Mountain forests of the Northern Tien Shan are distinguished by high floristic diversity and a large number of plant communities. Among the latter there are several unique relict plant communities dominated by Picea, Malus, Prunus, and Celtis spp, as well as tugai forests. The most species-rich are forests dominated by Picea schrenkiana Fisch. & C.A. Mey. (450-500 species), Malus sieversi (Ledeb.) M. Roem. (400 species), and Armeniaca vulgaris Lam. (about 250 species). The least species-rich are tugai forests with Hippophae rhamnoides L. (140 species) and hackberry forests dominated by Celtis caucasica Willd. (119 species). In these forests, there are 24 Red Book species, including Hepatica falconeri (Thoms.) Steward, Epipactis palustris (L.) Crantz, Tulipa tarda Stapf, and Gymnospermium altaicum (Pall.) Spach., which are the objects of special research. The article presents the results of the study of natural populations of the last three species, in particular, the numbers and density, ...
