Abstract

Building a rational risk management system for natural emergencies requires a special assessment of the resilience of forest ecosystems to external influences. The stability of ecosystems is the ability to maintain balance under the influence of external factors, in other words, to overcome changes without disturbing basic properties. The sustainability of forest ecosystems is analyzed in terms of the main forest-forming species exposed to natural and anthropogenic factors. Natural influencing factors include climatic ones, which cause changes in forest conditions as a result of changes in temperature and humidity characteristics. Anthropogenic factors are varied and include logging, drainage, recreation, and forest fires. Groups of factors influencing the stability of forest species, leading to defoliation, damage and death of trees, have been identified. For the first time, a point scale for the sustainability of the main forest-forming species has been proposed, which is based on the use of the method of statistical information processing, as well as the method of expert assessments. Based on the analysis, it was revealed that the least resistant species are coniferous species, namely spruce and pine. Among deciduous species, the condition of oak and birch is of concern. The proposed approach is a structural element of the methodology for assessing the resistance of forest ecosystems to the occurrence of emergency situations.
