These forests were formed as a result of felling of primary forests. A second growth of mountain river’s water catch deprived of his protective properties of primary forests. It increases the risk of waterflood during the precipitation with high intensity. In the second growth, is determined the dry weight of forest litter and grass cover. The first value (10 t/ha) is lack of interflow during the intensive precipitation, the second value (3, 25 t/ha) is no soil erosion. In addition, we have identified the following values that characterize the lack of soil erosion: the content of organic matter in the topsoil (? 7,6%), the coefficients of porosity (? 1,33), yield of strength (? 53%) and angle of internal friction between soil particles (? 22°). Infraction of these critical values leads to the formation of interflow and soil erosion during heavy rains. The results of this studies can explain why the soil erosion in the forest occurs during the periods of intense of precipitation. It leads to bottled mountain rivers. It substantiates measures to protect soil from erosion in the second growth. These measures should ensure prevention of soil degradation and accumulation of forest litter under the forest canopy.Authors1V.M. Ivonin, Doctor of Agriculture, Professor2 A.V.
