata. * * * Acknowledgements -1 wish to thank BEÁTA PAPP, ISTVÁN GALAMBOS and LÁSZLÓ LŐKÖS for the identification of the mosses and lichens, and ZOLTÁN KENYERES for partaking in the field work.
