Lichens of natural reserves Jazevčí, Porážky, and Zahrady pod Hájem in the Bílé Karpaty Mts (Eastern Moravia)
Abstract
128 lichen taxa were recorded within the course of the lichen biodiversity survey in three natural reserves in White Carpathians (Jazevčí, Porážky, Zahrady pod Hájem) in 2011. The most important records are epiphytes Buellia disciformis, Caloplaca cerina, Evernia divaricata, Graphis scripta, Parmelia submontana, Parmelina quercina, Phaeophyscia endophoenicea and Pyrenula nidita, saxicolous Lobothallia alphoplaca and Rhizocarpon petraeum, and terricolous Leptogium schraderi.
Some overlooked microlichens (e.g. Agonimia repleta, Caloplaca obscurella, Macentina abscondita, Ramonia interjecta) were recorded.
The lichenicolous fungus Sarcopyrenia beckhausiana is new to the Czech Republic. The Jazevčí reserve with 90 species is the richest surveyed locality in lichen taxa.
Localities in White Carpathians are quite poor in lichens because of (a) lack of suitable substrates (meadows and young shaded forests prevail), (b) acid rains in the past, (c) eutrophication in the present, intensive farming in the surrounding landscape, and (d) arid climatic conditions. Majority of recorded lichens were observed on solitary trees, in abandoned orchards, and in edges of forest fragments.
Calcareous sandstone/claystone boulders, spots of exposed calcareous soil and decaying wood are rare but important substrates in surveyed territories.
