Aims: Landscapes of Middle Asia are exposed to human influence due to long-lasting pastoral tradition, and now are largely dominated by non-forest vegetation. Graminoids perform key ecosystem functions, and constitute an important feed source for livestock. We studied the distribution patterns of graminoids cover under climatic and grazing pressure gradients in different open vegetation types. Study area: Tajikistan, Kyrgyzstan. Methods: 1,525 vegetation plots representing five open vegetation types (mires, salt marshes, tall-forb communities, pseudosteppes and steppes) were extracted from the Vegetation of Middle Asia Database. We assessed the relative cover of graminoid species in each vegetation type. The importance of mean annual temperature, sum of annual precipitation, aridity and livestock density as drivers of relative cover of graminoids contribution patterns in the five vegetation types were explored with use of polynomial functions and commonality analysis. Results: Open ecosystems of Middle Asia are characterized by different graminoid contributions. The highest relative cover of graminoids was found for steppes, pseudosteppes and mires. Comparison of model fits for relationship between the graminoids cover, climatic parameters and livestock pressure indicated advantage of polynomial models. The best-fitting models for pseudosteppes were for mean annual temperature, Aridity Index and livestock density, for steppes mean annual temperature and Aridity Index, and for salt marshes mean annual temperature. For mires and tall-forb communities, the models showed a poor fit or no effect of the variables studied. Conclusions: Our study shows that climate and livestock pressure have an impact on the contribution of graminoids in open vegetation types, but a general pattern is difficult to describe. Ongoing climate change may influence the share of graminoids in salt marshes, steppes and pseudosteppes. Grazing (with a common effect of climatic factors) is the most important factor influencing graminoids contribution on pseudosteppes, confirming the secondary origin of this vegetation type. Taxonomic reference: The nomenclature of the vascular plants follows Plants of the World Online (POWO 2022) and problematic taxonomic issues were based on The World Flora Online (WFO 2022). Nomenclature of Stipa spp. follows Nobis et al. (2020).

“…The vegetation cover of the pastures in the arid regions of the southwestern region of Uzbekistan has a complex structure, which is due to the initial stagnation of the micro-and meso-relief landscape, soil denudation, salt accumulation, and the increase of moisture in soil profiles. Most of the species occurring in these regions belong to the Chenopodiaceae, Asteraceae, Poaceae, Fabaceae and Brassicaceae families, relatively low to the Polygonaceae, Plumbaginaceae, Zygophyllaceae, Cyperaceae families, and very few species belong to the Eleagnaceae, Plantagainaceae and Frankeniaceae families (Toderich et al 2013). Researchers have recorded more than 600 species of plants in these regions including Artemisia diffusa, Ceratoides ewersmanniana, Kochia prostrata (Khaydarov et al 2020, Valiyev et al 2023, Cousinia resinosa (Islamov et al 2020), Halocnemum strobilaceum (Alikulov et al 2023), Halostachys belangeriana (Alikulov et al 2022).…”

Abstract. Bazarov B, Rajamuradov Z, Safin M, Rajabov A, Khayitov D, Kuziev M, Aminjonov S, Ismayilova M, Kudratov J, Khujabekov M, Khaydarov D. 2023. The productivity, chemical composition and nutritional value of pastures dominated by Artemisia diffusa and Cousinia resinosa in arid lands of southwestern Uzbekistan. Biodiversitas 24: 3916-3923. In recent years, extensive degradation of pastures has been observed all over the world as a result of drastic changes in climate and the increase of anthropogenic factors. As a result, the biological diversity of plant communities in pastures decreases, and specific changes occur in dry mass productivity, nutritional value, and other indicators of plant biomass. Therefore, studies aimed at assessing the condition of the vegetation in pastures are important. This research is one of the first studies of this type aimed at determining the biomass yield of pastures dominated by Artemisia diffusa Krasch. ex Poljako and Cousinia resinosa Juz. at varying elevations in arid areas of the southwestern regions of Uzbekistan, analyzing the chemical composition and nutritional value contained in the plants and evaluating the yield and quality of milk of goats fed with such plants. The results showed that dry mass yield, chemical composition, amount of substance, and nutritional value of the biomass produced by the plants in the pastures were directly influenced by the type of plants that make up the pasture, the elevation of the pastures, and climate factors (i.e., season). Our analysis also showed that the resiproductivity, chemical composition, and nutritional parameters were the highest in the mountain pastures compared to those in the hill and desert pastures. Goats fed by grazing in the pastures produced a higher yield and quality of milk compared to goats fed with conventional rations. The findings of this study explain the diversity of the productivity, chemical composition, nutritional value, and potential of the biomass produced by plants in pastures with dominant species A. diffusa and C. resinosa in increasing goat milk production in arid regions.
