Contribution to the Knowledge on Lichen Diversity of Kopački rit (Croatia)

Seventheen lichen species were recorded during the preliminary survey of the epiphytic lichens in Kopački rit Nature Park. They were collected from the various trees and bark pH values were measured. The most common species were Physcia adscendens and Xanthoria parietina. Nitrophilous lichen alliance Xanthorion parietinae is widespread due to natural enrichment of habitus by nitrogen compoundsoriginated from animal excrements. The increasing of the phorophyte tree bark pH value caused by dust impregnation with allogenic nutrients and ammonia enables the settlement of the nitrophilous lichens. The ecological conditions near the oak forest-edge in Tikveš area supports more higrophylous lichen species.
