The proposition of optimal silvicultural-reclamation operations in untended beech stands of mixed origin

The state, quality, spontaneous development and silvicultural demands of untended beech stands of mixed origin were studied, the age of trees in the dominant layer is about 75 years. The analysis of stand development through a 17-year period (1986-2003) included the monitoring of the elements of stand structure: Number of trees, basal area, volume, diameter and volume increment, mean stand diameter, structure, mortality and tree removal from the stand, morphological, biological and technical characteristics of trees and biological differentiation of trees. The adequate silvicultural-reclamation measures are proposed based on the identified stand state. U radu su prikazani rezultati istrazivanja stanja, kvaliteta, spontanog razvoja i uzgojnih potreba u nenegovanim sastojinama bukve mesovitog porekla, starosti stabala dominantnog sprata oko 75 godina. Analizom razvoja sastojine u sedamnaestogodisnjem periodu (1986-2003. god) pracena je promena elemenata izgradjenosti sastojine: broja stabala, temeljnice zapremine, debljinskog i zapreminskog prirasta, srednjeg sastojinskog precnika, strukture, mortalitet i izlucivanje stabala iz sastojine morfoloske, bioloske i tehnicke karakteristike stabala i biolosko diferenciranje stabala. Na osnovu utvrdjenog sastojinskog stanja predlozene su odgovarajuce uzgojno-meliorativne mere.
