The International conference “Flora and conservation in the Caucasus: history and current state of knowledge” dedicated to the 130-year anniversary of the Perkalsky Arboretum took place at 22–25 of May 2019 in Pyatigorsk (Stavropol Territory) on the base of the Pyatigorsk Museum of local lore and natural history. The participants were from 11 cities of Russia and 7 Republics of the Caucasus and represented 14 institutions. Proceedings of the conference were published by the beginning of the meeting the book of abstracts includes 49 papers on the study of vascular plants, bryophytes, lichens and fungi, plant communities, as well as the protection of rare and endangered species, unique plant communities, and ecological problems in the Caucasus. The following geobotanical topics were highlighted in 13 papers: forest communities (3 reports), meadow and steppe vegetation (2), xeric open forests (2), communities of ecotone areas (1), structure of populations of rare plant species (3), as well as the history and current status of nature protected areas (2). The great emphasis has been focused on the study of floristic composition and plant populations. Thus, the conference showed that very few studies от vegetation are currently carried out in the Caucasus, and a lot of districts are not affected by the research. The greatest attention is paid to forest vegetation while meadow, steppe, alpine heath and xerophytic communities are studied rather poorly. Besides, there are “white spots” — mire, floodplain and aquatic vegetation. In nowadays, when the anthropogenic impact on the plant cover of the Caucasus is intensively increasing, it is especially important to study natural undisturbed communities preserved in protected natural areas. Another important issue is the conservation of the unique vegetation cover of the whole Caucasus. Thus, the study of vegetation of this region opens a wide field for researchers using various methods of modern plant science.

Arrhenatherion alliance meadows are recognized to be among the best pastures in our country due to high productivity and good nutrition value. The research was conducted in several areas of Mures County. The studied grasslands were classified into two types of Natura 2000 habitats: 6510 Lowland hay meadows (Alopecurus pratensis, Sanguisorba officinalis) and 6520 Mountain hay meadows. The identified phytocoenosis belong to two plant associations: Arrhenatheretum elatioris Br.-Bl. Ex Scherrer 1925 and Poo Trisetetum flavescentis (Knapp 1951) Oberd. 1957. The analysis of data collected in the field reveals that the current state of conservation of the two types of habitat is good and very good. Habitats in a good and very good state of preservation is distinguish by a great floristic composition: approx. 100-150 cormophyte species with good and very good forage value. As habitats are more susceptible to the management applied and any changes to land use can affect habitat quality (eg abandoning  mowing and turning the land into pasture), the ecological functions of this habitat will be satisfied as long as they are mowed after Poaceae species matured.

The study of regional floras is one of the main tasks of floristics, which allows one to make the most complete inventory and analyze the species composition. The analysis results in a reconstructed picture of the vegetation development in the investigated area. Human economic activities in the area have created new habitats for the species whose main distribution range is far beyond boundaries of the area. Therefore, the main objective of the study was to study the flora of the islands in the lower Vyg River. To achieve the goal, the route-reconnaissance method was used. The performed work revealed the constancy of the species composition of the flora of the islands. All in all, 136 species were found on the islands, 50% of which are common in this territory and make up the main core, which is part of the northern taiga flora. The differences between the floristic composition of the islands are due to the current state of the Vyg River, altered by the dam of the hydroelectric power station, and a large anthropogenic pressure associated with the development of tourism in the places of petroglyphs accumulation.

Objectifs : Cette étude vise à caractériser l’état actuel des pâturages herbacés du Centre Secondaire de Multiplication de Bétail de Sayam. Méthodologie et Résultats : Quatre groupements pastoraux ont été identifiés et décrits à partir de 56 relevés linéaires réalisés sur un transect Sud - Nord. Au total 98 espèces herbacées réparties parmi 59 genres et 27 familles botaniques ont été répertoriées. Les genres suivants : Eragrostis, Ipomoea, Aristida, Cenchrus, Indigofera, Digitaria et Brachiaria ont été les mieux représentés. Ils représentent environ 50% du total et renferment l’essentiel des espèces de bonne valeur pastorale. Le recouvrement global, les valeurs pastorales brutes et nettes sont respectivement de 85,5%, 75,05% et 67,56%, celles-ci attestent que le pâturage du centre est de bonne qualité. La productivité globale en phytomasse herbacée a été estimée 2,26 tMS/ha avec une capacité de charge globale de 0,40 UBT/ha/an soit 2,5 ha/UBT/an. L’analyse du spectre fourrager indique que les espèces de bonne valeur pastorale et de faible valeur pastorale dominent le tapis herbacé. La première catégorie domine la zone centrale mieux protégée tandis que la dernière occupe les parties périphériques soumises à une forte exploitation du bétail. Conclusion et application des résultats : Le front de colonisation des espèces faiblement appétées (espèces qui ont IS = 0 ou IS = 1) progresse vers le centre sous l’effet de la forte pression pastorale. D’où l’urgence de clôturer l’ensemble du périmètre du centre afin d’éviter de créer un déséquilibre écologique préjudiciable à la survie de nombreuses espèces inféodées à ces milieux particuliers. Dans les perspectives d’une gestion durable des ressources fourragères des centres secondaire de multiplication de bétail, ce travail fournit des informations scientifiques fiables sur l’état actuel des pâturages herbacés de ce centre.

ABSTRACT Objectives : This study aims to characterize the current state of the herbaceous pastures of the Sayam Secondary Cattle Multiplication Center. Methodology and Results : Four pastoral groups have been identified and described from 56 linear surveys carried out on a South - North transect. A total of 98 herbaceous species distributed among 59 genera and 27 botanical families have been listed. The best represented genera are: Eragrostis, Ipomoea, Aristida, Cenchrus, Indigofera, Digitaria and Brachiaria. They represent about 50% of the total and contain most of the species of good pastoral value. The overall recovery, the gross and net pastoral values are respectively 85.5%, 75.05% and 67.56%, these attest that the pasture of the center is of good quality. The overall productivity of herbaceous phytomass was estimated at 2.26 tMS / ha with an overall carrying capacity of 0.40 TLU / ha / year, ie 2.5 ha / TLU / year. Analysis of the forage spectrum indicates that species of good pastoral value and those of low pastoral value dominate the grass cover. The first category dominates the better protected central zone while the last occupies the peripheral parts subject to heavy livestock exploitation. Conclusion and applicability of results : The colonization front of poorly palatable species is progressing towards the center under the effect of strong pastoral pressure. Hence the urgency to enclose the entire perimeter of the center in order to avoid creating an ecological imbalance detrimental to the survival of many species dependent on these particular miles. With a view to the rehabilitation and sustainable management of these pastoral centers, this study provides additional information on the current state of the herbaceous pastures in this center.

Abstract The aim of the study is to characterise herbaceous vegetation (meadows and ruderal communities) remaining after several decades of protection and compare it to the vegetation of currently managed local sites in the Central Forest Reserve, Tver Oblast, Russia. Cluster analysis of the communities was based on 209 relevés, while their ecological features were analysed using phytoindication assessment. The analyses revealed four types of herbaceous communities: managed mesic meadows, abandoned mesic meadows, tall-herb meadowsweet communities and ruderal tall-herb communities. These four types differ in management, floristic composition and ecological conditions as well as in coenotic and functional group shares (including forbs, graminoids and woody species). The occurrence of these species groups determines the current state of the herbaceous communities. Our study revealed that mesic meadows have retained all the key meadow features for more than 25 years without any management, although their area has shrunk and shares of coenotic and functional groups have changed. The observed herbaceous communities encompass around 40% of the reserve flora including four red list species and 16 alien species.

AbstractPresented survey summarizes the results of the studies published predominantly after 2000, dealing with the plant communities around and above the timberline in (montane) subalpine to alpine (subnival) belt of the Western Carpathians. All of these communities underwent a critical syntaxonomical and nomenclatorical revision, hence the demonstrated overview of high-mountain vegetation of Western Carpathians (mostly from Slovakia, less from Poland border areas) represent the current state of knowledge. The high-altitude vegetation database, which is the part of Slovak National Vegetation Database, SNVD (http://ibot.sav.sk/cdf/index.html), incorporated 8,160 published relevés on 15 May 2007 (of the total of 30,469 published relevés in the SNVD). Concerning the unpublished relevés, the individual authors have provided more than 18,400 of them to be stored in SNVD; 2,301 of all unpublished relevés could be assigned to high-altitude vegetation. Mountain and alpine vegetation is in SNVD presented by 15 classes; the most frequent class is Mulgedio-Aconitetea. With its quantity and also the quality of relevés, the high-altitude database, as well as the whole SNVD, represents the unique database within Slovakia, which provides information not only about the locality, floristic composition and variability of individual vegetation types, but also about several environmental variables such as inclination, aspect, geology or soil type, characteristic for individual relevés. Together with other Central European databases, SNVD takes up the leading position in Europe.

The aim of the study to analyze the development and modern state of the gardens and parks of the former iron mines at Kryvorizhzhya. During 2013-2017, nine objects of landscape and park at Kryvorizhzhya were explored. Among them were: 1) seven operating parks («Ternivskyi», «Shakhtarskyi», «Zatyshnyi», Suvorov sports park, park near the Palace of Culture of mine «Rodina», «Saksahanskyi», «Rudanivskyi»), one abandonment park in the exclusion zone (Park of mine «Hvardiiska»), one garden of hotel «Park House» (private property). Initially, a historical description of the above objects of landscaping, as well as their structural and functional organization was presented. In the future, in the field conditions, by the route method, the present state of the gardens and parks was investigated and the general level of development of their shoots and shrubs was determined. System creation of gardens and parks on the territory of former iron mines of Kryvorizhzhya began in the 30's of the 20th century, and became massive in the 50's and 60's of the twentieth century. After 80 years of the 20th century there was a change in their owners, a decrease in their social status and the cessation of necessary expenses for their maintenance. At the beginning of the XXI century, among the gardens and parks of the former iron mines of Kryvorizhzhya, in the best condition is the Garden of the Hotel «Park House», which incorporates modern garden and park technology. Now the parks «Shakhtarskyi» and «Saksahanskyi» have the official status – the district parks of the city. The park «Ternivskyi» has the informal status of the main park of the neighborhood. That's why all these parks are actively used, and their territory is relatively well-groomed. Simultaneously others Parks («Zatyshnyi», near the Palace of Culture of mine «Rodina» and «Rudanivskyi») turned out to be less popular for visitors and less for owners. Therefore, their area and plantations - only partially well-groomed. Suvorov sports park, as well as Park of mine «Hvardiiska» are most de-structured. Therefore, their territory is practically unhealthy and the species composition of trees and shrubs degrades. In general, the current state of the gardens and parks of the former iron mines of Kryvorizhzhya depends on «social demand», the degree of their remoteness from residential areas and containment technologies. The obtained results can be used during the development and substantiation of the system of measures for optimization of existing and designing of new garden and park plantings in industrial regions. In further research it is expedient to analyze the environmental conditions of the gardens and parks of the former iron mines of Kryvorizhzhya, as well as the floristic composition and the condition of woody-shrub species. In addition, it makes sense to expand the list of these mines and explore the gardens and parks of inactive mines to them May 1 and Ingulets.
