THE STRUCTURE DYNAMICS OF POST-PYROGENIC COWBERRY PINE STANDS OF THE NORTHERN CIS-URAL (KOMI REPUBLIC)

Observations results of the development of cowberry pine stands on Pechoro-Ilychsky Reserve territory using the method of permanent sample plots are presented. It was established that pine stands, despite the active replenishment of their species composition with young coniferous trees, have a relatively stable supply of stem wood. It is noted that with a prolonged absence of fires, an active replenishment of the forest stand with new generations of Pinus sylvestris, Picea obovata and Pinus sibirica trees of different ages. It revealed that grassroots weak fires contribute jump regeneration of Picea obovata and Pinus sibirica that are gradually introduced into the pine stands.
