Lichens to monitor afforestation effects in Çanakkale, Turkey

The lichen flora of two mountains in western Turkey was investigated: of 124 species recorded, seven were new for Turkey: Aspicilia mastrucata, Calicium quercinum, Chaenotheca phaeocephala, Fuscidea praeruptorum, Psilolechia lucida, Rhizocarpon badioatrum and Trapelia obtegens, and 70 taxa were new for the Çanakkale province. For 6 of 7 indicator values figures, it is clear that the lichen fioras of an old forested mountain and a freshly afforestated mountain are significantly different, with only the temperature values showing no apparent difference. Lichens are therefore good indicators to follow the effects of forest management.
