This survey was mainly focused on epiphytic lichens, but some collections were carried out also on dead wood. Eighty-four species, including two non lichenized fungi, were found. The ecology of the species reflects the features of the forest habitat, most of them being linked to acidic substrates, preferring intermediate and well-lit conditions, intermediate moisture conditions, and avoiding eutrophication. Keywords: coniferous forests, dead wood-dwelling lichens, epiphytic lichens, forest management 1 Introduction Lichens are a symbiotic association of a fungus with a photosynthetic partner, which is either a green alga or cyanobacterium. They are a species rich component of the forest biota, occurring on many substrates including trees, bare rocks and exposed soil surfaces. Epiphytic lichens growing on tree trunks and branches play an important role in the forest ecosystem functioning. They affect water-cycling by retaining precipitation in the canopy, and cyanobacterial lichens influence nutrient cycling by fixing atmospheric nitrogen. They are a crucial component in forest food-webs, increasing microhabitat complexity and diversity of forest invertebrate fauna, which in turn serves as food for a variety of passerine bird species. Along with climate and air pollution, forest management is a key direct control of epiphytic lichen diversity in forest ecosystems (JOHANSSON 2008, ELLIS 2012, NASCIMBENE et al. 2013). Diversity of epiphytes is related with forest structure and dynamics, and several environmental factors relevant to their dispersal, establishment, and maintenance are affected by forest management. The studies on lichen diversity clearly demonstrate dramatic losses of species caused by forest management in European temperate and boreal forests. The main negative effects of forestry are related with lack of old trees, short rotation cycles, excessive canopy cover, or excessive exposure to direct light in the final part of the rotation cycle, lack of substrate particularly for dead-wood dwelling species, decrease of structural diversity, lack of forest continuity, and forest fragmentation. 5 J. NASCIMBENE: The epiphytic lichen flora of “Großer Zirmboden”, Latemar, South Tyrol In this framework, a research project started in 2011 in South Tyrol to investigate the effect of climatic and management-related factors on the distribution of epiphytic lichens in mountain forests (NASCIMBENE et al. 2012). In particular, this study summarizes the results of a lichen floristic survey carried out in a 4 ha forest plot as a preliminary phase of a research on the small scale distribution patterns of some selected species. This floristic information was used to select appropriate species with contrasting dispersal strategies, growth forms and ecological requirements (ACKERMANN 2012) to retrieve information on the relative importance of habitat features and dispersal dynamics in determining the distribution of epiphytic lichens within forests. 2 Materials and methods 2.1 Study area The study site is a 4-ha permanent plot located on the Western side of the Latemar massif in the Western
