Assessment of the state of entomofauna biodiversity on the sanitary protection zone of the poultry farm Kyivska

Abstract

Biodiversity ensures the functioning of ecosystems that provides oxygen, clean air and water, plant pollination, pest control, wastewater treatment and many ecosystem services. Recreational resources rely on our unique biodiversity, such as bird watching, hiking, camping, fishing etc. But it is known that anthropogenic load leads to degradation or destruction of natural landscapes. One of the manifestations of degradation is the fragmentation and division of solid forests or steppes into separate territories. As a result, they are transformed into small islands of nature surrounded by arable land, settlements, roads and railways. The leading ecologists think that a significant influence on the level of biodiversity has been identified (According to National report on the state of the environment in Ukraine in 2020). It was a result of anthropogenic pressure on the environment. Therefore, determining the level of entomofauna biodiversity in different stations is relevant. During the research, the condition of entomofauna on the natural, semi- natural stations and sanitary protection zone (SPZ) of the Poultry Farm Kyivska was assessed. As a result of analytical and faunal studies, constant-dominant orders were 2 revealed in research areas: Coleoptera, Lepidoptera and Diptera. These orders include more than 80% of species and others only about 20% of insect species. The low number of species of entomofauna of dendrobionts is established due to excessive anthropogenic load and the depleted species diversity of trees and shrubs. Preservation of the ecological stability of landscapes by reproduction and maintenance of biodiversity requires the additional creation of protective forest plantations with high species richness of plants.
