Ecological structure of burnt-wood flora and stages of their overgrowth in plain pine forests of Altai krai

The ecological structure of burnt-wood flora largely depends on natural and climatic conditions and geographical location. Secondary postfire successions in plain pine forests pass rather quickly, and burnt woods are at the stage of the development of communities of patient plants in 10 years. Pyrophyte plants acquire great significance in the development of vegetation of burnt wood. The development of zonal types of vegetation does not occur in 10 years. A decrease in interfire periods results in the fact that plant communities are under the constant influence of the pyrogenic factor in plain pine forests.
