摘要

Stability of forest ecosystems is a common goal of forest management and nature protection. Stability is given when the populations of the involved forest tree species are persistent. Persistence of population results from its current state of adaptedness and from its adaptive and reproductive potential which due to seed stock. A study of some populations of Abies sibirica Ledeb. in the middle mountains of East Sayans demonstrates that seed-consumer plays a decisive role in the loss of fir seed stock. It was established that extent of seed elimination by the seed-consumer highly depends on initial amount of full seeds in stand, location of stands and features of the biology of seed-consumer. For the first time it was established that fir seeds are damaged by Megastigmus specularis Walley only.
