Changes in the Biomass of Vegetation in the Aral Sea Region

Abstract

Long-term changes in the plant biomass of the dried bottom of the Aral Sea and the Karakalpak part of the Ustyurt plateau were determined. Despite the drying of the Aral Sea 50 years ago, primary and intermediate stages of vegetation haloseries dominated by annual and shrub halophyte fraction remains as the main directing force of succession. The emergence and increase in the area of "zero" or arid local territories after the 1990s is observed in the central, especially southern part of the Karakalpak Ustyurt. In contrast to the formation of vegetation on the drained bottom of the Aral Sea, long-term changes in the biomass of various natural-territorial complexes of Ustyurt are characterized by a negative correlation with a reduction in the area of mirrors over the past 30 years.

Assessment of the current state of rangelands in Karakalpak Ustyurt, Uzbekistan

“…Therefore, a conceptual approach to solving the problem of biodiversity should be based on the priority consideration of the ecosystem function of biodiversity. Numerous studies were conducted on the conservation of biodiversity in different ecosystems in Uzbekistan (Adilov et al 2021a;Rakhimova et al 2021aRakhimova et al , 2021bShomurodov et al 2021;Akhmedov et al 2021;Akramov et al 2021;Saribaeva et al 2022;Temirov and Rakhimova 2022;Sharipova et al 2022;Akhmedov et al 2022;Halimova and Rakhimova 2022;Rakhimova and Rakhimova 2022a, 2022b, 2022cRakhimova et al 2022;Saitjanova and Shomurodov 2022;Shomurodov et al 2022;Vaisova et al 2022;Abduraimov et al 2023aAbduraimov et al , 2023bRakhimova et al 2023aRakhimova et al , 2023bKhamraeva et al 2023).…”
