“…rocky grasslands), occupy 47.5 % of the steppe belt and nearly 50 % of forest-steppe belt of Khakassia (Kuminova et al 1976). Today grazing and mowing are the main land-use types within the remaining steppe areas (Kandalova and Lysanova 2010). There is no agricultural land use within the ''Khakassky'' nature reserve (2680 km 2 ), in which seven of its nine subunits are located in the steppe and forest steppe zones (273 km 2 ).…”

The drivers of plant richness at fine spatial scales in steppe ecosystems are still not sufficiently understood. Our main research questions were: (i) How rich in plant species are the natural steppes of Southern Siberia compared to natural and semi-natural grasslands in other regions of the Palaearctic? (ii) What are the main environmental drivers of the diversity patterns in these steppes? (iii) What are the diversity–environment relationships and do they vary between spatial scales and among different taxonomic groups? We sampled the steppe vegetation (vascular plants, bryophytes and lichens) in Khakassia (Russia) with 39 nested-plot series (0.0001–100-m2 plot size) and 54 additional 10-m2 quadrats across the regional range of steppe types and measured various environmental variables. We measured β-diversity using z-values of power-law species–area relationships. GLM analyses were performed to assess the importance of environmental variables as predictors of species richness and z-value. Khakassian steppes showed both high α- and β-diversity. We found significant scale dependence for the z-values, which had their highest values at small spatial scales and then decreased exponentially. Total species richness was controlled predominantly by heat load index, mean annual precipitation, humus content and soil skeleton content. The positive role of soil pH was evident only for vascular plant species richness. Similar to other studies, we found that the importance of environmental factors strongly differed among taxonomic groups and across spatial scales, thus highlighting the need to study more than one taxon and more than one plot size to get a reliable picture

“…It should be noted that since carbon isotope ratios in the bone and dental collagen of the first-order consumers are enriched by 5‰ compared to the producers, the δ 13 C of the steppe vegetation is expected to be between -28‰ and -25‰. It is these δ 13 С values (from -27.6 to -25.4‰) that are observed in the vegetation of the steppes of Mongolia and Transbaikalia (Dambaev et al 2016) (Table 2).…”

“…H. Davie et al studied the isotopic composition of several mammal and plant species from the Ikh Nart Natyre Reserve (Davie et al 2014). V. Dambaev et al studied the carbon isotopic composition of vegetation and soils of steppe pastures in Mongolia and Western Transbaikalia (Dambaev et al 2016.). They also showed that against the backdrop of increasing degradation of pasture ecosystems, the main reason for which is the constant increase in the number of livestock, there is competition between wild and domestic animals for pasture niches.…”

The Mongolian–Transbaikalian region of the Central Asia is known for its wide range of intracontinental ecosystems from desert through steppe to taiga forest and mountain tundra. Data on the isotopic composition of carbon and nitrogen in the bone and dental tissues of herbivorous animals inhabiting the desert, steppe, and forest–steppe landscapes of Outer Mongolia and Western Transbaikalia are presented. The maximum values of the carbon isotope ratio are observed in animals from the desert (Gobi Desert) and the semi-desert landscapes, median (mean) δ13C is -17.9‰. The minimum values of δ13C were obtained by herbivorous animals of the forest-steppe and the forest landscapes (Transbaikalia), which median δ13C is -23‰. The fauna of the steppes (median δ13C is -21.7‰) has intermediate values of the carbon isotopic composition. According to the isotope composition of nitrogen, the isotope-geochemical isolation of ecosystems is less pronounced.

“…Pasture agrolandscapes are formed for grazing or haymaking. Their characteristic and most important feature is the constant vegetation cover and specific phytocenotic parameters that are regulated by humans [16,[25][26][27]. Spatial structure optimization of pasture agrolandscapes implies a certain ratio of grassy, forest-protected, and other geocomplexes, which are correctly placed from the viewpoint of landscape ecology [28].…”

“…The coexistence of multiple land uses, such as crop cultivation, forestry, and wildlife habitat, can result in conflicts among stakeholders and lead to the degradation of the ecosystem [15]. To address this issue, a holistic and integrated approach is required that considers the various ecological, economic, and social factors involved in the management of pasture agrolandscapes [16]. This approach should incorporate sustainable land use practices that balance the different land uses, promote biodiversity, and enhance the resilience of the ecosystem to environmental stresses [17].…”

Towards Sustainable Pasture Agrolandscapes: A Landscape-Ecological-Indicative Approach to Environmental Audits and Impact Assessments

Reliable environmental audits and impact assessments are essential to achieve effective pasture utilization and ensure the production of high-quality livestock products. This study aims to develop an environmental audit and impact assessment method for pasture agrolandscapes to promote sustainable livestock practices, using Central Kazakhstan as a case study. To provide a strong foundation for this research, the study utilized representations of pasture agrolandscapes, landscape-ecological and landscape-indicative approaches, and interactions between environmental audits and impact assessments in Kazakhstan. The authors acknowledge that their understanding of the environmental audit and impact assessment for pasture agrolandscapes is a complex method that requires specific knowledge and information about the landscape environment from users. They note that solving the challenges of national food security and environmentally safe territorial development can be achieved through the development of a private method that uses landscape environment status indicators. Methods similar to this enable the study of geocomplexes and their crucial characteristics, leading to a unique system of reliable indicators for environmental issues. This approach facilitates the creation of a scientifically based plan for optimal regional land use and land management systems regarding pasture agrolandscapes.
