In this work, in the reservation groups of geobiocoenoses types 4 B 3 -- Fageta typica, 4 BC 3 -- Fageta aceris, 4 C 3 -- Tilia-acereta fagi were found. Average diameter at bend height for beech forest in the main stand is 34 -- 91 cm and height is 22 -- 32 m. Norway spruce average values are 23 -- 34 m height and 41 -- 87 cm thickness. Sycamore average values are 19 -- 31 m height and 24 -- 66 cm thickness. Beech achieved average values at stand basal area on plots from 17.7 to 28.6 m2/ha from the total stand basal area, which is 31,7 -- 43,6 m2/ha. The trend that on the more nitrophilous and hydric plots within the same altitudinal vegetation zone are beech individuals higher was confirmed. The assumption of decreasing growth of beech forest with higher slope and altitude was confirmed. For Norway spruce, sycamore and beech forest on the drier stand a greater spacing was confirmed. The consideration about the dispersion of individuals scattered trees in the reservation due to the spontaneous development of tree populations was confirmed and also was found that the protruding bedrock can diffuse dispersion change to random dispersion

This final work focuses on the valorization of self-sowing vegetation in abandoned agricultural land by the medium of phytosociology notes and dendrologic metering. The aim of the final work is to recondition of abided phytocoenological lands from 90 years of the 20th century and to give them effect by forest-typological difference. The results of this comparasion give a definition for trend of growth vegetation. It was confirmed by the effect of succession that mass of grass meadow kinds which are in the notes from 1995, are not exist but it is bringing to bear more of forest kind like are beechwood and nitrophilous varieties. From wood species enter pioneer tree species like are common hazel and trembling popolar. The mine wood species of location are littleleaf linden and durmast oak. The general advance of phytocoenosis is changing from grass and lighter forest ecosystems to shadowed, dampy forest community. By the forest typology this land we can include in 4th of altitudinal zone of forest at which the major part of inscriptions are in classification group of forest types 17 typical beechwood. Another group of forest types with minor representation is result of the major existence of nitrophilous varieties on the profuse talus lands.
