Dry grass catalogue 1986 partial revision 2022/23

Revision, re-demarcation and re-mapping of dry grasslands in continental biogeographical region of Austria. Areas from the dry grass catalogue 1986 (Holzner 1986) were revised and supplemented by missing occurrences. Mainly dry grass of the following types were processed: 6210 Semi-natural dry grasslands and scrubland facies on calcareous substrates (Festuco-Brometalia) (* important orchid sites); 6130 Calaminarian grasslands of the Violetalia calaminariae; 6190 Rupicolous pannonic grasslands (Stipo-Festucetalia pallentis). The data come from a mapping carried out in 2022/23 within the framework of the project: Wolfgang Willner: Inventory and typology of dry grasslands in the Alpine biogeographical region of Austria, BMK Biodiversity Fund.
