RARE PLANTS OF THE BOGDINSKO-BASKUNCHAK SALT DOME REGION RECOMMENDED FOR INCLUSION IN THE RED BOOKS OF THE RUSSIAN FEDERATION AND ASTRAKHAN REGION
Based on the field research conducted by the authors in the period from 1995 to 2022, a critical analysis of the literature data and herbarium material, a recommendation is made for making changes to the Red Book of the Astrakhan Region and the Russian Federation. We propose to change the rarity category of 6 and include 18 species in the Red Book of the Astrakhan region. It is also recommended to include in the Red Book of the Russian Federation 4 extremely rare species for Russia and the Bogdinsko-Baskunchaksky salt-dome region: Poacynum kazakevichchii, Diarthron vesiculosum, Eremoblastus caspicus, Thymus eltonicus.
