Abstract
The research relevance of the complex, multi-stage process of natural regeneration of forest communities, as well as interactions and transformations, is determined by the rapidly growing challenges posed by climate change, deforestation and biodiversity loss. The study aims to assess the state and to identify the ecological and coenotic specificity of natural seed regeneration of the leading forest-forming species of the Left-Bank Polissya of Ukraine. The study was carried out using a set of methods, primarily geobotanical, population and mathematical and statistical. The process of natural recovery was studied in communities that are typical for the region and belong to 42 syntaxa in the rank of associations and 24 syntaxa in the rank of association groups. The study revealed the specifics of such forest-forming species as Pinus sylvestris L., Quercus robur L., Acer platanoides L., Betula pendula Roth., Populus tremula L., and Tilia cordata Mill. The study established that the representation of the undergrowth of the main forest-forming species in the forest plant communities of the Left-Bank Polissya of Ukraine varies quite significantly. The study described the determinants of the species composition of restoration, including the peculiarities of seed (fruit) dispersion and the adaptive potential of plants. The study determined that the condition of the understory and its population density are determined by the level of soil moisture (the highest values of understory density in most species were recorded in forests with soils moistened at the level of fresh and wet hygro-tops), and this process may intensify against the background of climate change. The results of the study can be used to develop effective strategies for forest management, biodiversity conservation and sustainable forest management in the Left Bank Polissia region, which will help improve the environmental situation and create favourable conditions for the restoration of forest ecosystems
