Abstract

Non-metric multidimensional scaling (NMDS) was used to analyze spatial changes in the structure of tugai vegetation in the Aral Sea region. The results indicate that although the tugai vegetation in Northwestern Kyzylkum is more extensive and better preserved than in other parts of the region, it is still affected by both anthropogenic and natural factors. The decrease in the abundance of dominant species is associated with changes in the hydrological regime, increased evaporation, and uncontrolled logging. Excessive deforestation of tugai forests for timber, firewood, and other purposes leads to a reduction in the area available for these dominant species.
