Halocnemeta strobilacei is represented by 4 classes of associations and 14 associations on the Caspian lowland within European Russia.Сommunities of Halocnemeta strobilacei are common in desert and steppe zones, in which they differ in species composition and occupied area.
The most common are the cenoses of Halocnemeta strobilacei pura association class. Communities of two classes of associations are characteristic: Halocnemeta strobilacei halosuffruticulosa and Halocnemeta strobilacei annuae. It is rare to find communities of another class of associations Halocnemetum strobilacei graminosa. Monodominant communities of Halocnemeta strobilacei are confined to soils with a high content of chlorine ions (Cl—). In soils under bidominant cenoses, in addition to chlorine ions (Cl—), natrium ions (Na+) and sulfate ions (SO42-) have a high content.
Keywords: communities, Halocnemeta strobilacei, dwarf semishrubs, annuals, classification scheme, Caspian lowland.
