Implemented environmental safety assessment forestry and forestry activities at the constantly operating scientific facilities of the NULES of Ukraine “Boyarska FRS”. It was found that the way of preparation of cutting down, significantly affects the abundance of living ground cover, structure of the upper soil horizon, survival rate, growth and development of forest crops in different phases of growth. It was noted that changes in soil conditions caused by mixing of genetic horizons, which are manifested in the growth of forest crops, especially after the completion of the phase of individual growth. Studied the influence of various methods of preparing log houses for afforestation and an assessment of the impact of each method of preparing cutting down on the environment. It is established, that the average heights and diameter of 38-yearold forest pine on control exceed the similar indicator of crops in areas with the stitching of hemp by 1.5 m and is 14.0 and 12.5 m respectively. Preservation of forest plantations on the reduction of stumps, stump rooting, tree felling and control is 52.4%, 66.7, 38.1 and 50.0%. It was found that the composition of the biodiversity of the living ground cover on the variant with cutting cuttings at the level of the earth’s surface is the largest and is 95 thousand pieces/ ha, and on the felling of trees with roots there are only ruderants that are not characteristic of the forest cenosis plantingsfresh pinetum compositum Kyiv Polissya.
