FLORA OF THE WESTERN CISCAUCASIA AND THE NORTH-WESTERN PART OF THE GREATER CAUCASUS AND ITS SPECIFICITY
The issue of the inventory of Western Ciscaucasia flora and north-western part of the Greater Caucasus corresponding to the four districts and seven floristic regions are given. The question of the specificity of flora: the high level of species diversity, which is associated with a complex genesis of the flora, the position of the region in southern Russia on the border of Pontian, Mediterranean, Near Eastern and Caucasian floral centers considers. The second important feature of the flora of the region is the high level of endemism, due to the manifestation of the island effect variegation physiographic conditions and hybridogenesis. The region has unique phytocenotic diversity. There are many original florocenotic complexes characterized by a great variety of species and communities. The fourth feature is the transformation of flora under the influence of anthropogenic factors that led to the deformation of flora and reducing and loss of native species, the process synanthropization, wide introduction of invasive species, even to the degradation of entire floral complexes. The specific flora considers against other flora of the Russian part of the Caucasus. The annotated list of the vascular plants has about 3700 species presumably. Ten leading families accounted 57.5% of vascular plants specific flora.
