Bioecological characteristics and importance of feed in xerophyts in the memorial desert plant of the Caspian coast

Abstract

In order to effectively use the natural ecosystem, the phytocenological structure of the region's vegetation was studied by conducting geobotanical research on the Caspian coast (in the territory of the Republic of Azerbaijan). Taxonomy and ecological-geobotanical map have been compiled. Morphological and ecological features of the species dominating the desert and semi-desert plant groups of the area were studied, as well as their phytocenological classification was developed at the level of type, formation and associations.
 The modern phytocenological classification of the studied vegetation not only protects the biodiversity of the area, but also provides a basis for its efficient use and protection. Taking into account the relief of the area and the diversity of soil and climatic conditions, it was determined by the phytocenological classification of vegetation that phytocenoses belonging to semi-desert, halophytic and psammophytic desert types are widespread in the vegetation of the Caspian coast.
 A new classification of Caspian coastal vegetation has been prepared with reference to our research and studies. According to this guideline and methodology, the classification of desert and semi-desert vegetation is based on eco-phytocenological principles, provided that the life forms of dominant and subdominant species, as well as the systematic taxonomic formations are named according to species and genera, as reflected in the descriptions recorded during field research.
 Thus, based on our geobotanical research and chamber studies, the modern classification of vegetation of the Caspian coast revealed that the plant species belonging to xerophytes in the natural phytocenoses of the area are Chenopodiaceae Vent., Asteraceae Dumort. and Poaceae Barnhart. are represented in the chapter.
