Abstract

The article is devoted to the complex study of the cenopopulations of the rare endemic species
Oxytropis almaatensis and to the cenopopulations assessment. As a result of the conducted studies, the
features of the ecological-cenotic confinement of the cenopopulations O.almaatensis were revealed. All
three populations of the studied species are located on the axes of the northern macroslope of the TransIli Alatau mountains and on stony-gravel deposits along rivers occupying by small areas ranging from
1200 to 2400 m2. Studying the number, density and age spectrum, determining the general, reproductive power of the cenopopulations showed that most of them have an exceptionally high coefficient, only
the populations of 5-6 have a bimodal spectrum with the maximum imposed vegetative and generative
individuals. The highest density of Oxytropis almaatensis species was noted in the cenpopulation №6 –
13.5±3.1 pcs./m2, the smallest in the coenopopulation №4 – 6,3±0,5 pcs./m2.
As a result of the study Oxytropis almaatensis cenopopulations was revealed that they are located
within their optimum, there is no special threat of extinction for this species. However, due to the fact
that Oxytropis almaatensis is a narrowly endemic species with a limited range, we recommend the
following activities: 1) Ile-Alatau National Natural Park should keep control and constantly conduct
monitoring work for all three populations of Oxytropis almaatensis in Trans-Ili Alatau mountains; 2) The
Institute of Botany and Phytointroduction should be introduced into its collections Oxytropis almaatensis species as a narrow endemic, rare species with a limited range.
