The dynamics of forest inventory indicators, attrition and wood growth of 35yearold pine Рinus sylvestris L. crops with various density are analyzed, Pine crops were created in 1982 by V. N. Sukachev Institute of Forest Russian Academy of Sciences, Siberian Branch under the leadership of A. I. Buzykin on former agricultural lands in Bolshemurtinsky district of Krasnoyarsk Krai. The initial density of the stands varied in a wide range from 0.5 to 128.0 thousand trees per ha. The assessment of the stand density influence on the growth and productivity of young pine stands at the age of 2, 5, 12, 15, 20, 25, 30 and 35 years old was carried out. It has been established that since the age of five, the process of intensive selfthinning of trees has been observed, at initial planting density 90.0 thousand trees/ha the density decreased to 10 thousand trees/ha by the age of 35 years. At the initial density less than 10 thousand trees/ha the selfthinning intensity is significantly lower and the stand density has decreased by less than 2 times over the same period. It is shown that at the initial stage of stand growth there is a growth increase with the initial planting density, reaching the plateau at a density of over 70.0 thousand trees/ha. With age reaching the plateau occurs with the lower initial density.
