This article presents the results of a comprehensive assessment of the ecological status of populations of the rare endemic species Schmalhausenia nidulans native to the high-mountain regions of the Northern Tien Shan. The aim of the study was to investigate the current state of the species populations by analyzing their numbers, ontogenetic structure, morphometric parameters, and anatomical features. Two natural populations of the species were examined: the first population, located on the Uzynkara Ridge at an altitude of 3003 m above sea level, and the second population, growing on the Ile-Alatau Ridge at an altitude of 3260 m above sea level. During the field research, the population size, age structure, and morphological traits of individuals at the juvenile, immature, virginal, and generative stages of development were studied, and an anatomical analysis of the stem structure was also conducted.

The article examines the current status of populations of Phedimus hybridus (L.) 't Hart (also known as Sedum hybridum L. and Aizopsis hybrida (L.) Grulich) and Hylotelephium ewersii (Ledeb.) H. Ohba (formerly Sedum ewersii Ledeb.) in the Kok-Zhailau Gorge, part of the flora of the Ile Alatau. The study explores the biology of these species, including their population dynamics and life forms, as well as their ecological responses to specific ecological-cenotic conditions. P. hybridus is valued in traditional medicine for its diverse therapeutic properties, such as anti-inflammatory effects, stimulation of the nervous system, antidepressant and wound-healing actions, and inhibition of leukocytosis. In contrast, H. ewersii is commonly cultivated as an ornamental plant. The article also includes a taxonomic, ecological, and geographical analysis of the flora associated with the populations of P. hybridus and H. ewersii in the Kok-Zhailau Gorge.
