Poisonous and harmful plants of pastures in the Kyzylkum desert (Uzbekistan)

Abstract

The paper studied poisonous and harmful plants that were distributed in Kyzylkum desert condition (Uzbekistan). The research was conducted over the years 2012-2024. The forage flora of Kyzylkum consists of 908 species of vascular plants belonging to 345 genera and 68 families. During the research, 34 families, 73 poisonous plants belonging to 55 genus and 6 families, 39 harmful plants belonging to 13 genera were identified. The vast majority of poisonous and harmful plants are xerophytes. The analysis of poisonous plants of the studied territory in relation to soil moisture showed that the vast majority of them belong to xerophytes, which confirms the arid nature of the pastoral flora of Kyzylkum. The dominant positions of annual plants in the forage flora of the study area have been revealed, which are an alarming indicator of increasing anthropogenic pressure on pasture vegetation. The colossal role of haze and compound flowers in the pasture vegetation of Central Asia has been established and the expediency of separating them into separate groups according to economic relations has been proved.
