Ayubova E. Importance of forest belts for the formation and support of bird groups in the North-Western Priazovye

The dissertation considers the influence of artificial forest belts on the formation, maintenance and conservation of birds in the North-Western Priazovye. The population of birds, nests, species composition of trees and shrubs in the control, as well as in other forest belts during the spring-summer period was recorded. As a result of monitoring, 62 species of reliably or reliably nesting birds were identified. The analysis of the distribution of bird species in the forest belts of the North-Western Priazovye by taxonomic and zoogeographical characteristics has been carried out. The chorological structure of the population of birds of forest belts is analyzed. They were found at the nesting site: in tree canopies, in hollows, in bushes, in a grass layer or on the ground. Observations and analysis of data on the trophic structure of birds of the studied forest belts were carried out: entomophages, phytophages, myophages, pantophages and ichthyophages. The ecological conditions that have developed in the forest belts, their dynamics over time, the influence of each of the factors on the grouping of birds of the experimental forest belts are analyzed. The influence of typological characteristics of forest belts: age, construction, composition of tree and shrub species, light structure on the formation of species and quantitative composition of groups of birds is determined. The consortium relations of birds with trees and bushes of forest belts have been studied. As a result, topical, factory, trophic connections are revealed. Ornithoconsortia with edificators of forest belts were investigated. Studies of sedentary activity of birds (ornithochoria) were carried out and it was found that in the process of versatile activity birds create foci of tree and shrub species under the pylons, among which the dominant ones are: hawthorn and dog rose. The influence of pyrogenic factor on the grouping of birds in the forest belts was studied and the dynamics of pyrogenic succession development was studied. It was found out that the artificial forest belts of the North-Western Priazovye are of nature protection significance.
