Abstract
Research results on the spatial placing and quality of natural regeneration in interterrace space of protective reclamative stands of Pinus sylvestris on the benched slopes of carbonate rocks of the Lugansk region are reported. Age-class composition of natural regeneration of Pinus sylvestris in investigated plots of carbonate slopes is presented by self-seeding up to 1 year-old, which is the least, biennial seedlings, triennial and 4–8-year-old undergrowth, the last has the most spread. Percentage of reliable regeneration differs in sample areas with different conditions. In the plot with slope 20 it varies from 81 to 92 %, in the plot with slope 35 it varies from 39 to 86 % in the sample mini-plots. Reliable regeneration is presented by biennial self-seeding, small triennial and middle 4–8-year-old undergrowth. Progress of natural regeneration in sample areas is satisfactory.
