Abstract
Changes of plant communities in sand and sabulous pits during overgrowing for different time intervals in the northern taiga of West Siberia were studied during the recent 13 years. It was demonstrated that at the first stage of overgrowing the species composition of the communities depends on the physical properties of the ground. Either grass or woody species dominate at this stage. Later on, the change of phytocoenoses leads to the development of the forest community of the zonal or derived type. The time of the appearance of the forest phytocoenosis depends on chance factors.
