Reforestation on the burned areas of Southwestern Yakutia (for example Olyekminsky district)

Results of a research of post-fire communities of the Olekminsky district of the Sakha (Yakutia) Republic are presented in article. The Pacific Ocean - Eastern Siberia oil pipeline passes through the territory of the Olekminsky district, and research has been carried out on the burned area as part of a complex expedition. In terms of forestry, the study area is sufficiently studied, from the 1950s to the 1980s of the last century, systematic stationary studies of forests and mountain areas of South-Western Yakutia were carried out. But after the 1980th years due to the inaccessibility of the area, studies were not conducted. Researches are conducted in the route way on the site 200 km long on the highway 1594-2017 km. The study revealed a general picture of the current state of reforestation of burned in the forests of South-Western Yakutia. All set of descriptions was divided into stages of post-fire succession accepted for middle taiga Yakutia. The analysis of the constancy of plant species by stages of succession: initial, shrub, birch, late. An analysis of vegetation restoration by tiers (forest stand, shrub, grass-shrub, and moss-lichen) was carried out. It is revealed that each stage of a post-fire succession is characterized by existence in composition and structure of a vegetable cover of particular communities of plants. They gradually are replaced by species of plants, more characteristic of that forest vegetation situation, with particular life cycles and ecology. Reforestation on the burned areas of the Olekminsky district occurs similarly according to the scheme adopted for larch forests of the middle-taiga subzone.
