Dynamics of the number of hunting animals in the area of the alleged flooding of the Nizhneboguchanskaya HPP

The forecast of changes in the biodiversity of fauna in the zone of expected influence of regulated water bodies is based on the basis of monitoring of hunting resources. A list of the main game animals of the Boguchansky district of the Krasnoyarsk Territory has been compiled. Winter route surveys were carried out on the right and left banks of the Angara River in the zone of alleged flooding during the construction of the Nizhneboguchanskaya HPP. The number of commercial species and its dynamics for three years were revealed. Species-specific essays have been compiled that characterize the abundance of the animal in the study area with predictive changes in ranges and population density. Recommendations are given on measures to minimize the anthropogenic impact of the HPP construction

Diversity of the vegetation cover of the zone of potential influence of the Nizhneboguchanskaya HPP (Lower Angara region)

Active economic development of the Lower Angara zone requires the creation of a scientific basis for long-term monitoring of the state of natural ecosystems. The paper gives an assessment of the diversity of vegetation cover in the zone of potential influence of the Nizhneboguchanskaya HPP. An analysis of its typological structure on a landscape-ecological basis is given. The results of the DCA ordination and the interpretation of the leading axes of variation demonstrated the presence of four distinct groups of forest types that form ecological series according to the leading factors - the richness and hydrothermal regimes of soils. The dendrogram of forest types in the study area reflects the floristic integrity of the identified groups of forest types and the floristic relationships between them
