Abstract Lichen community changes were investigated on trees within a colony of great cormorants ( Phalacrocorax carbo sinensis ) established in pine forest the Curonian Spit, western Lithuania. The impact birds has altered number and characteristics substrata available to lichens. lowest lichen species occurrences was registered most active part with highest nest density. patterns strongly related P Ca content pH values. Some acidophytic showed negative correlations, both long-term short-term ornithogenic influence. However, three acidophytes Chaenotheca ferruginea, Lepraria incana, Coenogonium pineti demonstrated an affinity for transitional zone recently occupied trees, furthermore, C. apparently reacted positively influence but negatively one. These lichens, along algae, main, often only, components epiphytic communities at edge indicated crucial point under increasing load nutrients. All nitrophytic bird Only free-living algae (predominating Desmococcus olivaceus clear by nests. Hypogymnia physodes found be indicator early environmental following eutrophication. study also that high concentrations did not have mitigating effect detrimental brought about increases N levels, possibly equally
