Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

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, ...
