TO THE STUDY OF VEGETATION COVER IN THE VICINITIES OF PIREKYASHKYUL MUD VOLCANO (AZERBAIJAN)
Shabnam Q. Isayeva

The vegetation cover of the mud volcanoes of Azerbaijan is still unexplored. In this article we present the results for comprehensive floristic and geobotanical investigation. We identified and analyzed the plant species composition of the Pirekyashkyul mud volcano, located in the Gobustan botanical and geographical area. It has been established that the vegetation cover of the volcano is characterized by low floristic diversity, which consist of 18 species of vascular plants from 16 genera and 7 families. By the method of phytosociological profiling, patterns of distribution of plant communities and groups in the territory adjacent to the mud volcano Pirekyashkyul were revealed. The number of species in phytocoenosis and their total projective cover increase from the periphery to the middle part, at the center it decreases sharply to one species. A pronounced mosaic of the vegetation cover associated with temperature gradient, wind direction, substrate moisture regime, and sides of the horizon is observed. The vegetation cover of the mud volcanos is specific, but there is no sharp difference from the vegetation of the territory.
