Research was carried out improve efficiency of thematic mapping based on the recognition of plant communities in the subzone of dark coniferous forests for South of Sakhalin on multi-time satellite images of average resolution Landsat 8. We used reference samples of sites where geobotanical studies were conducted, for improve the quality of recognition during automated decryption. Experiments were conducted decode vegetation on singlechannel, synthesized multi-zone images obtained in different seasons of year. Spectral characteristics allow us identify plant communities in images based on morphological and physiological properties of various plants, which were quantified by reflection of vegetation in the spring image, and an integral indicator of photosynthetic activity of vegetation, which was evaluated by NDVI index calculated from spring and autumn images. Conceptual and methodological aspects of direct expert interpretation of vegetation from Landsat images by classification methods using ESRI ArcGIS raster algebra tools are considered. On example of study of vegetation communities of subzone of dark-coniferous forests of the South of Sakhalin with sufficient level of reliability, dark-coniferous forests, stone birch forest, cedar elfin formation, valley forests, thickets of Kuril bamboo, as well as residential zones, agricultural lands, areas devoid of vegetation as result of gravitational slope processes, wetlands, windfalls and man-made wasteland were identified. Decoding of vegetation cover from Landsat images showed that use of seasonal time series can significantly increase the reliability of the interpretation of most species of plant communities for the South of island. The research area is characterized by significant difference in altitude from 0 to 1100 m, as a result presence of high-altitude zone in the vegetation cover, which must be taken into account when decoding. Mapping is completed by performing automatic vectorization of raster layers and further generalization of vector polygons in accordance with selected map scale.

The article is dedicated to the 35th anniversary of publication of the first edition of the Green Data Book of Ukraine. This publication was a notable event in the 100-year history of research activity in the M.G. Kholodny Institute of Botany of the National Academy of Sciences of Ukraine, where the scientific and methodological principles of the Green Data Books originated. The outcomes of the history and preconditions for development of a concept of the phytocenodiversity conservation are summarized. Problematic and disputable issues of the Green Data Book are discussed and some future tasks are outlined. Methodological approaches to conservation of natural units and areas are analyzed. It is emphasized that modern methods of biodiversity conservation are based on populational and ecosystemic approaches, while the main mode of conservation of plants is based on conservation of plant communities, which form a phytocenotic matrix for plant cenopopulations. Implementation of scientific principles of the Green Data Book of Ukraine in legislation and regulatory documents of Ukraine. A critical analysis of syntaxonomy of the protected plant communities in Ukraine is provided; 983 associations of 104 formations will form the basis for a new edition of the Green Data Book of Ukraine. The importance of wide public awareness among the general public, public organizations, and international bodies regarding the Green Data Book of Ukraine is emphasized.

AbstractAnthropogenic (or human-caused) wildfire is an increasingly important driver of ecological change on Pacific islands including southeastern Polynesia, but fire ecology studies are almost completely absent for this region. Where observations do exist, they mostly represent descriptions of fire effects on plant communities before the introduction of invasive species in the modern era. Understanding the effects of wildfire in southeastern Polynesian island vegetation communities can elucidate which species may become problematic invasives with continued wildfire activity. We investigate the effects of wildfire on vegetation in three low-elevation sites (45-379 m) on the island of Mo’orea in the Society Islands, French Polynesia, which are already heavily impacted by past human land use and invasive exotic plants, but retain some native flora. In six study areas (3 burned and 3 unburned comparisons), we placed 30 transects across sites and collected species and abundance information at 390 points. We analyzed each local community of plants in three categories: natives, those introduced by Polynesians before European contact (1767 C.E.), and those introduced since European contact. Burned areas had the same or lower mean species richness than paired comparison sites. Although wildfire did not affect the proportions of native and introduced species, it may increase the abundance of introduced species on some sites. Non-metric multidimensional scaling indicates that (not recently modified) comparison plant communities are more distinct from one another than are those on burned sites. We discuss conservation concerns for particular native plants absent from burned sites, as well as invasive species (including Lantana camara and Paraserianthes falcataria) that may be promoted by fire in the Pacific.

A geobotanical survey of rich fens on the left-bank terraces of the Em-Egan River, the right tributary of the Malaya Sosva River in the southern part of the nature reserve “Malaya Sosva” (61.79° - 62.05° N, 64.06° - 64.55° E). 179 species have been identified, including 84 species of higher vascular plants, 69 species of mosses and 26 types of liverworts. Of these, 11 species are included in the Red Data Book of the Khanty-Mansi Autonomous District, including 9 species of higher vascular plants and 2 species of mosses: Baeothryon alpinum, Cardamine nymanii, Dactylorhiza traunsteineri, D. incarnata, Hammarbya paludosa, Huperzia selago, Saxifraga hirculus, Thelypteris palustris, Triglochin palustre, Meesia triquetra, Paludella squarrosa. Three more species – Corallorrhiza trifida, Calliergon richardsonii, Meesia uliginosa are included in the list of species whose condition in the natural environment requires special attention. In addition, such rare species as Eriophorum brachyantherum, Stellaria crassifolia, Bistorta major, rare species of mosses such as Bryum bimum, Calliergonella cuspidata, Campylium pretense, Hamatocaulis vernicosus, Scorpidium cossonii, Tomentypnum nitens are listed in the mire plant communities. On the basis of the ecological-floral approach of the J. Brown-Blanke school, 8 associations, 6 subassociations and 3 communities from 5 unions, 3 orders and 3 classes of vegetation were allocated in the vegetation cover of rich fens. The belonging of one more vegetation community type of the Bistorta major–Sphagnum fuscum dwarf birch community with the sparse fir (Picea obovata) to the class and the order is not established. The highest phytocenotic diversity and the highest concentration of rare and protected species are found in communities of the order Sphagno warnstorfii-Tomentypneetalia. Phytocenotic association and frequency of occurrence of rare species in different types of plant communities are established.

Successional Development

Little is known about the importance of initial colonization in the successional development of restored wetlands. We compared plant communities of two lightly planted restorations (water levels restored + planted and seeded), three hydrologic restorations (water levels restored), and two undrained sites. Measurements typically used in monitoring (richness, diversity, aboveground biomass) indicated that 2–3 years after restoration, restored wetlands showed only small differences from the plant community structure of undrained wetlands in the saturated zone. In contrast, analysis of vegetation based on species composition indicated differences in vegetation communities among all wetland types. Plant communities of planted restorations and reference sites were dominated by emergent species, while hydrologic restorations had a more variable plant community. These results indicate a small effect of initial planting and seeding at low densities and show that colonization is rapid during early succession of restored marshes. It was not clear whether either restoration method would eventually result in vegetation communities similar to reference sites. These results indicate that current monitoring periods of 3–5 years are insufficient to allow time for an accurate assessment of the successional development in each wetland.Key words: dispersal, germination, monitoring, plant biomass, plant community, wetland.

Flora Diversity

Tropical Afromontane forest has the potential for honey production. The main objective of the study was to identify major bee floras and its diversity in different vegetation communities of Gesha-Sayilem forest. Bee flora data were collected systematically from 90 plots with subplots for shrubs and herbaceous species. In addition, pollen traps having 16% pollen trapping efficiency were fitted at the entrance of beehives for pollen load collection. Shannon-Wiener diversity index; species richness and Shannon’s evenness were employed to determine diversity of bee flora. The result showed that 93 bee plant species belongings to 43 families were identified of which Asteraceae the most abundant family was followed by Lamiaceae, Fabaceae, Acanthaceae and Rubiaceae. The analysis of bee forage diversity using Shannon-Wiener diversity index (H) found in 5 different plant communities showed that plant communities one, two, and three have the highest bee flora diversity 3.2, 3.2, and 3.5, respectively. The dominant bee plants in community one were (Ilex mitis and Syzygium guineens), community two (Pouteria adolfi-friederici and Schefflera abyssinica), Community three (Millettia ferruginea and Sapium ellipticum), community four (Hagenia abyssinica and Dombeya torrida), community five (Schefflera-volkensi and Maesa lanceolata). Sorensen similarity coefficient showed that communities 1, 2, 3, and 5 are more similar to each other while community four is less similar. On the other hand, the beta diversity for communities 1, 2, 3, and 5 were 0.25, 0.27, 0.39, and 0.28 respectively while community four has a higher beta diversity index (0.71) indicating low similarity with the rest of the plant communities. In conclusion community 1, 2 and 3 has a high diversity of bee flora and therefore, integration of these communities with beekeeping is recommended.

Glacier Forefield

Abstract. Current glacier retreat allows vast mountain ranges available for vegetation establishment and growth. Little is known about the effective carbon (C) budget of these new ecosystems and how the presence of different vegetation communities, characterized by their specific physiology and life forms influences C fluxes. In this study, using a comparative analysis of the C fluxes of two contrasting vegetation types, we intend to evaluate if the different physiologies of the main species have an effect on Ecosystem Respiration (Reco), Gross Primary Production (GPP), annual cumulated Net Ecosystem Exchange (NEE), and long-term carbon accumulation in soil. The NEE of two plant communities present on a Little Ice Age moraine in the Matsch glacier forefield (Alps, Italy) was measured over two growing seasons. They are a typical C3 grassland, dominated by Festuca halleri All. and a community dominated by CAM rosettes Sempervivum montanum L. on rocky soils. Using transparent and opaque chambers, we extrapolated the ecophysiological responses to the main environmental drivers and performed the partition of NEE into Reco and GPP. Soil samples were collected from the same site to measure long-term C accumulation in the ecosystem. The two communities showed contrasting GPP but similar Reco patterns and as a result significantly different in NEE. The grassland acted mainly as a carbon sink with a total cumulated value of −46.4 ± 35.5 g C m−2 NEE while the plots dominated by the CAM rosettes acted as a source with 31.9 ± 22.4 g C m−2. In spite of the NEE being different in the two plant communities, soil analysis did not reveal significant differences in carbon accumulation. Grasslands showed 1.76 ± 0.12 kg C m−2, while CAM rosettes showed 2.06 ± 0.23 kg C m−2. This study demonstrates that carbon dynamics of two vegetation communities can be distinct even though the growing environment is similar. The physiological traits of the dominant species determine large differences in the carbon cycle. Therefore, to analyze NEE of any glacier forefield ecosystem, different functional traits of the vegetation communities must be taken into consideration. Moreover, to assess the net ecosystem carbon balance it is necessary to consider the lateral fluxes of carbon via animal consumption, winter respiration, and in a broader temporal perspective, the different stages characterizing the primary succession.

Detailed Survey

In the article, characteristics of development of vegetation communities under conditions of mine rock dumps of the Central Mining and Ore Enrichment Combine or their rocky components (lithoecotopes) were determined, namely only lithophilic vegetation. We сlassified various lithoecotopes and characterized vegetation communities of varying complexity growing on plateau tops, terraces and slopes, depending on specifics of their constituent rocks and typological features.  In accordance with the state of lithoecotopes, including all typological characteristics and the geochemical nature of the rocks, plant lithophilic communities growing on the dumps of the Central Mining and Ore Enrichment Combine, were characterized by significant differences in analytical (floristic and ecomorphic composition, occurrence, layerage, aspect, abundance, cover) and synthetic (similarity, constancy) signs. A detailed survey of the state of plants and their communities within the lithoecotopes has allowed us to establish that their distribution and development have clearly expressed dependence on substrate and relief-exposure,which can be used in phytocoenic and phytocenotic melioration of such technogenic ecotopes. Native overgrowth of all dumps has a shrub-tree forest and grassy pattern in accordance with the typological characteristics and rock composition. In general, taxonomic composition of plant communities growing on the dumps of the Kryvbas central zone is characterised by 153 species belonging to 31 families, of which 66 species are petrophytes, and 18 species are typical only for zone surveyed.

A new locality of Carex bohemica, a rare species listed in the Red Data Book of Ukraine, is reported. The studied population is located in Kyiv Region within the Divychky site UA0000337 of the Emerald Network in Ukraine (Left-Bank Forest-Steppe). The territory housing the population forms a single contour covering two areas of different soil humidity values. On the area of 30 m2, 95 individuals of C. bohemica were discovered. At the time of observation, all individuals were of the generative age. The identified variants of plant communities with participation of C. bohemica belong to the class Phragmito-Magnocaricetea and are similar to the most communities with this species found in Ukraine. As a threat to existence of this population, increasing participation of alien invasive species-transformers and synanthropic species can be considered. Frequent fires occurring during drought periods also pose significant risks to the survival of this population. Further search for new localities of C. bohemica in the areas with suitable habitats is required.
