К ФЛОРЕ ПАМЯТНИКА ПРИРОДЫ «ЗЕЛЕНИНСКИЙ ЛЕС» (БРЯНСКАЯ ОБЛАСТЬ)

Abstract

Based on the data of floristic and geobotanical studies carried out by the authors in 2014–2020, an analysis of herbarium collections (BRSU) and some literary sources on the flora and vegetation of the region, a List of vascular plants of the nature monument «Zeleninsky les» (Bryansk Region, Russia) composed. The List includes 458 species, 14 of which are included in the regional Red Data Book. It reflects the state of the flora at the mo-ment and will be in demand for further monitoring of the biodiversity of the natural monument. As the research has shown, the territory of the «Zeleninsky les» is of great importance for the preservation of floristic diversity and regionally rare species of vascular plants. However, the state of the vegetation cover of this protected area raises serious concerns. Currently, there is a rapid change in the appearance of plant communities due to xero-phytization of the valley of the Sev River and its tributaries. The introduction and dominance of dangerous alien plants Acer negundo and Heracleum sosnowskyi in natural communities can lead to a reduction in the floristic diversity of protected area.
