Sažetak
The alliance Lobarion pulmonariae Ochsner 1928 is the major climax community of epiphytes on trees in undisturbed and old-growth forests in Europe. It includes large foliose lichens of the genera Lobaria and Sticta, smaller foliose lichens of the genera: Fuscopannaria, Nephroma, Pannaria, Parmelia, Pecteniella, Peltigera, many crustose lichens, and a number of bryophytes. Based on checked literature records and lichen collections at herbaria in Croatia and abroad, and field surveys undertaken since 1990s, a distribution map of the alliance Lobarion pulmonariae in Croatia has been created. It shows frequent distribution in the montane belt of the Dinaric Mountain chain, and in the Middle and southern Dalmatia (at higher elevation in hinterland, near the coast of the Adriatic Sea and on islands), with a disjunctive distribution in the montane belt in the Pannonian region. Main climate conditions required for growth of lichens from the alliance are moderate light, high air humidity and annual rainfall above 1, 000 mm. It was found that distribution of Lobarion pulmonariae in Croatia overlaps with annual rainfall division, and is restricted by isohyet of 1, 000 mm. Among 13 host trees recorded for epiphytic lichens, the main species are: Fagus sylvatica, Acer pseudoplatanus, Quercus pubescens, Quercus ilex, Picea abies and Abies alba. Occurrence of lichens relates directly to the presence of old, large host trees and bark pH value. Mean tree circumference of host trees ranged from 106 cm to 179 cm ; maximum in Acer pseudoplatanus (390 cm), and Fagus sylvatica (363 cm). Bark pH was in optimal range, between 5.8 and 6.9. Epiphytic lichens make an important component of the total biodiversity in many forest ecosystems. Conservation measures are mainly related to forest management practice. It is important to reduce habitat disturbance and secure substantial number of retention trees, as well as to implement permanent lichenological monitoring.
