Using the Braun-Blanquet approach, 7 plant communities of forests and 3 communities of krummholz were distinguished on the Svyatoi Nos Peninsula on the eastern coast of Lake Baikal. Dominant species of these communities are Abies sibirica, Larix sibirica, Pinus sibirica, P. sylvestris, P. pumila and Betula divaricata. The data from Svyatoi Nos were combined with all the available data from the northern part of the Republic of Buryatia (289 releves) and classified into 23 communities. These have been assigned to the following alliances: Aconito rubicundi-Abietion sibiricae - floodplain forests with tall forbs and the relict occurrence of a few nemoral species, Pino sibiricae-Laricion sibiricae - mesic forests with (sub-Atlantic-) boreal species and abundant mosses, Vaccinio-Pinion pumilae - krummholz communities of NE Asian distribution, Cladonio stellaris-Laricion gmelinii - Larix gmelinii dominated open forests on permafrosts with NE Asian distribution, and Hieracio umbellati-Pinion sylvestris - xeric forests with southern Siberian species. Phytogeographical affinities of these alliances are discussed and a system of high-ranked syntaxa (orders, classes) is proposed for the northern Buryatian forests and krummholz.
Syntaxonomy of vegetation of Svjatoj Nos peninsula, lake Baikal. 1. Non-forest communities
Natural and semi-natural plant communities of S vjatoj Nos Peninsula on the East coast of Lake Baikal, Eastern Siberia, Russia, are classified and described using the methods of Braun-Blanquet phytosociology. A total of 48 associations and communities were recognized, comprising alpine tundra, subalpine forb vegetation, aquatic macrophyte vegetation, tall-herb and poor fens, mires, bogs, meadows, sand-dune and steppe vegetation. Twenty six syntaxa of ranks ranging from subassociation to class are described or validated for the first time. All communities are documented by phytosociological releves.

The classification of forests in the Bolshoy Agul river basin (Eastern Sayan) was developed using the Brawn-Blanquet method and cluster analysis. Two zonal forests categories in North Asia – boreal forests of the Vaccinio–Piceetea Br.-Bl. in Br.-Bl. et al. 1939 and hemiboreal forests of the Rhytidio–Laricetea Korotkov et Ermakov 1999 were revealed. Boreal coniferous forests are represented dominantly by two orders of the East Siberian-Mongolian type – Ledo–Laricetalia Ermakov et Alsynbayev 2004 and Lathyro–Laricetalia Ermakov et al. 2002. The first order includes alliance Pino sibiricae–Laricion Ermakov et Alsynbayev 2004 and two associations – Carici globularis–Pinetum sibiricae ass. nov. and Linnaeo–Pinetum sibiricae ass. nov. occurring on long-term frozen soils with different moisture regimes. The second order of the East Siberian-Mongolian type is represented by community Senecio nemorensis – Larix sibirica(Rhododendro–Laricion Ermakov in Krestov et al. 2009). The third order of...
Syntaxonomy of steppe depression vegetation of Ukraine
Vegetation Classification and Survey, 2021
Aims: To revise the syntaxonomy of the vegetation of steppe depressions (pody), in particular (1) to identify the associations and to reveal their environmental, structural and compositional peculiarities; (2) to assign the associations to higher syntaxa; and (3) to correct nomenclatural aspects according to the ICPN.Study area: Steppe zone of Ukraine, Left-Bank of the Lower Dnieper basin.Methods: 641 relevés were included in the final analysis in the PCOrd program integrated into Juice software. Two expert systems (EVC and EUNIS-ESy) were used to assign relevés to vegetation classes and to EUNIS units.Results: The analysis resulted in nine clusters, which were interpreted asFestuco-Brometea(two units),Molinio-Arrhenatheretea(three units),Isoёto-Nanojuncetea(three units) and one derivate community of theFestuco-Puccinellietea. Detailed characteristics of the species composition, structure, distribution, and environmental conditions are provided for each unit. According to the DCA or...

⎯An ecological ordination model of higher units of steppe vegetation in the mountains of the southern Middle Siberia was created based on indirect ordination (detrended correspondence analysis) of 326 complete geobotanical descriptions and on a correlation analysis of the values of main axes with climatic, soilground, and geographical parameters. Ecological series of coenofloras of the steppe vegetation are observed in the space of the two first leading axes of ordination. They are oriented by climatic factors of the annual and seasonal precipitation amounts, temperature, oceanity-continentality, and substrate rockiness. A syntaxonomic interpretation of the observed ecological-geographical steppe types is given, and a hierarchy of higher classification units is substantiated from ecological positions.
Classification of meadows of the South Siberian uplands and mountains
Folia Geobotanica, 1999
The classification of South Siberian meadows using the Braun-BJanquet approach was carried out on the basis of a geographically wide-ranging data set from the West Siberian Plain and the Aitai-Sayanian mountain systems. Two main phytosociological types of meadows were distinguished within the class Molinio-Arrhenatheretea. The natural Siberian forest meadows were included in the order Carici macrourae-Crepidetalia sibiricae comprising two alliances (Crepidion sibiricae, Aconito barbati-Vtcion unijugae) and 7 associations. The anthropogenic types of dry meadows were included in the European-West Siberian order Arrhenatheretalia, comprising one alliance (Festucion pratensis) and 5 associations. DCA ordination revealed clear differences in the floristic composition of the higher units and in the diagnostic importance of the main ecological and phytosociological species groups.
