Riparian forests in the valley area of Irtysh River Basin are capable providing a variety ecosystem services such as water conservation and biodiversity maintenance. Their health condition is an important reflection their ability to maintain stability structure perform functions. In this study, comprehensive survey was conducted observe typical distribution areas riparian six tributaries one main stream Basin. Twelve indicators were chosen from three categories vigor (i.e., productivity), organization species diversity complexity), resistance harmful factors disturbances) form evaluation system. Expert-based statistical weighting applied calculate scores prioritized grades seven rivers. Several criteria used further classify unhealthy level each river individually. The results study can be foundation for future orderly development area. show that (1) Kuyertes classified healthy, while Haba Berezek Rivers unhealthy.

Assessment of Plant Biodiversity and the Floristic Composition in the Black Irtysh River Valley (Kazakhstan)

Diversity, Journal Year: 2024, Volume and Issue: 16(10), P. 641 - 641

Published: Oct. 16, 2024

The Black Irtysh River, a major tributary of the Ob traverses diverse ecological zones, influencing distribution and composition its floodplain vegetation. This study focused on River valley, key segment basin, to assess current state plant communities. To compile expedition routes preliminary floristic list, critical revision more than 1000 herbarium sheets was carried out in collections Kazakhstan (Altai Botanical Garden Institute Botany Phytointroduction). During field season, biodiversity along entire coastline Irtysh. As result, 217 species higher vascular plants were identified (55% those previously found archives) from 139 genera 43 families. habitats two Red Book discovered: Tulipa patens uniflora. It that flora is similar Zaisan depression, families Poaceae, Asteraceae, Amaranthaceae, Caryophyllaceae, Rosaceae, Fabaceae are predominant. Geobotanical surveys revealed communities poor among survey points. Only western part river delta characterized by high rates projective cover reserves forage plants. main factors anthropogenic influence fires, livestock grazing, deforestation.
