Structure Formation of Forest Tree Species Coenopopulations During Post-Fire Recovery of Northern Taiga Forest
The goal of this study was to compare the coenopopulation structure of two main stand-forming tree species of European northern taiga forest – Picea obovata Ledeb. and Pinus sylvestris L. at different stages of post-fire successions. Investigations were carried out in the Kola Peninsula (67°30ʹ–68°1...
