Abstract: Komposch, H. 2025. Does age matter? How tree age affects lichen diversity on beech trunks in a temperate forest.  Herzogia 38: 5  22.
This research uses indicator species analysis and non-metric multidimensional scaling to find out whether old trees harbor uniquely adapted lichens that are rarely found on younger trees. Two suitable old-growth forests were selected in the Gesäuse National Park in Austria and 54 beech trunks were examined for their lichen cover. Of the 112 identified lichen species, 30 % were red-listed species, including the two critically endangered lichens Agonimia allobata and Sticta fuliginosa, suggesting that the lichen communities of old trees and forests are of significant conservation interest. The study showed that species richness and diversity accumulate with increasing trunk diameters and decrease slightly after reaching a maximum width. NMS ordination showed that old or thick trees differed greatly in their lichen composition from young or thin trees. The indicator species analysis yielded a list of 11 species indicative of very old trees, including Lobaria pulmonaria and Chicitaea cristinae, a sterile lichen species recently described from an old-growth forest in Poland. Management measures are recommended to promote ancient forests that harbor these unique and endangered lichens.
