Contribution to the knowledge of lichen flora of Rašeliniště Jizery and Rašeliniště Jizerky (Northern Bohemia)
Abstract
98 lichen taxa were recorded in the protected area Rašeliniště Jizery and 104 in the Rašeliniště Jizerky National Nature Reserves in Jizerské hory Mts in 2013. The most important records are Acarospora glaucocarpa, Ionaspis lacustris, Micarea turfosa, Mycoblastus sanguinarius, Ochrolechia cf. alboflavescens, Porpidia hydrophila, Rhizocarpon badioatrum, R. lavatum, Thelomma ocellatum, and Verrucaria cf. sublobulata.
Majority of recorded lichens were observed in old-growth peaty spruce forests and on granodiorite boulders in the valley of Jizera River. The epiphytic lichen flora was strongly influenced by acid rain in the past; trees are now occupied mostly by common acidophilous lichens.
Keywords: acid rain influence, biodiversity, peat bogs, peaty spruce forests.
