The article presents the features of forest litters of spruce, pine and aspen forests in the middle taiga subzone of the European north-east of Russia. Litter studies were carried out on the territory of the Lyalsky nature reserve (62 о15’N,50о40’E). The thickness, density, mass, fractional composition and carbon reserves in litter in different forest types were determined. The study showed an increase in humidity and litter reserves during the transition from non-swampy to swampy forest types, as well as high variability in the structure and properties of litter depending on the parcellation of forest biogeocenoses. In blueberry spruce forests the litter reserve in green moss parcels is about 49±17 t/ha, in sphagnum parcels is about 77.0±1.7 t/ha. In green moss pine forests the litter reserve in green moss parcels is 54±17 t/ha, and in microdepressions it reaches 67±15 (long-moss parcels) – 101±19 (sphagnum parcels) t/ha. In blueberry-sphagnum pine forests the litter reserve range from 90±16 to 150±25 t/ha. In aspen blueberry forests the above parameter is about 60±16 t/ha, increasing in long-moss plots to 71±27 t/ha. Carbon reserves in spruce forests are about 18 tC/ha, in green moss pine forests – 26 tC/ha, in sphagnum pine forests – 63 tC/ha, in aspen forests – 24 tC/ha. The litter parameters in the middle taiga of the Komi Republic are significantly affected by soil moisture. The relationship between litter stocks and their field moisture is described by the equation: y=5.3588ln(x)–20.56 (R 2=0.7537), where x is field humidity in the middle of the growing season, %, and y is litter stock, kg/m2.
