Epiphytic lichen phytomass distribution on the scotch pine (Pinus sylvestris L.) stems and branches

An attempt to estimate the epiphytic lichen phytomass on the Scotch pine (Pinus sylvestris L) stems and branches is taken. It is determined that the epiphytic lichen phytomass on a Scotch pine varies from 130 to 1090 g. Lichens of the Bryoria (45 %), Hypogymnia (34 %) and Evernia (12 %) species bring main contribution. Epiphyte phytomass makes 96 % from whole mass on the tree branches. The most part of lichens (66 %) has been found in the zone of the greatest branch development (at height of 9-13,5m). The epiphytic lichen phytomass on the tree stems is very small (4 %) and concentrated in the stem basis on 70 %.
