Study of rare and endangered species of the Astragalus L. genus in the natural flora of Azerbaijan

In the study, analysis of 29 rare and endangered plant categories of 156 species of Astragalus L. naturally distributed in the flora of Azerbaijan, was conducted. The study found that the area of most species is much smaller than in previous years, and the gene pool of some is endangered. The article provides information on the habitats, biological characteristics, reserves, reasons for changes in natural resources and conservation measures. In the research work, 15 species of Astragalus L. genus were included in the book “Rare Trees and shrubs of Azerbaijan” (2016). As a result of our research, it was determined that 30 new species of the Astragalus L. genus have a small area because of the exposure to anthropogenic factors, and very rare in nature due to lack of special protection. In carrying out the necessary protection measures in the studied species, it was found that 7 new species are endemic, and 23 species are recommended to be included in the Red Book of Azerbaijan as endangered shrubs and plants.
