Structure of the Botanical Diversity of the Utrish–Tuapse Variant of the Crimean-Novorossiysk Orobiom

Abstract

A regional assessment of the Crimean-Novorossiysk orobiome, which is considered a reference unit for the inventory and analysis of mountainous biodiversity, is based on the concept of ecosystem diversity. The altitudinal zonal structure of the vegetation cover is studied on the example of the Utrish–Tuapse geographic variant of the orobiome associated with the northwestern Caucasus, in accordance with which the spatial differentiation of flora and plant communities is formed. A quantitative substantiation of the biota and abiotic parameters characterizing the botanical and geographical uniqueness of the orobiome is given. The spectrum of altitudinal zonality of vegetation is determined, a quantitative assessment of floristic diversity by zones is given, and some features of the spatial structure of the diversity of communities in the mountainous area are shown.
