Vegetation and fauna features in the zone of influence of the solid waste landfill «Preobrazhenka» (Samara Region)

Abstract

The anthropogenic factor has a significant impact on the natural-territorial complexes of the Samara Region. Solid waste landfills have a significant impact on the soil and vegetation cover and the animal population, which is due to the alienation of territories as well as the negative impact of leachate and emitted gases into the environment. The purpose of our research is to study the vegetation cover and fauna on the territory of the zone of influence of solid waste landfill Preobrazhenka (Volzhsky District, Samara Region), including the area near the filtrate storage ponds. In the course of the work, geobotanical, floristic, zoological and ecological methods were used. 15 stationary areas were established in the study area around the storage ponds. The authors revealed the composition of phytocenoses, including the associations Galatella villossa Stipa lessingiana, Galatella villossa Stipa lessingiana Onosma simplicissima, Elytrigia repens + forbs, Elytrigia repens Phragmites australis forbs, Elytrigia repens Phragmites australis, Poa angustifolia + Galatella villossa, Quercus robur + Acer platanoides Aegopodium podagraria, Populus tremula Urtica dioica, Poa angustifolia + Galatella villossa, Salix triandra Salix fragilis forbs, Cyclachaena xanthiifolia Polygonum aviculare. The total flora of the territory includes 140 species of vascular plants. The authors have found 36 species of animals, 16 are invertebrates and 20 are vertebrates among them. The general state of biogeocenoses in the area of storage ponds is considered to be unsatisfactory, downstream of the ravine-gully system and on its slopes satisfactory. It is necessary to carry out reclamation of the object.
