The study was conducted on Abies trees located in Kirazlıyayla - Sarıalan camping and daily picnic areas in the Uludağ National Park. The epiphytic lichen diversity decreases due to differences in microclimate and intensive use of picnic areas by people. Relative humidity and bark surface moisture decreased due to an increase in the amount of light in picnic areas. Relative humidity in Sarıalan picnic areas significantly affects the epiphytic lichen diversity and causes a significant decrease in lichen species. Relative humidity and light are the most important factors affecting the diversity and structure of epiphytic lichen.
