Abstract
The present study is devoted to the assessment of the impact of Populus tremula conservation on the dynamics of woody vegetation in 15-year-old clearcuts in wood sorrel-spruce forests of the Vologda region. The objective is to examine autogenous succession and natural regeneration. The methodology involved the establishment of 60 sample plots on clear-cuts and in adjacent forests with varying aspen preservation strategies, including single trees, clumps, and no preservation. A comprehensive analysis of stand structure, the vital state of tree components and undergrowth characteristics was conducted. The findings illustrate the beneficial impact of aspen conservation on the acceleration of reforestation processes and the establishment of favourable conditions for the growth of shade-tolerant species, particularly Picea abies. The greatest efficacy in maintaining tree diversity and optimizing microclimatic conditions was observed in the conservation of aspen in clumps. A decline in the vitality of aspen and spruce was observed with increasing post-exploitation periods, while trees in clusters exhibited higher vitality indices compared to single specimens. The undergrowth analysis revealed the dominance of soft-leaved species in the early stages of succession, with a subsequent increase in the proportion of shade-tolerant species. The findings confirm the importance of retention silviculture for biodiversity conservation and restoration of forest ecosystems after clear-cutting.
