The effects of picnic areas on epiphytic lichen diversity at abies forests in Uludag National Park, Turkey

Abstract

The study was conducted on Lambda bie,s' trees located in Kirazliyayla - Sanalan camping and daily picnic areas in the Uludag National Park. The epiphytic lichen diversity decreases due to differences in micro climate 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 San alan 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.
