Rating assessment of the environmental and economic compositions of forest stands on the stage “cutting – forest renewal”

Abstract

The article deals with impact of cuttings on the composition structure of forest stands. The biological composition is represented as a species structure and origin of the stand, undergrowth, forest habitat functions. The economic composition is complemented economic efficiency and rotation periods. The proposed list of indicators rating estimation. Indicators are quantitative expression in points (0 ≤ 2). A rating estimation to be mature stands before cutting and cutting result and regeneration. The Technique of rating estimation approved by the results of cutting on experimental sites (total of 10) of the Department of Forestry. Executed it possible to reveal element wise assessment results cutting and forest renewal. Established objectivity planned and executed cutting the ways and renewal. Analysis of assessment results show big variations in integrated rating. For example, for a given sample of 10 plants rating stands before cutting varies from 5 to 9 points. Rating results cutting and forest renewal varies from 4 to 10 points. Change the rating stands under the influence of cutting fixed with its decline (up to 3), unchanged (0) and higher (≥1 ≤ 4). The technique is an objective basis for the selection of effective forest management decisions at the stage of “cutting – forest renewal”.
