Ecological-phytocoenotic confinement of Platanthera bifolia in conditions of middle taiga subzone of Kirov Region was investigated. Studied coenopopulations are restricted mostly to spruce-birch, pine and rarely to spruce phytocoenoses. Herbaceous-shrub cover includes 78 species of vascular plants with dominance of Maianthemum bifolium L., Vaccinium myrtillus L. , Vaccinium vitis-idaea L., Hieracium pilosella L., Equisetum sylvaticum L. , Pyrola rotundifolia L. , Linnaea borealis L. , Trientalis europaea L. , etc . Populations age spectres are in most cases normal and incomplete. Ontogenesis of P. bifolia has pregenerative and generative periods as well as juvenile, immature, virginile and generative age stages. Ecological positions of the species within Bylina Nature Reserve are given by Tsyganov scales. It was shown that P. bifolia is a mesobiont species. Maximum potential of P. bifolia is marked on soil acidity scale (11,54%) and illumination scale (11,51%). Estimation of habitat ecological conditions for P. bifolia was accomplished with Ellenberg scales. It was defined that P. bifolia is characterised by significant ecological amplitude. It is a subcontinental, semi-shade species which prefers semi-wet soils with moderate acidity and moderate nutritients richness. According to hemeroby parameters, P. bifolia can be considered a species that survives insignificant and moderate anthropogenic influence in the studied area.

The aim of the work is to supplement and clarify the annotated list of vascular plants of “Castel” nature reserve on the Southern coast of the Crimea. Methods. The work is based on the results of long standing field research, which was carried out by the traditional route-reconnaissance method, analysis of YALT herbarium materials and data from literary and Internet sources. Arealogical and biomorphological characteristics of species are given according to "Biological Flora of the Crimea" by V.N. Golubev, biotope coding according to EUNIS habitat classification. The nomenclature of taxa corresponds to the " Spontaneuos flora of the Crimean peninsula" by A.V. Yena and to international databases Euro+Med PlantBase, The Plant List, Catalog of Life. Results. An additional annotated list of vascular plants of “Castel” nature reserve has been compiled, including 152 species, subspecies and cultivars from 97 genera of 38 families, of which 53 genera and 11 families have also not been cited for this territory before. Arealogical, biomorphological, biotopic and sozological characteristics of the taxa are given. As a result of a critical analysis of the list previously published by E.S. Krainyuk, four species were redefined, two species were proposed to be excluded from the flora of the specially protected natural area, several taxa are considered doubtful. Conclusions. The list of vascular plant taxa in “Castel” nature reserve has been supplemented with 11 families, 53 genera, and 152 species, subspecies, and cultivars; several species from the previously compiled list have been proposed to be excluded or considered doubtful. Thus, the flora of the protected area includes at least 425 species from 68 families. For the first time, the biotopic characteristic of the flora of the reserve was established.

Classification scheme of rare habitats of Europe according to Bern Convention and Habitat Directive of EU was presented for the territory of Drevlianskyi nature reserve. It was shown significant habitat’s diversity of nature reserve from all main types of habitats — water (permanent and temporary lakes (waterbodies), watercources, reedbeds habitats), bog (eutrophic and mesotrophic mires), grassland (dry, mesic and wet grassland, floodplain and fen scrub, heaths), forest (leaved and conifer forests (woodland), rock (rocks and talus of silicate rocks). According to the results of field research, the territory of the reserve represented by 30 habitats (1 — ІІ leaves, 4 — ІІІ leaves, 25 — ІV leaves). It is established that the most common habitat 91T0 (Central European lichen Scots pine forests), which represented by 153 localities in A1C (dry pine forest) on an area of 421.5 ha. It was made a conclusion that the role of rare habitats in nature reserve Drevlianskyi is determinant for conservation of rare species of vascular plants that are protected by the Bern Convention, European Red List and included to the Red Book of Ukraine. The results of the analysis of the role of rare biotopes of Europe in the conservation of species of flora of different protection status on the territory of Drevlianskyi nature reserve show that most of the rare plant species of reserve listed in Resolution № 6 of the Bern Convention (Annex I), revised in 2011, are present in its rare settlements. The role of rare habitats of Drevlianskyi nature reserve in the conservation of rare species of flora is decisive — of the 29 species of plants of supranational and national levels of protection in rare habitats there are 24 species or 82.8% of their total number.

The Kitulo Plateau of southern Tanzania is a lava plateau covering 273 sq km at an altitude of over 2500 m. The vegetation is predominately grassland with more than 350 taxa of vascular plants, of which nearly 5 per cent are of restricted distribution. Although the plateau is extensive, much of it is now cultivated. Digital analysis of satellite images showed that at least 24 per cent of the plateau was bare soil, modified grassland or cultivation between 1973 and 1989. The botanical importance of the plateau and increase in cultivation make a strong case for the establishment of a nature reserve to protect its rare and threatened plants.

We have developed a system of plant functional groups for modeling dynamics of forest ground vegetation. Ecological and coenotic traits of species together with species life form and biomass values were used to classify species into the functional groups. Ground vegetation patches dominated by species of different plant functional groups were distinguished in the forest floor. We have characterized biomass of these patches by applying of statistical analysis of published data and results of our own field investigations combined into the database "Biomass". Biomass of vascular plants and bryophytes quite well differs between the patches. Variations of above and below ground biomass of vascular plants are minimal within the types of forest floor patches as compared to their variations within the plant functional groups and forest types. Database "Elements" on element concentrations of herbaceous species and cryptogams was also developed on the basis of results of field investigations in the North and the Middle Taiga. The functional groups of species well differ on the concentration of elements in plants forming a group. We have proposed a conceptual model of dynamics of ground forest vegetation; a model compatible with the individual-based EFIMOD model of forest growth and elements cycles in forest ecosystems. Spatial unit of the ground vegetation model is the same as spatial unit of the EFIMOD (0.5×0.5 м); it is a patch of the forest floor dominated by species from one or more functional groups.

Abstract The article is devoted to the research results concerning the flora of vascular plants of the Makarovsky Nature Reserve situated in the middle part of Sakhalin Island. Nowadays, 407 species of vascular plants have been identified on its territory, and 26.8 % of the total number of taxa known on the island. Among them, 13 species of rare plants included in the Red Data Book of the Sakhalin Region have been identified. The structure of the leading families and genera is indicated, the flora is analyzed by life forms, geographical elements and ecological-cenotic groups.
