Abstract

The data of phytocenotic studies of saxaul forests of Northern Kyzylkum under certain forest growing conditions are presented. 10 plant communities have been described. The predominance of communities with the participation of Haloxylon aphyllum (Minkw.) Iljin (5 communities) and mixed saxaul communities from Haloxylon aphyllum and Haloxylon persicum Bunge ex Boiss was established. & Buhse (4 communities), a single white-saxaul community from Haloxylon persicum. Saxaul communities are rare with a small amount of saxaul undergrowth. The species developed normally, but did not reach their usual size, went through the entire cycle of their development ,and bore fruits. Taxonomic analysis of the flora showed the presence of 41 species from 31 genera and 15 families. The total projective coverage of all plants in the communities ranged from 30 to 100%. Groups of plant species by economic value are identified. The results of the study can be used to assess structural ecological and morphological changes in the natural and anthropogenic environmental conditions of other regions of Kazakhstan and other countries.
