Abstract
Steppes and xeric meadows represent the most important element of zonal complexes in steppe and forest-steppe zones, as well as the corresponding altitudinal belts in mountains. These communities are floristically rich and extremely difficult to classify. The article revises the system of floristic classification of Siberian steppes and meadows representing the class Festuco-Brometea Br.-Bl. et R. Tx. in Br.-Bl. 1947. A formalized cluster analysis of 70 associations from Siberia, Kazakhstan, the Cis-Urals, the Urals and Trans-Urals was carried out (Fig. 1). Order Brachypodietalia pinnati Korneck 1974 (Syntax. syn. Stipetalia sibiricae Korolyuk et Makunina 2001) in Siberia and the adjacent regions of Kazakhstan unites communities of xeric meadows and meadow steppes. It includes 4 alliances and 27 associations.
