Ungethüm, K./ H.-U. Kison/ R. Stordeur 2011: Die epiphytischen Flechten in drei verschiedenen Laubwaldgesellschaften im Nationalpark Harz [The epiphytic lichen flora in three different deciduous forests in the Harz National Park]. - Hercynia 44(2): 191-210. [RLL List # 226 / Rec.# 33689]
Keywords: Characteristic species/ Dead wood/ Deciduous forests/ Ecological requirements/ Epiphytic lichens
Abstract: During the course of lichen mapping in the Harz National Park in April and May 2009,15 plots of 400 m2 in three different deciduous forest communities have been examined, and resulted in 43 documented epiphytic lichen taxa. 25 taxa have been found in the Luzulo-Fagetum, and four in the Asperulo-Fagetum. The Tilio-Acerion is characterised by the highest lichen diversity, with 31 documented taxa. Based on the frequency of occurrence, particular lichen species are proposed as characteristic species of the forest communities concerned, in the two beech communities above all Porina aenea and Coenogonium pineti, and in the Luzulo-Fagetum in addition Mycoblastus fucatus. Hypogymnia physodes and Chaenothecaferruginea are confirmed as characteristic species for the Tilio-Acerion and in addition Parmelia saxatilis is proposed. Furthermore, it is proposed to delete the toxitolerant species Lecanora conizaeoides from the list of characteristic species of the three forest communities concerned. 13 species of the 43 species in total belong to the Red Lists of Sachsen-Anhalt, Niedersachsen and/or Germany in general. 47% of the lichen species, i.e. about half of the species, inhabit dead wood. Hence, dead wood has to be considered as an important structural element in nearly natural forests as habitat for epiphytic lichens.
