FLORISTIC DIVERSITY OF MOUNTAIN FORESTS OF THE MIDDLE AND SOUTH URALS

Abstract

Based on the results of long-term investigations, we present quantitative data on the biodiversity of conditionally native forests in the western low mountains of the Southern Urals and the Trans-Ural hilly foothill province of the Middle Urals. Available information about forest types is supplemented with information on the productivity and species abundance of the grass and shrub layers of conditionally native forests, which characterizes the natural level of biodiversity necessary to maintain the sustainability of natural ecosystems. It is revealed that the diversity of landscapes, humidification regimes and the complex ecotonic effect lead to a high variety of forest types. The analysis shows the advantages of sharing the methods of the genetic forest typology, landscape ecology, with obtaining quantitative characteristics of the productivity and ecosystem biodiversity and floral analysis for studying forest vegetation.
