It is known that in the forest zone of both the European and Asian parts of Russia, the highest reed is found only as an invasive plant (Tzvelev, 2011). Communities dominated by P. altissimus are known both within its natural range and in the area of invasion. However, in syntaxonomic reviews, cenoses with this species dominanation are traditionally included by the authors in the ass. Phragmitetum australis Savich 1926 (Golub et al., 1991, 2015; Golub, Chorbadze, 1995; Kipriyanova, 2008; Vegetaсе…, 2011; Golovanov, Abramova, 2012; Chepinoga, 2015). The aim of this work is to establish the syntaxonomic status of communities formed by P. altissimus. The work used 65 geobotanical relevés made within the primary range of the P. altissimus (Astrakhan region and the south of the Tyumen region within the forest-steppe zone) and in the area of its secondary range (the Udmurtian Republic and the taiga zone of the Tyumen region). The relevés were introduced into database developed on the basis of the TURBOVEG program (Hennekens, 1996) and processed using the JUICE program (Tichý, 2002). To assess the abundance of species on the sample plots described, the J. Braun-Blanquet abundance scale was used with the following abundance-coverage scores: r — the species is extremely rare with insignificant coverage, + — the species is rare, the degree of coverage is small, 1 — the number of individuals is large, the degree of coverage is small or the individuals are sparse, but the coverage is large, 2 — the number of individuals is large, the projective cover is from 5 to 25 %, 3 — the number of individuals is any, the projective cover is from 25 to 50 %, 4 — the number of individuals is any, the projective cover is from 50 to 75 %, the number of individuals is any, the cover is more than 75 % (Mirkin et al., 1989). Syntaxonomic analysis was performed using the approach suggested by J. Braun-Blanquet (1964). The names of syntaxa are given according to the “International Code of Phytosociological Nomenclature” (Theurillat et al., 2021). The system of higher syntaxa is given in accordance with “Hierarchical floristic classification…” (Mucina et al., 2016). To identify the main factors determining the differentiation and distribution of the studied communities, the NMDS method was used. For each syntaxon, using the IBIS program (Zverev, 2007), the average indicator values were calculated according to the ecological scales of D. N. Tsyganov (Tsyganov, 1983): soil moisture (Hd), soil nitrogen richness (Nt), and illumination-shading (Lc). Processing was carried out in the PC-ORD v. 6.0 (McCune et Mefford, 2011).

At the beginning of the XXI century geobotanical research was actively continued, while significant attention was paid to phytocenoses located within the towns and villages of the republic (Govorov, 2004; Edrenkina, 2005; Yamalov et al., 2008; Yamalov, Suyundukova, 2008; Usmanova et al., 2013, 2014). Urban vegetation is most fully presented in the series of publications on the classification of vegetation of towns of the Southern industrial zone (Golovanov, Abramova, 2012, 2013; Golovanov et al., 2017). The given article presents results of the long-term (2005-2018) research of vegetation of the towns of Bashkir Pre-Urals, as well as rural settlements of Trans-Urals. 63 complete relevés of new communities for RB included in the geobotanical base of synantropic vegetation of the Southern Urals were used. The geobotanical database was implemented using the TURBOVEG software (Hennekens, Schaminée, 2001). The area of relevé depended on the community size and homogeneity. Classification is carried out according to Braun-Blanquet method using the JUICE software (Tichý, 2002). The identification of new syntaxa was carried out in accordance with the “International Code of Phytosociological Nomenclature. 4th edition” (Theurillat et al., 2021). The names of the higher syntaxa are given by “Vegetation of Europe...” (Mucina et al., 2016). The ecological conditions were assessed with use of average values of E. Landolt (1977) ecological scales and processed by IBIS software (Zverev, 2007). Average values are calculated on the following scales: humidification (M), acidity (R), soil richness with mineral nutrition elements (N), humus (H) content, mechanical composition and soil structure (D), illumination (L). At the beginning of the 2010s prodrome of synanthropic communities of RB, included 7 classes, 12 orders, 17 alliances and 61 associations (Yamalov et al., 2012). Currently, the synthaxonomy of the synanthropic vegetation of the study area requires adjustment in accordance with the modern state of European synthaxonomy. Special geobotanical studies of recent years have allowed expanding the synthaxonomic scheme of synanthropic vegetation of the region. Earlier, data have already been published on new associations for the region of the classes Artemisietea vulgaris and Galio-Urticetea (Golovanov, 2017). This article extends our research. This article considers the synanthropic vegetation of two synanthropic classes — Sisymbrietea and Digitario sanguinalis–Eragrostietea minoris.

As the zonal steppe ecosystems are totally destroyed and transformed, petrophytic cenoses represent the predominant type of natural vegetation. They are of high conservation importance due to preserving unique biodiversity with a large number of rare and endangered species, relics and endemics (Ryabinina, 2003; Yamalov et al., 2019). Stony steppes in the Southern Urals have been studied for more than 100 years. Initiated in the 1980s, the syntaxonomical research covers now only the limited territories, mainly within the protected areas (Unikalnye ..., 2014; Prirodnye ..., 2018). The recent studies are focused on the relationship between the petrophytic vegetation and macroecological gradients in the context of geographical zonation (Zolotareva et al., 2019; Korolyuk et al., 2020). Our study presents the results of the analysis of 265 relevés of petrophytic communities of the steppe zone, carried out by the authors on the territory of the Gaysky, Kuvandyksky, Saraktashsky and Belyaevsky administrative districts of the Orenburg region, as well as the Khaibullinsky district of the Bashkortostan Republic in 2014–2018 (Fig. 1). Six phytocoenons were identified using the TWINSPAN algorithm followed by manual sorting. They represent the main diversity of petrophytic vegetation in the studied region and differ in the groups of species identified by formal criteria (Korolyuk et al., 2016; Zolotareva et al., 2019). We conducted the cluster analysis to compare these with the petrophytic associations of the Urals: 26 associations from the classes Festuco-Brometea Br.-Bl. et Tx. ex Soó 1947 and Anabasietea cretaceae Golovanov et al. 2021 (Fig. 2, 3). Five communities were assigned to the steppe vegetation, and their position in the syntaxonomical system was determined. Communities 1–3 regarded as typical steppes have similar floristic composition and dominant plants; community 4 is closer to the rich forb-bunchgrass steppes; community 5 and the ass.

Ecologists have come to understand that the best way to ensure the conservation of populations of organisms and their communities is to preserve the environment in which they live. The countries of the European Community, where special programs have been developed since mid 1980s, have shown the greatest activity in preserving environmental conditions. Currently, the «European Union Nature Information System» (EUNIS) has become the most popular among such programs. Habitat is a central concept in EUNIS. For the purposes of EUNIS, habitat is defined asa place where plants or animals normally live, characterized primarily by its physical features (topography, plant or animal physiognomy, soil characteristics, climate, water quality etc.) and secondarily by the species of plants and animals that live there (Davies et al., 2004). Most often, habitat is considered to be synonym of the term biotope. The EUNIS biotope classification would correspond to the ecosystem classification if heterotrophic components were largely present in it. However, at present, these organisms, are not used for classification of terrestrial ecosystems. The latter (especially benthos) are important in the characterization of marine habitat types.\u0000The author does not deny the extreme importance of the EUNIS habitat classification for ecological science and solving problems of nature conservation. He is only sure that the concept of habitat classification began to be developed in the Soviet Union as early as 1920–1930th in the papers by L. G. Ramenskiy who in 1927 published the definition of habitat type: The type of habitat or natural area is determined by a combination of climate conditions, relief, irrigation, and the nature of the soil and subsoil. The same type can be covered by a meadow, or a forest, or plowed up, etc.: these are its transitional states (in virgin untouched nature, each type is inhabited by a completely definite combination of plants - steppe, forest, meadow, etc.). Afterwards L. G. Ramenskiy began to use the term land type instead of habitat type.\u0000In the 1930s, by the land type he meant an ecosystem unit in which plant community would exist without human influence. The land type in nature is represented by a set of various modifications that arise, as a rule, under man pressure. Modifications can transform into each other and revert to the original state of the type. Later, such plant community was called potential vegetation (Tüxen, 1956). In 1932–1935, L. G. Ramenskiy supervised the inventory of natural forage lands in the USSR, which used this concept of land type (Golub, 2015). The inventory of natural forage lands in the USSR resulted in their hierarchical classification: 19 classes and 43 subclasses were established.

Chalk outcrops are unique botanical-geographical sites located in steppe and desert zones of Eurasia. Specific communities of calcephyte plant species have spread in these areas, in places of outcrops or close occurrence from the surface of upper-Cretaceous carbonate rocks. The flora of chalk outcrops is characterized by a great amount of rare species, mainly ende­mic, associated with peculiar substrates, the locality of habitats, and the historical past of the area of outcrops location (Matyshenko, 1985) The history of the study of flora and vegetation of chalk outcrops is given. Synthaxonomic studies of chalk vegetation as part of the ecological-floristic approach cover only territories west of the Volga river (Poluyanov, 2009; Averinova, 2011, 2016; Demina, 2014; Demina et al., 2016; Didukh et al., 2018). Chalk highlands of the North-West Kazakhstan and adjacent regions of the Russian Federation occupy quite large areas. However, up to date, there is no data on the vegetation diversity of these territories based on complete geobotanical relevés, that is why their synthaxonomy remains undeveloped. The study area with 15 massifs of chalk outcrops (Fig. 1) includes the Orenburg region (Novosergievsky, Perevolotsky, Sol-Iletskiy, Akbulak and Gaysky districts), and Aktobe (Hobdinsky, Uilsky and Bayganinsky district) and Atyrau (Zhylyoysky district) regions of the Republic of Kazakhstan. The largest massifs in the Orenburg region of the Russian Federation are: Starobelogorskie (Fig. 2), Chesnokov­skie (Fig. 3), Verkhnechibendinskie (Fig. 6), Troits­kie (Fig. 7), Pokrovskie Chalk Mountains (Fig. 4) and Durtel mountain (Fig. 5). Chalk massif Akshatau (Fig. 8) and the range Aktolagai (Fig. 9) are the largest within Aktobe region. The investigated sites are mostly located on the Sub-Ural Plateau, which extended from the southern regions of the Orenburg region to the Emba River in the territory of Aktobe region. They are less common within the Obschiy Syrt and sporadic in the Guberlinskie mountains. The study area covers a wide range of zonal vegetation from dry steppes in the northern part of the gradient to northern deserts in the southern one. The dataset includes 270 relevés of chalk outcrops communities performed by the authors in 2014–2019. The primary classification was carried out using TWINSPAN algorithm. As a result three groups of communities are established. The first group is communities of the Emben Plateau, the most southern area; second is communities on relatively developed soils in the slopes bases, depressions between chalk ridges and on their flat tops; third is widespread communities on most of the Podural Plateau and Obschy Syrt, excluding the Emben Plateau.

Special attention was paid to fir (Abies sibirica) forests as well as larch (Larix sibirica) forests and woodlands due to the luck of data on their diversity. The study following both traditional (Polevaya…, 1964) and modern (Ipatov, Mirin, 2008) approaches of geobotanical and floristic researches is based on 168 original relevés (on sample plots of 400 m2 or within the community limits). The geobotanical data set which contains 184 relevés is stored in the archive (phytocoenarium) of the Institute of Biology (above). The community vertical and horizontal structure as well as the diversity and abundance of vascular plants, bryophytes, and lichens were under study. Ecological-phytocoenotical (dominant) approach was used for classification of larch forests and woodlands in the study area using both the author’s and literature data (Yudin, 1954; Gorchakovskiy, 1966; Nepomilueva, 1974; Martynenko, 1999; Neshataeva, Neshataev, 2005; Rysin, 2010; Kucherov, 2019). Larch forests and woodlands of the study area belong to the Montano-Lariceta subformation of the Lariceta sibiricae formation, which belongs to the Therhodendrosa vegetation subtype of the Aciculilignosa vegetation type (Bykov, 1960). The list of syntaxa for subformation Montano-Lariceta (M.-L.) includes 20 associations, 2 subassociations, 23 variants, and 3 community types from 5 forest types — lichen, green moss, herbaceous, hair cap moss and sphagnum ones. Three associations are transitional between various types of forest (Table 2–6, Fig. 2–10). Forest types of this subformation are allocated in different ordination areas of ecological space according to vectors of soil nitrogen content and light (Table 7, Fig. 11). Larch forests and woodlands of type M.-L. cladinosa occur in dry habitats with poor acidic soils, while phytocenoses of M.-L. polytrichosa and M.-L. sphagnosa are common on wet poor and acidic soils and those of M.-L. hylocomiosa on more fertile soils. In the study area, they do not occupy large areas. The communities of type M.-L. herbosa are common in low elevated mesophyte habitats with more fertile soils. Communities of M.-L. hylocomiosa and M.-L. herbosa types widely occur both in mountain forest and woodland altitudinal belts at the western macroslope of the Subpolar Urals northward N 64°. The use of environmental scales and statistical methods to identify classification units of lower rank did not give well-interpreted results.

Zonal communities are species-rich grasslands (Isachenko, Rachkovskaya, 1961; Lapshina, Lavrenko, 1985), but due to relief and geological substrates there are numerous isolated saucer-shaped suffosion depression among flat steppe landscape occupied by small (0.5–1.5 ha) forest massifs. Previously such landscapes were described as “false forest-steppe” or “kolok steppe” following local term “kolok” that is the forest “island”. In some areas such “forest islands” occupy up to 20 % of whole area that makes difficult to identify the border between steppe and forest-steppe zones, in particular in anthropogenically transformed landscape. Until now, there is no information on the structure and floristic composition of such forests, except for brief mentiones in papers on steppe vegetation. The main aim of this paper is to assess the diversity of the deciduous forests in the steppe zone within the study area and establish their syntaxonomical position in the floristic classification. The research is based on 376 original relevés performed by authors in 2007–2016 years in steppe zone from Urals on the west to the Ob river valley on the east.

Diagnostic species are the same as for class. There are two alliances differing in geographic distribution and habitats within the order. Alliance Sileno nutantis–Betulion pendulae all. nov. hoc loco. Nomenclature type (holotypus hoc loco) is the ass. Sileno nutantis–Betuletum pendulae ass. nov. hoc loco. Diagnostic species: Adenophora lilifolia, Campanula bononiensis, C. wolgensis, Euphorbia subtilis, Galium boreale, Plantago urvillei, Xanthoselinum alsaticum. Association includes deciduous, mostly birch, forests which occur on well-drained plains as small massifs in river valleys and in suffosion depressions. There are four associations differing by habitat moistening within the alliance. Ass.

The first results of the ecological and floristic classification of basic crop communities (wheat, barley, oats, corn, potatoes, peas, rapeseed etc.) in six botanical and geographical regions of the taiga and forest-steppe zones (Kulikov et al., 2013) within the Sverdlovsk region, based on the analysis of 160 relevés performed by A. S. Tretyakova, P. V. Kondratkov and N. Yu. Grudanov in 2019, are presented. Communities are classified within the order Aperetalia spicae-venti J. Tx. et Tx. in Malato-Beliz et al. 1960 of the class Papaveretea rhoeadis S. Brullo et al. 2001 nom. conserv. propos. and assigned to the alliance Scleranthion annui (Kruseman et Vlieger 1939 nom. conserv. propos.) Sissingh in Westhoff et al. 1946), which represents the most mesophytic types of weed vegetation in the Urals. Three associations allocated in alliance (two for the first time): Solano nigri–Erodietum cicutarii ass. nov. hoc loco (Table 2, syntaxon 7; Table 4); nomenclature type (holotypus hoc loco) — Table 4, rel. 11 (number in database — 25): Sverdlovsk Region, Sysertskiy district, Kunarskoe village environs, 23.07.2019, authors — A. S. Tretyakova, P. V. Kondratkov);Lamio amplexicaulis–Stellarietum mediae ass. nov. hoc loco (Table 2, syntaxon 8; table 5; nomenclature type (holotypus hoc loco) — Table 5, rel. 10 (number in database — 27): Sverdlovsk Region, Sysertskiy district, Shaidurovo village environs, 22.07.2019, authors — A. S. Tretyakova, P. V. Kondratkov); ass. Euphorbio helioscopiae–Fumarietum officinalis Khasanova et al. 2018. The last one includes two variants. Two unranked communities are also described. Distribution areas of syntaxa cover the southern taiga and pre-forest-steppe pine-birch forests subzones of the taiga zone and the northern forest-steppe subzone of the forest-steppe zone. Habitats are confined mainly to gray forest soils, in rare cases — leached chernozems. The mostly wide distributed is the ass. Euphorbio helioscopiae-Fumarietum officinalis, also common to the south of the study area, in the Republic of Bashkortostan. Аss. Lamio amplexicaulis–Stellarietum mediae is identified in five botanical and geographical districts within the Sverdlovsk region. The confluence with crops and the accompanying system of agriculturе is different. The species composition of the established syntaxa was compared with the associations of the alliance Scleranthion annui described earlier in the Republic of Bashkortostan. The species richness of the latter is generally higher. Differences in species composition of diagnostic groups were revealed.
