Urban flora of astana (Kazakhstan): A technology for creating a comfortable ecosystem

Abstract

This paper describes the results of studying the state of tree plantations in the harsh climatic conditions of Astana. In this paper, the authors describe the assessment of the living state of the main tree varieties, their resistance to pests and diseases as elements of the emerging urban flora. The methods generally adopted in botany were used for assessing the sustainability of tree species and their living state. Total estimation of the living state of trees of each species in the green plantations was performed by 10 – 25 model trees. At seven objects (SP1 – SP7) of the research, widely spread tree crops (Populus balsamifera L., Populus pyramidalis Salisb., Populus alba L. and Populus bolleana Lauche, Picea pungens Engelm., Pinus sylvestris L., Ulmus parvifolia Jacq. and Ulmus glabra “Pendula”), Betula pendula Roth., Salix fragilis L.) show various degrees of resistance to ecotopic conditions, and have various positions in amenity planting of the city and the urban flora formed.
