Characteristic of Forest Cover of Western Part of the Lensky Rayon of the Republic of Sakha (Yakutia)
Larix gmelinii and Larix sibirica dominate in the forest cover in the western part of the Lensky rayon. Vaccinium vitis-idaea larch forests are widely represented and form extensive forest areas. Pine forests are the second most important formation of coniferous forests in the study area. Pine forests (Pinus sylvestris) cover the upper part of the elevations. Pine forests with well-developed moss cover dominate. Spruce forests (Picea obovata) have a limited dispersal. The limited dispersal of spruce forests is due to the spruce greater demands for soil fertility, soil moisture, hydrothermal regime of permafrost soils. Birch forests (Betula platyphylla) are the part of successional range of reforestation climax types of larch and pine forests. Birch forests grow along the floodplains with overmoisturizing, on the recovering burned and cutting areas. The distribution of types and forest formations on the terrain corresponds the conditions of moisture availability. The alienation of forest areas for industrial facilities are the greatest danger to the forest cover.
