CONCEPTUAL ISSUES OF SILVICULTURAL MEASURES FOR SPRUCE FORESTS SUSTAINABLE MANAGEMENT

Abstract

Introduction. The problem of constant Bark beetles attacks in spruce forests and loss of valuable coniferous stands demands the analysis and classification of a number of factors provoking spruce forests damage. The goal of the research is to elaborate the general silvicultural conception of spruce forests management and to increase their resistance to the pathological factors. Methods. The analysis of many researches and elaborations is at the heart of the conception development. The conception was developed on the basis of a systems top-priority-target method. Silvicultural measures were successively interconnected along the cycle of spruce forests regeneration. Results. The factors of spruce plantations damage (climatic, biological, and humancaused) were revealed. The conception for silvicultural measures improvement with the aim to improve their vitality, and to diminish negative consequences when Bark beetle mass propagating, was elaborated. It was elaborated on the basis of assessment of potential and real managerial impact on the performance of the main factors for spruce forests dying. Conclusions. The conception for silvicultural measures improvement in spruce forests to improve their vitality and to diminish negative consequences when Bark beetle mass propagating was elaborated. The developed silvicultural measures will assure the solution of the problem if systematic and timely application aimed at spruce forests conservation and sustainable forest management.
