THE CONDITION OF COENOTIC POPULATIONS OF TILIA SIBIRICA BAYER, 1862 IN KEMEROVO REGION

Abstract

Monitoring researches of populations of rare species are necessary for assessing the dynamics of their state and developing the measures for preservation of biodiversity. The purpose of this work is to estimate the condition of coenotic population of Tilia sibirica Bayer growing in the kernel of its areal. Locations of coenotic population were recorded by geographical coordinates with an additional binding to the next settlement. For the characteristics of habitats, typical geobotanical descriptions with the indication of structure and species composition of the phytocoenosis were performed When studying landings of T. sibirica, the area of coenotic population, the age of trees and their vitality on the trial platforms of100 sq. m. chosen by envelope method were determined. Cut virginile trees were found. In the territory occupied by the Siberian linden coenotic populations of various vital states (equilibrium, prospering and depressive) were discovered. It gives a reason to make the assumption that in case of taking appropriate measures (sanitary cutting down of trees, rational use of the wood received at cutting down of trees) preserving and increasing the number and quality of the condition of linden population is possible.
