Lichens growing on Abies alba in the Karkonosze National Park (South West Poland) – the results of the first stage of the conservation program [Kerpės, augančios ant Abies alba Karkonošų nacionaliniame parke (Pietvakarių Lenkija). Pirmosios apsaugos programos pakopos rezultatai]. – Botanica Lithuanica, 9(1): 65–70.

The paper presents the results of the first stage of a conservation programme of lichens growing on silver fir (Abies alba) in Karkonosze National Park. The present lichen flora of this phorophyte comprises 43 species. Widespread, toxitolerant species, e.g., Lecanora conizaeoides, Scoliciosporum chlorococcum, Hypocenomyce scalaris, and H. caradocensis predominate; more sensitive lichens occur only in small, isolated refuges dependent on local environmental conditions. In the next stages of the conservation programme, changes in the lichen flora will be monitored, and reintroduction experiment will be implemented.
