DISTRIBUTION AND PHYTOCENOTIC CHARACTERISTIC OF СAKILE EUXINA POBED. IN THE COASTAL PART OF AZERBAIJAN (SOUTH CAUCASUS)

Abstract. The article characterizes the psammophyte-littoral species Cakile euxina Pobed, which has recently appeared in Azerbaijan. Data are given on the distribution of the species along the coastal strip, vegetation, and plant communities with the participation of the species are described.The main concentration of the species is observed in the northern, bordering Russia (Dagestan)part of the coastal strip. It has been established that Argusiya sibirica + Convolvolis persica is a characteristic community for Сakile euxina in all parts of the Caspian Sea since both species areecologically confined to the same sandy habitats as the object of our study. In addition to participationin this main community, Сakile euxina in the northern part is found in the communities of Artemisiaannua + Сonvolvulus persica, Melilotus oficinalis + Artemisia annua, Xanthium strumarium +Сakile euxina, Salicorniaeuropea + Suaeda confusa, Salsola tragus + Convolvolis persica, Artemisiaarenaria + Herbosa, in central Astragalus ign arius + Calligonum bakuense, Juncus acutus + Elaegnus angustifoliа, Salicornia europea + Suaeda confusa, and in the south - mainly in the above-mentioned community and in various forb groups. It has been established that C. euxina actively participates in annual saltwort communities dominated by Suaeda confuza Iljin, common in areas with wet sandsand sandstones, typical for the northern and central parts of the coast. For C. euxina, the optimalsoil moisture conditions were found, which are in the range of 45-75%. Monitoring observationshave shown that at present the plant is under the strongest influence of human economic activity.The organization of numerous beach areas, cafes, hotels and other residential complexes limit the range of the species in the coastal strip of the republic.
