Among the listed species, Candelariella reflexa, Chaenotheca brunneola, Placynthiella icmalea, Usnea diplotypus and Usnea subfloridana have been already first reported for Croatia. The field survey was carried out at 14 collection sites in the periods 1997-1998 and 2001-2002. Floristic composition, life form spectrum and substrate preferences are described. The most numerous genera are Cladonia, Pertusaria, Lecanora and Peltigera. Lichens growth on 16 various substrates, among which the deciduous trees, Acer pseudoplatanus and Fagus sylvatica dominate. The alliance Lobarion pulmonariae, consisting of some rare and old-forest indicator species, is present within the area. [ABSTRACT FROM AUTHOR]
