Abstract

The manysided research and subsequent analysis of growing stock factors with Pinus rigida Mill. и P. banksiana Lamb on Ukrainian Polissia were performed to highlight the features of successful adaptive process, as much attention should be paid exactly the planting exotic species that have passed the primary stage of acclimatization and are restored to the nature themselves. At these facilities were studied the structure and composition of the soil and growing, and then a phytosociological description was made on the basis of floristic classification of vegetation using the method by J. Braun-Blanquet. In the first explored area a plantation was formed fairly stable and adaptive to their environment. Natural association here was the association of wet millet-grasses Molinio (caeruleae)-Pinetum. At the current stage forest association Leucobryo-Pinetum is identified. On the second explored area artificial stands with exotic species of pine which had been developed in the past and also were found in a new ecological niche here. At the time of the survey it is classified as phytocenosis association Querco roboris-Pinetum (Syn. Pino-Quercetum). Exotic species of pine have been successfully adapted in conditions of Ukrainian Polissia and show high amount of growth. In addition, forest phytocenosis has accepted this plantation and at this stage there have been resumed characteristic species of phytocenosis and have been developed a natural restocking of forest as well as a characteristic mycobiota.
