Une nouvelle méthode d’étude des peuplements de lichens foliicoles

The authors propose a new survey method for the foliicolous lichen communities growing on Buxus sempervirens, based on the integral sampling but with account of the age of the phorophyte shoots. Three variants are studied, of which the analysis by substrate type is suitable to phytosociological surveys, whereas the analysis by age classes allows to accurately follow the dynamic of the foliicolous communities.
