Abstract
The article dwells on the condition characteristic of forest crops and the natural regeneration of Scots pine (Pinus sylvestris L.) on the rock dumps of the Kumertau lignite strip mine. According to the relative vital state of the pine plantations, the pine stands are classified as “healthy” and have been successfully bearing fruit for a number of years. Fallen seeds provide a natural regeneration of pine on the rock dumps. The success of seed regeneration of pine depends on the degree of development of herbaceous vegetation — successful natural regeneration was noted in areas with a low proportion of herbaceous vegetation. In general, the pine tree fruiting ensures regeneration in the amount of at least 5000 pieces per hectare, which is sufficient for the formation of full-fledged pine stands on rock dumps.
Key words
Scots pine, forest crops, natural regeneration, recultivation, rock dumps.
