Lišajníky biosférickej rezervácie Východné Karpaty

Preliminary report on the lichen flora of the Biosphere Reserve Východné Karpaty (NE Slovakia), is presented. In total 208 species is recorded (62 of them belong among threatened). Several species very rare in other parts of Slovakia were found: Lecanora cinereofusca, Thelotrema lepadinum, Lobaria pulmonaria, Normandina pulchella, Menegazzia terebrata, Gyalecta flotowii, G. ulmi. Though suitable conditions for development of epiphytic and epixylic lichens (132 taxa) are still present in the Reserve, decrease of sensitive indicators of natural mountain forests is evident.
