The open pit mining of coal production prevails in the Kuzbass region. As a result of coal mining there is a land relief change, soil disturbance, which leads to the change of biogeocoenosis as a whole. The choice of forest cultures being able to create the dumps productive plantations is restricted substantially. In Kuzbass one of the few tree species suitable for afforestation of degraded lands Pinus sylvestris L. is. The study of the anatomical and morphological parameters of Pinus sylvestris L. of different age in the conditions of the Kedrovsky coal cut was carried out. Some changes in the anatomical structure of pine needles of the investigated plants of adaptive character were noted. It was revealed that trees 10-15 years of age had higher rates of the square of the central cylinder, conducting bundles, pitch channels and the relationship of the areas of the central cylinder to the transverse shear, than the trees 20-25 years of age. Pinus sylvestris L. growing in the planned dumping site without application of the potentially fertile soil layer has the maximum number of anatomical alterations of pine needles contributing to its survival in extreme environmental conditions.
