Abstract
The distribution of the epiphytic macrolichen Lobaria pulmonaria (L.) Hoffm. was surveyed in the Regional Forest of Cansiglio, extending over 3,500 ha in the eastern part of the Veneto Pre-Alps (north-east Italy). Data on the main characteristics of the forest sites and on Lobaria trees were collected with the aim to evaluate the main ecological factors, related to forest composition and management, affecting the distribution of Lobaria pulmonaria. Lichen diversity was surveyed on 15 randomly selected Lobaria trees. A good correlation between macrolichens and the total number of species was found. The largest Lobaria populations are concentred in the north-eastern part of the forest, where mixed and multi-plane silver fir – beech formations prevail, and selective cutting is carried out. Our data has enabled us to develop some criteria for the identification of priority conservation sites for Lobaria pulmonaria and lichen diversity in the study area, improving the focus on biodiversity in the management of the forest.
