Sažetak
Criteria for evaluation of stand vitality and exposure topressures are main part of the " Methodology for determining and monitoring the state and changes of forest ecosystems and the resulting damages and losses". For stand vitality evaluation two groups of diagnostic parameters were established: (1) regeneration capacity: a. Potential reproduction (flowering and seed crop periodicity, seed crop quantity, seed quality, young growth frequency), b. potential survival (pedogenetic and technogeneic characteristics of the upper soil layer, coverage, critical pressure of large herbivore, small animals and birds, and the quality of young growth) ; (2) stand growth and development: a. height, diameter and volume increment, development of tree crowns and Wood assortments, b. Physiological disturbances (pedogenetic and technogenetic characteristics of inner soillayers, crown and stem injuries, intesity o pest attack and diseases). Stand state and change indicators were quantified (by point system, indices' 1-9) and classified by quality categories (1-9, from insufficient to excellent). Evaluation of stand vitality was carried out for two Ecological- Managerial Forest Types (EMFT) and results are. For EMFT that is represent by association of Common Oak and Hornbeam the stand vitality decreased for 6%, growth and development capacity decreased for 5.8%, stand regeneration capacity is 67.1% of its potential, and the average income loss is 11.5%. For EMFT that is represent by association of Common oak and Great Greenweed stand vitality was not changed.
