video survey, digital satellite survey and three-dimensional taxational computer analysis of images. On its basis regularities of taxational structure and dynamics of phytomass in plantations forming after fires and cuttings were found out. Two receiving and analyzing satellite information stations available at the Institute make it possible to estimate ecological information in real time in the interests of various institutions. In cooperation with foreign scientists the Institutes is working out the system approach to forest management with the help of GIS technologies and databases characterizing the main components of forest biocenoses. On the basis of modern techniques of receiving and analysis of scientific information estimation of ecological condition of forests in the zones of huge technogenic impact (oil-gas complex of West Siberia, Norilsk industrial region) is carried out. In two dendrariums of the Institute for more than 30 years about 450 species, subspecies and forms of trees and bushes from different botanico-geographical regions have been investigated. Their acclimatization, growth and development in new conditions are estimated to select perspective species for planting of greenery in towns and other settlements. Long-term investigations of Siberian forests are reflected in more than 450 books and collections of papers of the Institute employees. The information about features of forest forming process contained in them is widely used by home and foreign scientists and design organizations. On its basis normative documents (rules, directions, recommendations) regulating the main forest production works in Siberia.
