Stocks of phytodetrite and its biogenic elements in larch forests in small watershead basin of Central Evenkia
The article notes the main sources of phytodetritus in undisturbed cryolithic larch forests of Central Evenkia. The features of the distribution of phytodetritus stocks and its individual components depending on the age of forest stands (young, mature and overmature) and forest types are considered....

The article notes the main sources of phytodetritus in undisturbed cryolithic larch forests of Central Evenkia. The features of the distribution of phytodetritus stocks and its individual components depending on the age of forest stands (young, mature and overmature) and forest types are considered. All these stands were formed on the territory of a small drainage basin in Central Evenkia after intensive ground fires in the early and last decades of the 20th century. An uneven distribution of litter stocks was revealed both in age groups and forest types. Significant annual fluctuations in litter stocks over 7-year observation period were also noted. The composition of the litter is dominated by needles – 84.8–93.2% of the total mass, while the branches and bark of larch (Larix Mill.) and birch (Betula L.) leaves account for only 3.0–3.2, 4.5–2.6, and 7.7–< 1 %, respectively.
