The species richness and composition of epiphytic lichens were evaluated on trunks of Fagus sylvatica
in primeval beech forest stands of the Carpathian Biosphere Reserve (Ukraine). A total 327 forest sampling plots
were investigated. On each sampling plot we observed lichens on different age classes of trees with a special
focus on veteran trees. The environmental variables such as development stage of forest, canopy closure,
northing, easting and inclination of the slope and natural and anthropogenic forest stand disturbances, were
measured on each sampling plot. More than 195 lichen species have been listed so far. Crustose lichen species
are amongst the most frequent species and include Phlyctis argena (95.1%), Graphis scripta (91.4%), Pyrenula
nitida (87.2%) and Lepraria lobificans (78.6%). The highest number of lichens was recorded on beech trees,
which grow near the subalpine timberline in mature or overmature forests. Young forest stands have the lowest
number of lichens (up to 5). In mature or overmature forests at the bottom of valley or on the lower part of the
mountain slopes an characteristic lichen richness of 6-14 species was observed while on the upper part of the
mountain slopes and on mountain ridges 15-25 lichen species were recorded per each plot. We found 12 lichen
species which are included in the Red Data Book of Ukraine (2009) e.g. Belonia herculina, Gyalecta truncigena,
Heterodermia speciosa, Leptogium saturninum, Lobaria amplissima, L. pulmonaria, Melanohalea elegantula,
Nephroma parile, N. resupinatum, Pannaria conoplea, Parmeliella triptophylla and Parmotrema perlatum. Primeval
beech forests were found to shelter a relatively low average species richness but to harbour a high number
of rare and endangered epiphytic lichen species.

LICHEN FLORA OF ILAM PROVINCE, SOUTH WEST IRAN AND
ITS BIOGEOGRAPHICAL SIGNIFICANCE

Ilam province, part of The Zagros Mountains, contain several ecosystems. Prominent among them
are the forest area. From the whole 160 lichen species of this area, 114 species are recorded as new to Ilam
province, and two species, Lecanora sulphurata (Ach.) Nyl. and L. klauskalbii Sipman are new to Iran. It is very
probable that The Zagros Mountains forest steppe harbour an interesting lichen flora, but so far they have been
hardly explored. A regional specialty may be the species Pyrenula subelliptica (Tuck. in Lea) R.C. Harris, which is
mainly known from eastern North America and appears to be restricted in the Old World to the Euxinio-Hyrcanian
region, as suggested by Some other North American element as Lecanora juniperina and L. percrenata and a
tropical element as Pyrgidium montellicum (Beltr.) Tibell and the recorded new species of Megaspora rimisorediata
Valadbeigi & A. Nordin are indications for the lichenological significance of this region.
