DYNAMICS OF REESTABLISHMENT OF VEGETATION IN AN ANTHROPOGENICALLY DISTURBED SPHAGNUM BOG IN THE TERRITORY OF AN OIL-FIELD IN THE MIDDLE OB REGION

Total coverage and coverage of individual plant species were estimated four times during six years in a sphagnum bog, which experienced a st rong anthropogenic impact five years prior to the beginning of the stu dy. No signs of the recovery of primary communities were revealed. Slo w process of the formation of a new plant cover was observed in areas with completely destroyed vegetation. During the period of study, the total coverage (including that of mosses and annual plants) in differe nt sites reached 12.6-90.4%, depending on degree of disturbance and th e local conditions determining the peculiarities of species compositio n and the stability of reestablishment of the vegetation.
