Abstract: [Study on pine trees with nitrophytic lichen vegetation, especially Xanthoria parietina and Hyperphyscia adglutinata. "Tree circumference, distance from the stock farms, bark pH and bark electrical conductivity emerged as the main factors influencing the distribution and abundance of epiphytic lichens in the study area."]
