“…Now, the Rublevaya River has not been established either in fact or according to satellite images. According to [Kharlamova, 2019], the trends of annual precipitation and moisture coefficients are negative for almost the entire territory of the forest-steppe and steppe regions of Kulunda in the Altai Territory during the almost 50-year period of 1966-2012. It could lead to the drying up of the river and the disappearance of an additional and significant source of Mg in the lakes of the Tanatar group because the composition of groundwater (spring waters) does not contain Mg (Table 3).…”

The lakes of the Kulunda plain have long attracted the attention of researchers. A detailed 10 geochemical testing of a chain of four small soda lakes of the Tanatar group allowed answering a 11 number of questions. We used a complex of modern methods of mineralogy and geochemistry to 12 update and add new data on the main phases of bottom sediments. The studied lakes have a pH ≥ 8 13 and a TDS of 2.1–41.5 g/L and a soda water composition. It has been established that over the 14 past ∼ 100 years there has been no change in the mineral composition of bottom sediments. The 15 main phases of the bottom sediments consist of intermediate and high – Mg calcite and Ca-excess 16 dolomite. Magnesite is presented only as a small impurity. The formation and accumulation of these 17 minerals occur throughout the core of bottom sediments. According to received data, a change in the 18 hydrological regime of the catchment area was established. The feeding regime of the lakes has been 19 changed because of the drying up of the Rublevaya River.

“…This requires research and monitoring of the main environmental factors affecting the state of the forest biotopes over the extensive, yet discontinuously wooded eastern parklands extending northwards into the Siberian mixed taiga belt by up to 350-400 km. As the process of deforestation and the mean annual air temperature (MAAT) rise over the territory intensifies [31], new problems of sustainability and biodiversity conservation of pine forests arise. Complex studies of the regularities of the vegetation dynamics, the identification of its anthropogenic degradation and the planning of measures for rational use and protection are needed.…”

The ribbon-like pine forests of North Kazakhstan represent the principal territorial intrazonal and azonal biotopes. Integrated bio-geographic studies of the pine forests’ status were performed in the Beskaragai and Chaldai Nature Reserves in the Pri-Irtysh River basin within, at present, the climate–change most susceptible transitional parkland-steppe zone of Central Asia, adjoining the West Siberian Lowland. The investigations followed the regional topographic gradient with a series of mapped sites characterizing the spatial relief patterns of the pristine forest distribution and the associated phytocenoses. The results revealed marked natural arboreal cover restoration differences between the geographically close upland and lowland forest ecosystems. The regional tree growth dynamics show the varying intensity of the pine seedlings’ succession, the tree stands’ biomass productivity and the environmental stability, weakened by the extreme continentality and progressing aridification along with adverse anthropogenic ecological impacts. The specific geomorphic, soil and hydrological conditions are the principal determining factors. The more vital plain and lowland pine forests host the floristically richer fescue-dominated communities compared to the more fragile and precipitation-poorer upland pine settings. The latter forest ecosystems display a higher vulnerability to the current climate change, generating tree drying, forest fires, and to modern human activities such as logging, herding and recreation. The research conclusions provide new insights on the natural ribbon-like pine forests’ sustainability and adaptation to the ongoing continental warming triggering fundamental environmental transformations in Central Asia’s parklands.

The Kulunda Steppe is an example of soil degradation resulting from the intensive agricultural land use in the South Siberia. In this region, water is a limiting factor for crop production. Soil cultivation affects the soil’s physical properties, thus its water retention capacity. The study presents and discusses the results of measurements of the volume and availability of soil moisture at depths of 30cm, 60cm, and 120cm of loamy, low humus southern chernozems in the south of Western Siberia in the dry Kulunda Steppe during the 2013 and 2016 vegetation periods. We revealed some advantages of soil moisture conservation in the No-Tillage [NT] system compared with the system of deep tillage [DT]. At depths of up to 30 cm, there was a lower volume moisture level. Nevertheless, at depths of 60 cm, there was a higher moisture level in the NT system that could be considered a potential stock for individual crops during drought. Further measurements are needed to identify additional features of the NT soil conservation system.
