摘要：Lichens are one of the prominent taxonomical indicator groups for changes in forests. Within the course of the research project BIOKLIM, we sampled 125 epiphytic lichens, 5 lichenicolous fungi, and 1 non-lichenized ascomycete in wilding areas, managed areas, and relicts of old-growth forests along four transects in the Bavarian Forest National Park. Our analyses showed that old-growth relicts and wilding areas have a significantly higher diversity and a higher number of red-listed species than managed forests, demonstrating the importance of these areas for the protection and dispersal of endangered lichens and lichenicolous fungi. The rare and threatened lichenicolous fungi Chaenothecopsis viridialba, Sphinctrina anglica , and Sphinctrina turbinata and the critically threatened lichen Mycobilimbia sphaeroides were new records for the Bavarian Forest. The lichen-fungus Sphinctrina tubiformis , presumed extinct in Germany, was recovered in the old-growth relict Rachelseeurwald. The following species were classified as indicators of old, nearnatural forests of the Bavarian Forest: Lecanactis abietina, Pyrenula nitida, Micarea cinerea, Microcalicium disseminatum, Loxospora cismonica , and Thelotrema lepadinum . We propose management implications for the managed areas of montane and high montane forests in Central Europe.
