However in many countries of Europe the areas of forests formed by black alder are scattered and often do not exceed 1–5 % of the forest cover due to both the small size of suitable ecotopes and their conversion to agriculture (Claessens et al., 2010). In the Moscow Region located in the center of the Russian Plain (Fig. 1), black alder forests also are about 5 % (Kotlov, Chernenkova, 2020) and have not been documented appropriately yet. Based upon 51 relevés two associations dominated by Alnus glutinosa from two vegetation classes were described using the Braun-Blanquet method. Ass. Urtico dioicae–Alnetum glutinosae Bulokhov et Solomeshch 2003 (class Alno glutinosae–Populetea albae Fukarek et Fabijanić 1968) (Bulokhov and Solomeshch, 2003; Semenishchenkov, 2016) includes floodplain hygro-mesophytic forests with nemoral species in herb layer (Table 1). This association is distributed in nemoral and broad-leaved coniferous zones of Eastern Europe. As a result of comparison with similar syntaxa from different regions of European Russia (Table 2) (Vasilevich, Stchukina, 2001; Sokolova, 2015; Semenishchenkov, 2016) its diagnostic species combination was enlarged by Impatiens noli-tangere, and new subassociation was described.

{"title":"West european geobotanists approaches to typology and mapping of vegetation territorial units","authors":"I. Lavrinenko","doi":"10.31111/vegrus/2021.42.146","DOIUrl":"https://doi.org/10.31111/vegrus/2021.42.146","url":null,"abstract":"The relevance of this paper for Russian geobotanists is due to the fact that until recently the author had regularly come across the statement that the phytosociological approach cannot be used in vegetation mapping and in legends for the geobotanical maps. In my opinion, such attitude towards the potential of the generally accepted and most widespread phytosociological approach in world practice significantly impoverishes Russian geobotany. And more seriously, it significantly reduces the possibility of using modern technologies and international experience in the field of vegetation mapping. In this regard, the purpose of the paper is to characterize the modern approaches of West European geobotanists to the typology of territorial units of vegetation based on phytosociological methods and their application to the plant cover mapping at different scales. Some of the most important stages in the development of this approach in West Europe are also reflected in the paper. In 1928 J. Braun-Blanquet in his work “Plant sociology” proposed the main directions for studying the structure and composition of territorial units of vege­tation. In the 1970s R. Tüxen laid the foundations of symphytosociology and proposed a method for transforming the system of syntaxa into sigma-syntaxa, and J.-M. Géhu and S. Rivas-Martínez, defined sigmetum as the basic unit of symphytosociology. The phytosociology of a plant landscape is based on the allocation of sigma-associations — combinations of plant communities and their complexes within homogeneous landscape units, giving it physiognomic originality. In landscape phytosociology, two main directions are currently distinguished: symphytosociology, with sigmetum (series, sigma-association) as main typological unit and tesela as territorial one, and geosymphytosociology with geosigmetum (geoseries) and catena, respectively. Thus, landscape phytosociology uses concepts that differ depending on the level of landscape organization: the level of series, or sigmetum (permaseries, curtaseries and, directly, series), and the level of geoseries, or geosigmetum — geopermaseries, geocurtaseries and geoseries). Each series/geoseries in relation to the water supply regime belongs to one of four types: climatophilic, tempohygrophilic, edaphoxerophilic, and edaphohygrophilic. Until the 1970s, only large-scale maps could be prepared on a phytosociological basis. They displayed homogeneous communities, predominantly of the association rank. Following the works of R. Tüxen, C. Beguin and O. Hegg, S. Rives-Martínez and J. M. Géhu, who substantiated the methodology of transforming the system of syntaxa into sigma-syntaxa based on phytosociological tables, sigmetum (series) and geosigmetum (geoseries) have become the main mapped units. It was during this period that a qualitative leap took place in geobotanical mapping, which made it possible to move from a large scale (1: 5–25 000), when communities of the association rank were highlight","PeriodicalId":37606,"journal":{"name":"Rastitel''nost'' Rossii","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69504238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Barguzin depression bottom is an area with sandy lands (Ivanov, 1960). This depression is one of the largest around the Lake Baikal (Florensov et al., 1965). Its internal field are accumulative surfaces, formed by Pleistocene sands, so-called “kujtuns” (Forest, Suvinsky, Lower, and Upper), are located as stripes of variable width, replacing each other from the north-west to the south-east (Fig. 2 A-D). Aeolian processes are most dynamic on weakly sod and bare sands: in the lower part of the Argada river, in the basins of Ina, Ulan-Burga, Zhargalanty rivers, and in the marginal parts of the steppe “kuytuns” (Fig. 3, 4). The results of aeolian processes are dunes and ridge-basin relief. This publication continues the series of papers (Dulepova, Korolyuk, 2013, 2015; Dulepova, 2016) on psammophytic vegetation of Baikal Siberia (Irkutsk region, the Republic of Buryatia, and the Trans-Baikal region). The paper is based on the analysis of 116 geobotanical relevés obtained in the course of the field studies in 2009–2014 in the Barguzinsky and Kurumkansky districts of the Republic of Buryatia. Four relevés are taken from the literature (Shchipek et al., 2002). Three diagnostic species of the class Brometea korotkiji Hilbig et Koroljuk 2000 (Bromopsis korotkiji, Corispermum sibiricum, Carex sabulosa) occur on the studied sandy lands. Among species of the order Oxytropidetalia lanatae Brzeg et Wika 2001 (Brzeg, Wika, 2001) such species as Artemisia ledebouriana, Chamaerhodos grandiflora, Oxytropis lanata have high constancy and often dominate in communities. When comparing new syntaxa with the previously described alliances (Oxytropidion lanatae Hilbig et Koroljuk 2000, Aconogonion chlorochryseum Dulepova et Korolyuk 2013 and Festucion dahuricae Dulepova et Korolyuk 2015) it was found that they are closer to the alliance Festucion dahuricae. However, Artemisia xanthochroa, Caragana buriatica, Festuca dahurica, Thymus baicalensis, and Ulmus pumila, commom in the Selenga river middle mountains, are absent in the study area (Korolyuk, 2017). The psammophytic fraction of the flora of the study area is not very peculiar. Only two endemic species (Oxytropis bargusinensis and Aconogonon bargusinense) are recorded on the sands of the Barguzin depression. 5 associations, 3 subassociations and 3 communities of the class Brometea korotkiji and 1 association of the class Cleistogenetea squarrosae Mirk. et al. ex Korotkov et al. 1991 (Table 1) are established as new.

So far syntaxonomy of arid regions of Russia are rather poor, only the Lower Volga valley is described in detail (Golub, 1994; Golub, Maltsev, 2013). The aim of present study was to carry out floristic classification of desert-steppe vegetation of the reserve territory. The study is based on the authors’ 133 relevés, made in 2019, and 41 published ones (Safronova, 2013). Cluster analysis was carried out (Ward’s method, Chekanovsky-Dyce-Sørensen coefficient). Two dendrograms, built on the species presence-absence and their cover, allowed to distibguish phytocenons and determine their differential species. At the first step, the dendrogram based on the species presence-absence was analyzed (Fig. 3). At levels from 2 to 8 clusters, the number of differential species with IV-V class constancy (Table 1) were assess. At the level of 3 clusters all relevés were divided into petrophytic, psammophytic and zonal communities (Table 2). According to large number of differential species two classes (Artemisietea lerchianae V. Golub 1994 — petrophytic desert-steppe communities and Festucetea vaginatae Soó ex Vicherek 1972 — psammophytic steppes) were distinguished. Also desert-steppe communities on fine soils which belong to the first class without own differential species were distinguished and their relevés were included in further analysis.

This species is included in the Red Data Books of Russia (2008), Leningrad Region (2018), St. Petersburg (2018), and Republic of Karelia (2007). The distribution of the communities in the studied area is as follows (Fig. 1) — the Yuntolovskiy reserve (the largest population), vicinity of the Lisiy Nos ­settlement, forest-park “Gagarka”, Tarkhovskiy Mys, Yuntolovskiy fo­rest-park (within St. Petersburg); vicinity of the Pesochnoe ­settlement, the Bolshoy Berye­zovyy Isl., near the port “Primorsk” (the Nor­thern coast of the Gulf of Finland) and the vicinity of Bolshaya Izhora ­settlement (Southern coast of the latter) in the Leningrad Region area. Communities are found mainly in coastal mires of various types (raised bogs, transitional mires, fens) in the place of former lagoons and in inter-dune depressions in different trophic conditions; most diverse in the last two. Communities are assigned into 12 associations, two of which with the shrub layer formed by Myrica gale. Sphagnetum myricosum galis is the most common association in transitional mires (Table 3). The communities are two-layers: Myrica gale shrub one and closed moss layer of Sphagnum species of diffe­rent ecological groups. The association is subdivided into 3 subassociations by dominanting Sphagnum species and groups of determinant species: sphagnosum angustifolii, sphagnosum flexuosi, and sphagnosum teretis. The communities of this association are located­ in newly formed mires, and their species composition is in the process of formation. These are succession stages between the fens and transitional mires. The ass. Myricetum caricosum lasiocarpae (table 4) includes communities of fens with close (50 to 80  %) Myrica gale shrub layer.

In the Russian Arctic, willow communities are most fully studied in Chukotka and Wrangel Isl. (Sekretareva, 1990, 1991, 1992, 1995, 2003, 2006; Sinelnikova, 2001); several associations are described in the Siberian Arctic (Zanokha, 2003; Telyatnikov et al., 2014, 2015), on the Kola Peninsula (Koroleva, 2006, 2014), while such studies have just begun in the East European tundras (Neshataev, Lavrinenko, 2020). Many researchers faced a dilemma as to which higher units should be assigned to the syntaxa of communities with shrub willows. They were placed in the Betulo-Adenostyletea Br.-Bl. 1948 (synonym Betulo carpaticae–Alnetea viridis Rejmánek ex Bœuf, Theurillat, Willner, Mucina et Simler in Bœuf et al. 2014), Salicetea purpureae Moor 1958, Scheuchzerio palustris–Caricetea fuscae Tx. 1937 nom. ambiguum (in cases of waterlogging) or Loiseleurio procumbentis–Vaccinietea Eggler ex Schubert 1960 (with a significant abundance of tundra species). Shrub willows are one of the most active plants in the southern and typical tundras of the East European sector of the Arctic. They not only form thickets with an independent high layer (willow scrub), but are also part of tundra and mire communities, in which they are located in one layer (up to 30 cm height) with herbs and dwarf-shrubs. We described 6 associations based on the analysis of 54 relevés made in 12 sites (Fig. 1) of the typical tundra subzone on the Kolguyev, Dolgiy and Vaygach islands and in the tundra near the Pechora River. Some of the described communities with Salix spp. can rightfully be called willow scrub.

The study is based on the analysis of 787 relevés made between 1989 and 2019. Relevés and their further analysis were performed according to the Braun-Blanquet aproach (Braun-Blanquet, 1964; Westhoff, Maarel, 1978). Two suballiances, 5 associations, 14 subassociations, 12 variants, and 1 facies were described in the alliance Aconito-Tilion. The combinations of diagnostic species were determined for each syntaxa. Nomenclatural types for new syntaxa are given in phytocoenotic tables and in the text. Сommunities of the alliance Aconito-Tilion are distributed meridionally from the southern taiga subzone (southern border of Perm Krai and Sverdlovsk Region), where they border with boreal forests. They are replaced by thermophilous oak forests of the alliance Lathyro pisiformis–Quercion roboris Solomeshch et Grigoriev in Willner et al. 2015 in the southern edge of the Ural Mountains and the Ural River basin of Orenburg Region (Fig. 1). In the latitudinal direction, forests of the alliance Aconito-Tilion are distributed in the forest-steppe zone of Bashkir Urals, Bugulma-Belebey Upland and foothills of western macroslope of Ural Mountains. Eastwards, they border hemiboreal light-coniferous–small-leaved herbaceous forests of the order Chamaecytiso ruthenici–Pinetalia sylvestris Solomeshch et Ermakov in Ermakov et al. 2000, class Brachypodio pinnati–Betuletea pendulae Ermakov, Korolyuk et Lashchinsky 1991. In the west, the communities of the alliance Aconito-Tilion are replaced by mesophytic broad-leaved forests of the­ ­alliance Querco roboris–Tilion cordatae Solomeshch et Laivinņš ex Bulokhov et Solomeshch in Bulokhov et Semenishchenkov 2015. According to floristic and structural-physiognomic characters, two suballiances were distinguished within this alliance. Suballiance Aconito lycoctoni–Tilienion cordatae suball. nov. combines broad-leaved forests typical for the region. Suballiance Tilio cordatae–Pinenion sylvestris suball. nov. includes pine–broad-leaved forests which represent ecotone communities in the transition stripe between European temperate broad-leaved forests of the class Carpino-Fagetea and Siberian hemiboreal light-coniferous–small-leaved herbaceous forests of the class Brachypodio-Betuletea. Suballiance Aconito-Tilienion (holotypus: Stachyo sylvaticae–Tilietum cordatae ass. Martynenko et al. 2005) includes broad-leaved forests growing near the eastern border of their range. In these forests, the main dominants of the tree layer are Tilia cordata, Ulmus glabra and Acer platanoides.

Matveyeva","doi":"10.31111/vegrus/2020.38.139","DOIUrl":"https://doi.org/10.31111/vegrus/2020.38.139","url":null,"abstract":"A list of species with an access of their “amount” (number of individuals, true/projective cover, biomass) on a plot of a standard size is the information that is necessary for an objective classification of plant communities, no matter what principles it is based on. Information on species composition, the variation both in their “amount” and constancy in the pool of geobotanical relevés is the basis for their clustering and the delimitation of syntaxonomical units. The only possible documents recording this information are geobotanical relevés, both published in the open press and stored in databases/archives. The completeness of species list within these depends on such parameters as time spent working in the field and technique (standard eye assessment at the sample plot (25 or 100 m2), a series of smaller (less than 1 m2) plots as well the researcher’s professionalism. The statement about the need to obtain a complete list of species in each stand seems an axiom, which is not fulfilled in practice. In Taymyr, when describing zonal communities for more than 2 hours, were recorded about 75 % of species, found on a permanent, carefully studied, sample plot of the same association. It is not necessary to comment that eye assessment of both composition and quantitative parameters are far fr om perfect. The same “amount” of species (abundance, cover) can be reflected differently not only by various researchers, but even by one, and not only in different years and areas, but as well in one season depending on such factors as what reléve was before, at what time of day (evening lighting in the Arctic is a serious factor), in what weather, etc. The result is influenced by factors such as the size and shape of a sample plot. The size is obvious: it should be no smaller than minimal area i. e. an area that gives an adequate idea of the composition of the described plot (Barkman, 1958, 1993). For the Arctic, according to the results of special work (Matveyeva, 1998), an area of 25 m2 was recommended for the species richest communities with a complex horizontal structure and 9 m2 for all others. The most frequent, generally accepted shape is a square. The use of another one depends on the community configuration: in narrow, elongated, winding, it must be “adjusted” to the outline of the stand, or it is better to abandon a single large plot in favor of several smaller ones. Location of the sample plot in space: preferably the most central, equidistant from the community boundaries. The smaller size of the community in general or its narrowness is fraught by the effect of visinizm (Barkman, 1958, 1990): the plot and therefore the list will get species of neighboring communities. No less problematic is the eye assessment of the species”amount”. It is generally accepted to evaluate projective cover, since neither to count the number of individuals, nor the determine of the true cover, and even more no biomass, in numerous relevés, is unrealistic.
