Biodiversity is important for maintaining of forest ecosystems functioning and in their resistance to anthropo-climatic challenges. Assessment of species diversity and species ecomorphic analysis is the basis for determining their current status, rational use and protection. At the end of the nineteenth century, Belgard A. L. (1950) in his system of ectomorphs using terminology presented by Dekandol (1956) and Warming (1903), had proposed a «trophomorph» category that reflected species relation to soil richness. Analysis of trophomorphs reflects diversity of soil conditions in different biotopes within forest ecosystems. The article gives an analysis on vascular plant trophomorphs distribution in various forest biotopes of Oril river valley. Flora and vegetation surveys in forests of Oril river valley were carried out by A. L. Belgard and T. F. Kirichenko since the 30s of the 20th century. The latest data on forest vegetation state within the Oril river valley were given in the works of Y. Gamulja and V. Manyuk. Generalized bioecological analysis of flora Oril river valley was represented in the monograph of B. Baranovsky, V. Maniuk, I. Ivanko, L. Karmyzova «Flora analysis of the Oril National Park». As is known, edaphic conditions of plant habitats in a first place are determined by soil fertility depending on the plant nutrients availability. Soddy-forest soil on sandy terrace of Oril river valley has a relatively low content of humus and total nitrogen: 2 and 0.04 %. Under these conditions, pine phytocenoses were ocсurred that represented exclusively by artificial plantings. Soils in the depressed area of Oril river floodplain are much richer in humus and nitrogen content (10 and 0.37 %). Here, arboreal and shrubby vegetation is represented by communities with common oak. On the second terrace of Oril river valley, forest vegetation is represented by artificial pine forests. Microcenoses with black locust, amorpha and willow occurred on elevated areas of sandy terrace (arena). In the depressed area of the arena, microcenoses with aspen and birch, aspen, Tatarian maple, amorpha, black locust were occurred additionally to pine communities. In the Oril floodplain, native arboreal and shrubby vegetation is represented mainly by communities with common oak. In depressed areas of the floodplain, microcenoses with white poplar, black poplar, aspen, Tatarian maple, amorpha, willow (Salix alba, S. fragilis), osiery (Salix cinerea, S. triandra),  and alder are fragmentarily occurred. In conditions of elevated areas of the floodplain, 196 vascular plants species were found, and 105 species in depressed areas. On the second terrace, 38 plant species grow on the elevated areas, and 54 species on the depressed ones. Flora includes 45 adventive plant species. In depressed floodplain areas, oligotrophs are represented by 7 species, mesotrophs by 126 species, megatrophs by 50 species, and in elevated areas: 7, 126 and 25 species, respectively. In depressed areas of arena oligotrophs are represented by 4 species, mesotrophs by 29 species, and megatrophs by 11, elevated areas: 7 and 21 species respectively, and megatrophs were absent.

The paper contains a synopsis of rare component of flora of Halych National Nature Park forest ecosystems, as well as evaluation of distribution trends of rare vascular plant species and the state of their populations. Being established in 2004, the Park is located in Halych district of Ivano-Frankivsk region on the area of 14684.8 ha. Forests occupy the biggest part of its territory (81.1 %), among which predominate poor and mixed oak (Querceta roboris), beech (Fageta sylvaticae) and hornbeam (Carpineta betuli) woods. Inventory check of plant cover of the forest ecosystems has been done between 2008-2019 years. According to the results of our study, within the forests and forest margins grow 303 vascular plant species, out of which 63 are rare (20.8 %). The list of rare species is composed of species included to the Red Data Book of Ukraine, of species protected by international conventions and directives and complemented by species that are threatened within the study region. Species were considered as threatened if the number of localities and / or population size were small. Regionally rare species were selected based on the analyzes of results of our field survey and materials of herbarium collections. We have found that the third part of rare species (33.3 %) has high coenotic amplitude and a bit less species (26.2 %) favor forest margins. Rare species having low coenotic amplitude are confined to beech woods (19.1 %). Rare species are considerably distinguished by occurrence. Species with scarce occurrence predominate. For instance, 61 % of the species were found in 1-5 localities, of which 25 species occur only in one or two sites. Share of species growing in 6-10 localities within the Park is equal to 26.6 %. Only a small percentage (6.2 %) of rare species comprises species with relatively frequent occurrence (11–20 localities as well as more than 20 cites). Rare species of the Park forests with the highest occurrence rate are Lilium martagon and some members of Orchidaceae family. Predominantly, rare species have populations of small size, for instance, 81.2 % of the species were found in quantities of a few plants – several hundreds of individuals. The most threatened are species general number of which at the Park area is several plants (15.6 %). These species are as follows: Circaea alpina, Atropa bella-donna, Campanula latifolia, Phyteuma spicatum, Epipactis atrorubens etc. The biggest groups comprise species with general number of few tens and several hundreds of individuals (totally 65.6 %). Species with big populations represent far smaller part of forest rare species. Nine rare species grow in the number of several thousands of plants within the Park and three species (Allium ursinum, Galanthus nivalis and Leucojum vernum) – over a million. It has been established that 52.4 % of rare species populations taken together remain in critically bad state, 28.6 % of the populations – in bad state, 14.3 % – in satisfactory state. Only 4.8 % of populations are in good state. Our results show that about 95 % of species are in need of protection and continuous monitoring of population number. Furthermore, 51 species of rare plants,having low number and bad state of populations, require to work out and implement management plans for their restoration. Key words: rare species, vascular plants, population state, species occurrence, population number

The Impact

Conducting soil studies are relevant in determining the subordination of forest types and biodiversity of vegetation to soil taxa, in determining the dependence of basic forest stand productivity from soil conditions, in creating a land registry and economic assessment of forest land, in studying the soil evolution of forest plantations under the impact of anthropogenic influences. Soil is the most important environmental factor in shaping the productivity and biodiversity of forest phytocenosis. The study of forest soils is also important in terms of basic research of their genesis, evolution. The article presents the results of research of soil conditions of vegetation growth of forest ecosystems of northern regions of Volga of the Republic of Tatarstan. The main types of forest soils are characterized in the paper. The studied forest formations grow on various soils on genesis and forest vegetation properties: sod-podzol, gray forest, brown forest, brown forest sandy, alluvial meadow, rendziny soil. The granulometric structure of soils varies from sandy to the clay. The well structured soils are formed on loamy layers under forest phytocenosis canopy. Pine and spruce ecosystems have a medi-decomposed litter of moder and multi-moder types; linden, oak, birch and aspen biogeocoenoses have strong-decomposed litter of multi type, that characterizes the intense biological cycle of substances in forest ecosystems. The wide range of place conditions of territories causes the biological diversity of forest vegetation at the level of species and ecosystems.

Abstract The current conservation status of the rare vascular plant species and rare forest communities of the Volyn Upland (Ukraine) was characterized and analyzed. We found 14 rare plant species belonging to the Red Data Book of Ukraine in this territory (Lycopodium annotium L., Allium ursinum L., Cephalanthera longifolia (L.) Fritsch, Cephalanthera rubra (L.) Rich., Cypripedium calceolus L., Epipactis atrorubens (Hoffm.) Schult., E. helleborine (L.) Crantz, Lilium martagon L., Listera ovata (L.) R. Br., Neottia nidus-avis (L.) Rich., Platanthera bifolia (L.) Rich., P. chlorantha (Cust.) Reichenb., Galanthus nivalis L., Carex umbrosa Host) and 28 locally rare species preserved within the Volyn, Rivne and Lviv regions. The major threats for these species were indicated. Four rare associations, according to the Green Data Book of Ukraine, were studied in the Volyn Upland (Carpineto (betuli)–Quercetum (roboris) hederosum (helicis), Carpineto (betuli)–Fraxineto (excelsioris)–Quercetum (roboris) alliosum (ursini), Tilieto (cordatae)–Carpineto (betuli)–Quercetum (roboris) alliosum (ursini) and Pinetum (sylvestris) caricosum (humilis)) and their structure, main features and status were characterized in detail. The importance of further research, and the development of recommendations for the conservation and continued preservation of these forest ecosystems of the Volyn Upland was highlighted.

Therapeutic plants found in agrocenoses of the middle Vistula River Valley mesoregion Studies on the segetal flora of the Middle Vistula River Valley mesoregion were carried out between 2003 and 2006 in cereal and potato crops and in stubble fields (117 localities). A total of 184 medicinal vascular plant species were noted in the studied agrocenoses. Native plants (68%) dominated over species brought to Poland (32%). Hemicryptophytes (83 spp.), therophytes (74 spp.) and geophytes (26 spp.) were the most numerous groups of life forms. Perennials (55%) prevailed over short-lived plants (45%). Very rare and rare species (61%) built up the most numerous group of species. Their populations usually consisted of single specimens. Only a few of the medicinal plant species occured as larger populations. They were Aphanes arvensis, Stellaria media and Galium aparine in cereals, Equisetum arvense, Stellaria media, Chenopodium album, Elymus repens, Plantago major, Polygonum amphibium, Mentha arvensis, Plantago intermedia, Polygonum hydropiper and Gypsophila muralis in stubble fields, as well as Stellaria media in potato cultivations.

Different Levels

Nowadays, bioecological characteristics of species are the basis for flora and vegetation studying on the different levels. Bioecological characteristics of species is required in process of flora studying on the different levels such as biotopes or phytocenoses, floras of particular areas (floras of ecologically homogeneous habitats), and floras of certain territories. Ramensky scale is the one of first detailed ecological scales on plant species ordination in relation to various environmental factors; it developed in 1938 (Ramensky, 1971). A little later (1941), Pogrebnyak’s scale of forest stands was proposed. Ellenberg’s system developed in 1950 (Ellenberg, 1979) and Tsyganov’s system (Tsyganov, 1975) are best known as the systems of ecological scales on vascular plant species; these systems represent of habitat detection by ecotopic ecomorphs of plant species (phytoindication). Basically, the system proposed by Alexander Lyutsianovich Belgard was the one of first system of plant species that identiified ectomorphs in relation to environmental factors. As early as 1950, Belgard developed the tabulated system of ecomorphs using the Latin ecomorphs abbreviation; he also used the terminology proposed in the late 19th century by Dekandol (1956) and Warming (1903), as well as terminology of other authors. The article analyzes the features of Belgard’s system of ecomorphs on vascular plants. It has certain significance and advantages over other systems of ecomorphs. The use of abbreviated Latin names of ecomorphs in tabular form enables the use shortened form of ones. In the working scheme of Belgard’s system of ecomorphs relation of species to environmental factors are represented in the abbreviated Latin alphabetic version (Belgard, 1950). Combined into table, the ecomorphic analysis of plant species within association (ecological certification of species), biotope or area site (water area) gives an explicit pattern on ecological structure of flora within surveyed community, biotope or landscape, and on environmental conditions. Development and application by Belgrard the cenomorphs as «species’ adaptation to phytocenosis as a whole» were completely new in the development of systems of ecomorphs and, in this connection, different coenomorphs were distinguished. Like any concept, the system of ecomorphs by Belgard has the possibility and necessity to be developed and added. Long-time researches and analysis of literature sources allow to propose a new coenomorph in the context of Belgard’s system of ecomorphs development: silvomargoant (species of forest margin, from the Latin words margo – edge, boundary (Dvoretsky, 1976), margo – margin, ad margins silvarum – along the deciduous forest margins). As an example of ecomorphic characterization of species according to the system of ecomorphs by Belgard (when the abbreviated Latin ecomorph names are used in tabular form and the proposed cenomorph is used), it was given the part of the table on vascular plants ecomorphs in the National Nature Park «Orelsky» (Baranovsky et al). The Belgard’s system of ecomorphs is particularly convenient and can be successfully applied to data processing in the ecological analysis of the flora on wide areas with significant species richness, and the proposed ecomorph will be another necessary element in the Belgard’s system of ecomorphs.

Abstract Background Biodiversity supports multiple ecosystem services, whereas species loss endangers the provision of many services and affects ecosystem resilience and resistance capacity. The increase of remote sensing techniques allows to estimate biodiversity and ecosystem services supply at the landscape level in areas with low available data (e.g. Southern Patagonia). This paper evaluates the potential biodiversity and how it links with ecosystem services, based on vascular plant species across eight ecological areas. We also evaluated the habitat plant requirements and their relation with natural gradients. A total of 977 plots were used to develop habitat suitability maps based on an environmental niche factor analysis of 15 more important indicator species for each ecological area (n = 53 species) using 40 explanatory variables. Finally, these maps were combined into a single potential biodiversity map, which was linked with environmental variables and ecosystem services supply. For comparisons, data were extracted and compared through analyses of variance. Results The plant habitat requirements varied greatly among the different ecological areas, and it was possible to define groups according to its specialization and marginality indexes. The potential biodiversity map allowed us to detect coldspots in the western mountains and hotspots in southern and eastern areas. Higher biodiversity was associated to higher temperatures and normalized difference vegetation index, while lower biodiversity was related to elevation and rainfall. Potential biodiversity was closely associated with supporting and provisioning ecosystem services in shrublands and grasslands in the humid steppe, while the lowest values were related to cultural ecosystem services in Nothofagus forests. Conclusions The present study showed that plant species present remarkable differences in spatial distributions and ecological requirements, being a useful proxy for potential biodiversity modelling. Potential biodiversity values change across ecological areas allowing to identify hotspots and coldspots, a useful tool for landscape management and conservation strategies. In addition, links with ecosystem services detect potential synergies and trade-offs, where areas with the lowest potential biodiversity are related to cultural ecosystem services (e.g. aesthetic values) and areas with the greatest potential biodiversity showed threats related to productive activities (e.g. livestock).
