le 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. lt has been established that Argusiya sibirica + Convolvolis
persica is a characteristic community for Cakile euxina in all parts of the Caspian Sea since both
species are ecologically confined to the same sandy habitats as the object of our study. ln
addition to participation in this main community, Cakile euxina in the northern part is found in
the communities of Artemisia annua + Convolvulus persica, Melilotus oficinalis + Artemisia
annua, Хanthium strumarium + Cakile euxina, Salicorniaeuropea + Suaeda confusa, Salsola tragus +
Convolvolis persica, Artemisia arenaria + Herbosa, in central Astragalus igniarius + Calligonum
bakuense, Juncus acutus + Elaegnus angustifolia, Salicornia europea + Suaeda confusa, and in the
south - mainly in the above-mentioned community and in various forb groups. lt has been established
that C. euxina actively participates in annual saltwort communities dominated by Suaeda confuza
lljin, common in areas with wet sands and sandstones, typical for the northern and central parts of
the coast. For C. euxina, the optimal soil moisture conditions were found, which are in the range
of 45-75%. Monitoring observations have shown that at present the plant is under the strongest
influence of human economic activity. The organization of numerous beach areas, cafes, hote
l complexes limit the
range of the species in the coastal strip of the republic.
