PROVISION OF ASPEN TREES OF MIDDLE TAIGA WITH UNDERGROWTH OF PREVIOUS GENERATION (ON THE EXAMPLE OF TOMSK REGION)

 Model territory for studying processes under rolagem forest resume was selected Verhneketskoe forestry of Tomsk region, situated in middle taiga subzone. Taiga forest fund of forest districts of the Tomsk region has large area under mature and overmature stands of deciduous trees. The area of forests aspen is 88 %. The last indicates of a need for active development of aspen forests to prevent loss of wood due to natural mortality of trees. The article deals with distribution of areas covered with forest vegetation according to prevailing there woody species on the example of Verhneketskoe forestry of Tomsk region. It is noted that when the share of broadleaved standing trees constitute 25 % then the share of derivative aspen trees constitutes about 21 %. 88 % of aspen trees are represented by mature and over mature forest stands. Aspen stands are characterized by average density 0.6 and average yield class III. For all this 79 % of aspen trees are represented by heavy green group of forest types. The most part of mature and premature aspen stands are secured by coniferous undergrowth of preliminary generation in a number sufficient for subsequent reforestation in the process of aspen stand cutting out and provided the undergrowth is preserved in the process of cutting work carrying out. The second layer of spruce, fir, Siberian pine well as large undergrowth of dark coniferous species gives hope for reforming derivative aspen stands into basic coniferous ones trees without artificial reforestation. High potential ability of aspen for vegetative regeneration calls for necessity to study natural forming of undergrowth on cutover areas in condition of the undergrowth of preliminary generation preservation as well as for lack of it.
