Description Flora, vegetation and habitat conditions of a rare type of wetland occurring on serpentine bedrock near Bory village by the town of Velké Meziříčí are described. The fen meadow harbours many basiphilous species of vascular plants (e.g., Blysmus compressus, Carex distans, C. paniculata, Eriophorum latifolium) and mosses (e.g., Cratoneuron fi licinum, Dicranum bonjeanii, Scorpidium cossonii), otherwise rare in the region of Bohemian-Moravian Highlands with prevailing acidic bedrock. The vegetation was classified to Caricion davallianae alliance and Campylio stellati-Caricetum lasiocarpae association, though some characteristic species of the alliance are missing. This may be ascribed to the specific chemistry of the serpentine bedrock and the geographical isolation of the site. Soil pH ranges between 6.7 and 7.1 and ground water conductivity exceeds 500 microS/cm, equalling the values for the extremely rich calcareous fens. Despite high conservation value, the site is not legally protected and has recently been seriously damaged by the owner.
