| This paper is a summary of the structure study results obtained for a fir forest with some admixture of spruce and birch trees and a dense bamboo undergrowth, in the south of Sakhalin Island; this forest has grown after a fire that was there about hundred years ago. The characteristics of individual fir, spruce, birch and hornbeam trees were examined in terms of their trunk thicknesses, forest stratification and area distribution over the constant sample plot. As it is established, the Kuril bamboo sinusium strongly suppresses all plant species and prevents arboreal species restocking in the forest community. Only Siberian fir and spruce can compete it. The forest stand is distributed quite irregularly over the study area and is of different ages. According to the conducted study results, the development of forest community begins with individual fir trees, and then the other trees begin to grow around them. Later on, the tree groups are forming featured by a suppressed bamboo sinusium and alternating with bamboo-dominated glades. As the tree groups develop, the tree crowns meet thus causing the bamboo undergrowth to eliminate under the crown cover of dark coniferous forest. |
