Аннотация: In the territory of industrially advanced regions in Central Siberia, large-scale industrial and civil construction as well as building of motor roads and railways requires considerable amount of construction and road stone. The Krasnoyarsk Territory and Irkutsk Region, alone, have twenty six crushed stone quarries with an overall area of 580.1 ha at deposits of granite, limestone, porphyrite, keratophyre and marble. The monitoring using the tools and resources of remote sensing has revealed negative trends in recovery of natural vegetative ecosystems at mined-out and operating crushed stone quarries. Natural recovery processes have resulted in regeneration of young forest ecosystem over the overall area of 90.7 ha. The field researches have specified the structure of forest ecosystems and determined specific weight of species of mixed forest and taiga at the close vicinity of examined quarries. The area at all quarries is dominated by pine, birch is in the second place, and poplar and quaking asp share the third position. Larch, willow shrub formation, fir tree and cedar make 5.6 % of the population of all trees growing in the quarries. The factors influencing number of tree groups in the quarries are determined. The principal effect on the forest population is exerted by the geographical orientation of a quarry relative to cardinal points; the annular rate of forest yield is affected by the presence or absence of a fertile mixture composed of soil layers and overburden. All quarries are conventionally placed into two groups with respect to conditions of generation and growth of forest ecosystems: lateral geometry and number of spoil banks. The remote sensing has detected quarry sites where local forest ecosystems have generated. The article puts forward a package of measures aimed at enhancement of ecological efficiency of natural forest recreation in the areas of mined-out quarries.
