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

The genus Ajania Poljakov is a perennial herbaceous plant, usually with grayish shade, without shortened vegetative shoots, with erect or often ascending and branched, well-developed, densely oleate stems. Leaves are ordinary with dissected laminae covered with appressed bipinnate, sometimes with admixture of simple hairs. The purpose of this research work is to clarify the current state of the population of Ajania fastigiata occurring in the Trans-Ili Alatau. The objects of the study are phytocenoses with participation and dominance of the medicinal species Ajania fastigiata growing in Trans-Ili Alatau. As a result of the analysis of the described 3 large populations of the medicinal species Ajania fastigiata, the following conclusions were obtained. According to the analysis of floristic composition of communities with participation and dominance of the studied species, 104 associated species (23 families) were identified. Asteraceae - 15 species, Poaceae - 11, Fabaceae - 10, Ranunculaceae and Rosaceae - 9 each, Lamiaceae - 8, Apiaceae - 7, Boraginaceae and Caryophyllaceae - 6 each, Liliaceae - 5 species (possibly more), 18 species belong to different families. For Pop1 the tallest individuals, 120 cm in height, were recorded. Pop1 (cop2) and Pop3 (cop3) were the most abundant populations. According to the percentage of Pop1 juveniles was about 43%, Pop2 juveniles 44%, and Pop3 juveniles 55%. The age composition relative to the number of individuals showed that Pop1 and Pop3 are growing populations, while Pop2 is close to a regressive population caused by anthropogenic pressure.
