Birch stands of the Eastern Polissya: structure, health condition and productivity
Journal Title: Лісівництво і агролісомеліорація - Year 2016, Vol 129, Issue
Abstract
The article considers the structure and the features of formation of birch stands in the Eastern Polissya of Ukraine. The analysis of health condition as well as the comparing of the actual productivity with tabular data for birch normal stands was carried out. It is shown that the age structure of birch stands is not optimal due to an area exceeding of mature and overmature birch stands and deficiency of young stands. In the initial stages of birch forests formation, the birch dominates along with other small-leaved species. With aging, the participation of birch in the composition of the secondary stand increases. The health condition of birch stands is deteriorated with age increasing and decreasing the birch participation in the stand composition. The actual productivity of birch forests is about 80 % of stand volume with the density of birch stocking 1.0. The technical quality of the wood of mature birch stands refers to the 2nd and 3rd merchantability classes.
