Dwarf pine (Pinus pumila) is a main species of underbrush in the larch and stone-birch forests of the southern part of Magadan region (Northern Okhotsk Sea Coast). Intensive renewal of dwarf pine on the cuttings over and burned-out forests is followed by development of its pronounced habitat-forming functions that allows to it to become со-aedificator of the major forest-forming species, or an aedificator of an ecosystem at the age of 70-80 years. The shaping peculiarities of Pinus pumila coenopopulations have been considered in different type's forests from juvenile stage to an overripe age, taking into account changes of the tree-stand habitat-forming functions. Characteristics of the explored phytocenoses are given. The shaping process of a cup-like and creeping ecobiomorphs of dwarf pine in the primary and derivative parcels of overmature stone-birch-forest are described. The biometric indexes of dwarf pine and their transformation for 20 years in dry and humid ecotops and information about pine-needles age in various growth conditions are adduced.
