Steppes of the class Cleistogenetea squarrosae Mirkin et al. ex Korotkov et al. 1991 in Eastern Transbaikalia

Abstract

Transbaikalia is the vast region in Southern Siberia which includes numerous mountain ridges within the upper basins of the three big rivers, the Amur (Pacific Ocean basin), the Yenisey, and the Lena (Arctic Ocean basin). The most part of Transbaikalia territory is covered by woodlands, however, the steppes are an inherent component in the southern part of the region. Due to broad distribution they form the steppe and forest-steppe altitudinal belts in the mountains, and even totally predominate in the vast plains of the southeastern part of studied territory. Steppe communities occur throughout the broad range of habitats varying in humidity, edaphic conditions, and anthropogenic disturbance.
