Regeneration process in virgin pine woods of foothills Ural mountains of the basin Pechora river

Research was carried out in flat and foothills landscapes of the Ural Mountains in Pechoro-Ilychsky Reserve. The natural regeneration-process in mature and over-mature pine woods of different types is characterized. The undergrowth density changes from 0,9 to 21,5 thousand ind. ha -1. Correlations between undergrowth density and forest type and that between undergrowth density and stand normal stocking were not identified.
