Abstract: We examined specificity of fine root distribution and root detritus stock in permafrost soils under mossy-subshrub larch forests (Larix gmelinii (Rupr.)Rupr.) The sample plots were situated in northern taiga of Central Siberia and in mountain permafrost larch forests in the Lake Baikal Region. It was found that trees, sub-shrubs and grasses have different patterns of fine root distribution inside the 0-20 cm soil layer. Patterns of fine root distribution and plant detritus accumulation can be a result of different root growth strategies of tree and sub-shrub life forms.
