Abstract

Ecological structure of flora burnt depends on climatic conditions and geographic location. The secondary post-fire succession in lowland pine forests occurs rather rapidly, and after ten years the burns are at the stage of the formation of communities of patient plants. Pyrophyte plants become important in the formation of vegetation in burns. Formation of zonal vegetation types does not occur in ten years. A reduction of periods between fires leads to the fact that plant communities in flat pine forests are under constant influence of the pyrogenic factor.
