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 formation of the modern flora and fauna of Kamchatka, paleogeography, natural ecosystems are considered. The biological diversity of the most important groups of biota is analyzed: vascular plants, mollusks, echinoderms, crustaceans, insects, fish, birds, mammals. The most prominent representatives, including economically significant ones, are highlighted. Brief information on paleodendroflora is given, a brief analysis of currently flourishing vascular plants is given. The fossil forms of extinct and currently living animals inhabiting the natural ecosystems of Kamchatka are described. A polytomic analysis of the biota was performed and its functional structure was established. For researchers in the field of ecology and nature protection, teachers and students of relevant academic disciplines, as well as for a wide range of readers in order to learn about the nature of the region and environmental education.

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.

ABSTRACTFew scientific observations have been made at Middle and Stoltenhoff Islands, small (ca 10 ha) islands off the north coast of Nightingale Island, Tristan da Cunha. We recorded vascular plants and numbers of breeding birds on both islands in December 2009. Despite being smaller and more isolated than Middle Island, Stoltenhoff supported more species of plants, including Cotula moseleyi, previously thought to be endemic to Nightingale Island. Only one alien plant was found, Sonchus oleraceus. Populations of two albatross species apparently have decreased by at least half over the last 40 years, presumably due to mortality at sea. Stoltenhoff probably has the least disturbed habitat in the Tristan group, and strict controls are needed to prevent accidental introductions by anyone going ashore.
