Kazakhstan's rich cultural heritage includes traditional knowledge of plant-based remedies for animal health. This study aimed to document the ethnobotanical knowledge of medicinal plants used to treat equine digestive disorders in Kazakhstan, focusing on identifying culturally significant plants, their modes of preparation, and administration. Ethnobotanical data were collected through semi-structured interviews and participatory observation with 70 informants, including horse breeders, traditional healers, and community elders across three regions of Kazakhstan. Plant specimens were collected, identified, and deposited in a national herbarium. Data were analyzed using descriptive statistics and ethnobotanical indices, including Use Value (UV), Informant Consensus Factor (ICF), and Fidelity Level (FL). The survey documented 40 plant species from 24 families used in treating equine digestive disorders. Glycyrrhiza uralensis (UV = 0.86), Ferula assa-foetida (UV = 0.79), and Artemisia absinthium (UV = 0.74) were among the most frequently cited plants. Roots and aerial parts were commonly used, often prepared as decoctions (37.5%) or infusions (30.0%). High informant consensus was observed for treatments of gastric ulcers (ICF = 0.939) and diarrhea (ICF = 0.929). Artemisia absinthium showed the highest fidelity (FL = 98.08%) for treating intestinal parasites. The majority of informants (54.3%) reported acquiring their ethnobotanical knowledge through family traditions, and 82.9% practiced selective harvesting for conservation. This study reveals the rich ethnobotanical knowledge of the Kazakh community regarding equine digestive health. The high consensus among informants suggests a well-established traditional knowledge system.

Environmental pollution by industrial waste, including brown coal mining, is one of the environmental problems of many countries. To improve the ecological situation in the region, it is necessary to recultivate soils contaminated with brown coal waste. The goal of the study was to study the possibility of biorecultivation of soils polluted with brown coal waste from the Lenger deposit located in the south of Kazakhstan. It was found that the inorganic part of the brown coal waste is represented by minerals: Quartz SiO2, Gypsum CaSO4×2H2O, Kaolinite Al2Si2O5(OH)4, Cronstedtite Fe3((Si0.74 Fe0.26)2O5)(OH)4, Margarite CaAl2(Si2Al2)O10(OH)2, Muscovite H2KAl3(SiO4)3, Calcite CaCO3, Laumontite CaAl2Si4O12(H2O)2, Lead Aluminium Sulfate Hydroxide Pb0.5Al3(SO4)2(OH)6, with quartz content in samples in the range of 61.5-92.9%. The organic part of the waste is 90.0% made up of humic acids and fulvic acids. It has been established that heterotrophic, cellulolytic microflora and micromycetes are represented by the genera Rhodococcus, Bacillus, Pseudomonas, Penicillium; Trichoderma, Dietzia, promising for biorecultivation purposes. The phytocenosis of coal waste dumps is composed of toxicotolerant ruderal plant species of the local flora: Centaurea scabiosa L., Centaurea iberica Trev., Cichorium intybus Linn., Cousinia cyrdariensis Kult., Achilleamille folium L., Thlaspiar vense L., Arctiumto mentosum Mill., Onopórduma cánthium L., Agropyron cristatum L., Phlum pratense L., Erytrigia repens L., Nevski/Agropyron repens L., Cynodon dactylon L., Capparis spinosa L., Polygonum aviculare L., Dodartia orientalis L., Althaea officinales L., Alhagipseud alhagi (Bieb.)Desv., Peganum harmala L. For biorecultivation of soils contaminated with brown coal waste, an algorithm of work has been developed, including the use of soil blocks with integrated seeds of toxicotolerant plants inoculated with microorganisms.
