Abstract

The present study is based on monitoring the state of the natural vegetation cover in the western part of the Kyrgyz Alatau in order to identify major changes in vegetation from the perspective of natural regionalization, and to develop classification schemes for analyzing plant communities. Studying the composition and structure of vegetation in specific regions allows for the identification of floristic connections among various phyto-geographical areas. In recent years, the flora of the western part of the Kyrgyz Alatau, within the territory of Kazakhstan, has been insufficiently studied. Despite occasional visits by botanists, the flora of the western Kyrgyz Alatau remains insufficiently researched. The species composition, ecology, and distribution of individual species within the region are not fully identified. Field research on the flora species of the western Kyrgyz Alatau was conducted from May to September in accordance with the schedule of expedition and fieldwork, and was also based on herbarium materials collected by the author and colleagues. The coordinates of the plant collection sites in the western part of the Kyrgyz Alatau were determined using the GPS navigation method. The primary research method was the route-survey method. Nine expedition routes covering the western part of the Kyrgyz Alatau were developed. Due to the long-standing difficulties in studying the flora composition of these regions, the conducted research is aimed at inventorying the floristic diversity of the western part of the Kyrgyz range. A floral study of the vegetation of the Kyrgyz Alatau range was conducted, and based on the present study and existing literature 86 families, 501 genera and 1,471 species were identified. In the Zhambyl region, the most vulnerable plant communities—steppe ecosystems—are the result of the combined impact of human and natural factors. Floristic research forms the foundation for any phyto-geographical analysis. The materials presented in this article are of practical importance for conducting scientific research in regions where issues related to changes in the natural environment and climate are especially relevant. Solving these issues is important not only for Kazakhstan, but also for the global community
