Epiphytic lichen cover and diversity were analysed in the oak-hornbeam forest in the
Olsztyn Lakeland. The mesoregion, covering ca. 4,000 km 2 , is located in the northern Poland,
in the impact zone of sub-oceanic and sub-continental climates. Thirty study sites, with the
constant area of 400m 2 , were sampled in the best preserved old-growth forest stand, situated
both within protected areas, with the nature reserve status, as well as within managed forests.
The sites were concentrated in three locations in the region (S, N and NE). At each site, all
lichen species on each tree up to a height of 2 m were identified. A total of 405 trees,
belonging to eleven tree species, were studied. A total of 130 lichen species were identified,
with a range between 17 and 58 species per site (average 45). The highest number was
recorded on Carpinus betulus with 103 species, followed by Quercus robur with 86 species,
Acer platanoides with 52, Tilia cordata with 50, and Fagus sylvatica with 37 species. Most of
the recorded lichens (80%) were crustose (104 taxa), while only 26 foliose and fruticose
species were recorded. The common lichen species were 19 taxa (occurring in 80% of the
sites), whilst the rare species (occurring in 20% of the sites) were 65 taxa. Out of the reported
species, 43% of the taxa (57 species) are red-listed, 12% are protected by law in Poland (15
species), and 25 species are considered to be the lichens-indicators of lowland old-growth
forest in Poland. Particularly noteworthy collections include: Caloplaca lucifuga,
Candelariella efflorescens, Cliostomum griffithii, Phaeophyscia endophoenicea and Pyrenula
laevigata. The results could provide a reference point (in a regional and supra-regional scale)
and a practical tool, both in assessing the state of conservation of lichen biota, as well as the
degree of transformation of meso-and eutrophic deciduous forests. It seems to be particularly
