Although the publication of the vascular flora of the Caribbean islands of Trinidad and Tobago extended from 1928–1992, it is incomplete with the family Poaceae still outstanding. Many of the early recorded families are in need of extensive revision. Therefore, this checklist is intended to fill these gaps by providing a comprehensive list of the vascular plants for the islands. We compiled the checklist using the results from herbarium records, literature citations, online resources and a Rapid Botanic Survey (RBS) of 240 sample plots across the islands. From the RBS plots 22,500 vascular plant specimens were collected, yielding 1530 species. The herbarium records, literature citations and the RBS plots yielded a total of 3639 species, of which 2407 are indigenous, 1222 are exotic and 108 are endemic or near endemic. The low endemism is attributed to the islands’ close proximity to and recent separation from the South American continent. A total of 262 species of grasses (Poaceae) is published here for the first time along with the results from the RBS plots. Our annotated checklist further presents two types of conservation rating: the International Union for the Conservation of Nature Red List Categories and a global Star rating system. Based on the clustering of the ‘Star rating’ of each species, plant communities in the following areas: the Heights of Aripo, parts of the Nariva Swamp and the North-west Islands were identified as ‘hot spots’ of high conservation value which should continue to, or receive greater protection in the National Parks and Protected Areas system established in Trinidad and Tobago.

Vera Antonovna Martynenko (17.02.1936–06.01.2018) — famous specialist in the field of studying vascular plant flora and vegetation of the Far North, the Honored worker of the Komi Republic (2006), The Komi Republic State Scientific Award winner (2000). She was born in the town Likhoslavl of the Kali­nin (Tver) region. In 1959, Vera Antonovna graduated from the faculty of soil and biology of the Leningrad State University and then moved to the Komi Branch of USSR Academy of Science (Syktyvkar). From 1969 to 1973 she passed correspondence postgraduate courses of the Komi Branch of USSR Academy of ­Science. In 1974, she received the degree of candidate of biology (PhD) by the theme «Comparative analysis of the boreal flora at the Northeast European USSR» in the Botanical Institute (St. Petersburg). In 1996, Vera Antonovna received the degree of doctor of biology in the Institute of plant and animal ecology (Ekaterinburg) «Flora of the northern and mid subzones of the taiga of the European North-East». The study and conservation of species and coenotical diversity of the plant world, namely the vascular plants flora of the Komi Republic and revealing its transformation under the anthropogenic influence, was in the field of V. A. Martynenko’ scientific interests. She made great contribution to the study of the Komi Republic meadow flora and the pool of medi­cinal plants. She performed inventorying and mapping the meadows of several agricultural enterprises of the Republic, revealed the species composition and places for harvesting medicinal plants and studied their productivity in the natural flora of the boreal zone. The results of her long-term studies were used for making the NPA system and the Red Book of the Komi Republic (1998 and 2009). Vera Antonovna participated in the research of the influence of placer gold mining and oil development on the natural ecosystems of the North, and developed the method of long-term monitoring of plant cover. Results of these works are of high practical value. V. A. Martynenko is an author and coauthor of more than 130 scientific publications. The most important jnes are «Flora of Northeast European USSR» (1974, 1976, and 1977), «Floristic composition of fodder lands of the Northeast Europe» (1989), «The forests of the Komi Republic» (1999), «Forestry of forest resources of the Komi Republic» (2000), «The list of flora of the Yugyd va national park» (2003), «The guide for vascular plants of the Syktyvkar and its vicinities» (2005), «Vascular plants of the Komi Republic» (2008), and «Resources of the natural flora of the Komi Republic» (2014). She also was an author of «Encyclopedia of the Komi Republic» (1997, 1999, and 2000), «Historical and cultural atlas of the Komi Republic» (1997), «Atlas of the Komi Republic» (2001, 2011). V. A. Martynenko made a great contribution to the development of the botanical investigations in the North. Since 1982, during more than 10 years, she was the head of the Department of the Institute of Biology. Three Ph. D. theses have been completed under her leadership. Many years, she worked actively in the Dissertation Council of the Institute of biology Komi Scientific Centre UrB RAS.  The death of Vera Antonovna Martynenko is a heavy and irretrievable loss for the staff of the Institute of Biology. The memory of Vera Antonovna will live in her numerous scientific works, the hearts of students and colleagues.

Species diversity of plants was recorded in 1992 and 1993 at seven stations of the “Evolution Canyon” microsite. Higher solar radiation on the South-Facing Slope (SFS) causes warm, xeric savannoid formation versus temperate, cool, mesic, dense maquis on the North-Facing Slope (NFS), and riverine, segetal plant formations on the Valley Bottom (VB). In an area of 7000 m2, we recorded 320 vascular plant species in 217 genera and 59 families. Plant cover varied from 35% (SFS) to 150% (NFS). Annuals predominated among all life forms (61.3% of all species). SFS and NFS varied in species content, sharing only 31–18% of species. Phytogeographical types varied among the two slopes and valley bottom. Inter-and intraslope species composition varied drastically due to differential microclimatic stresses, thereby demonstrating at a microscale natural selection in action.

The present edition of the annotated checklist is a comprehensive catalogue of all vascular plant taxa: native and alien that occur in Iceland. The checklist features nearly 2500 taxa names, including ca. 1000 accepted names and more than 1400 synonyms and encompasses, apart from the updated list of native taxa, a complete and revised list of non-native plants (both naturalized and casual) as well as a number of more important cultivated species. According to the checklist, there are 426 native taxa in the Icelandic flora. Ten taxa have been classified as doubtfully native, ten taxa have been classified as non-native of unknown age and 19 taxa qualified as archaeophytes. There are at least 65 non-native taxa naturalized in the Icelandic flora. In total, there are 530 taxa able to form self-sustaining populations in Iceland. Apart from the main core, 282 taxa have been registered as casual aliens (not able to form self-sustaining populations). One species – Primula egaliksensis, has been classified as extinct. The list encompasses also 150 taxa excluded from the Icelandic flora, with brief explanations of the reasons that lead to the exclusion.

The proposed Highveld National Park (HNP) is an area of high conservation value in South Africa, covering approximately 0.03% of the endangered Grassland Biome. The park is situated immediately adjacent to the town of Potchefstroom in the North-West Province. The objective of this study was to identify, classify, describe and map the plant communities in this park. Vegetation sampling was done by means of the Braun-Blanquet method and a total of 88 stratified random relevés were sampled. A numerical classification technique (TWINSPAN) was used and the results were refined by Braun-Blanquet procedures. The final results of the classification procedure were presented in the form of phytosociological tables and, thereafter, nine plant communities were described and mapped. A detrended correspondence analysis confirmed the presence of three structural vegetation units, namely woodland, shrubland and grassland. Differences in floristic composition in the three vegetation units were found to be influenced by environmental factors, such as surface rockiness and altitude. Incidences of harvesting trees for fuel, uncontrolled fires and overgrazing were found to have a significant effect on floristic and structural composition in the HNP. The ecological interpretation derived from this study can therefore be used as a tool for environmental planning and management of this grassland area.Conservation implications: Grasslands are amongst the most threatened and least conserved vegetation biomes in South Africa, with less than 1.3% currently being conserved. The HNP has significant value for biodiversity conservation and the protection of this area will contribute to the preservation of the highly threatened Highveld vegetation types.

According to the results of the ecological-geographical analysis, the aboriginal fraction of the vascular plant flora of Kuznetsov Mountain (Samara Region) is presented Eurasian (74,8% of species from the composition of the aboriginal fraction), Pluriregional (14,5%) and European (10,7%) geographical elements. The largest number of species have Eurasian (32,2%), European-West Asian (14,4%), Holarctic (12,1%), Euro-Siberian (10,3%), European (8,8%) and European-West Siberian (8,4%) longitude areal types. The latitudinal component of the areal is dominated by plurizonal (36,9% of the natural fraction of the flora), boreal-nemoral (21,5%), forest-steppe (15,4%) and nemoral (12,1%) plant species. The adventive fraction of flora is mainly formed by species of the Mediterranean, the North American (28,3% each of the composition of the adventive fraction) and the Iranian-Turanian (24,5%) origin. The current geographical distribution of a significant part of the adventitious species is associated with Holarctic (30,2%), Eurasian (22,6%), Hemicosmopolitan (17,0%) and European-West Asian (11,3%) areals. The endemic species ( Crataegus volgensis Pojark.) and 8 relict species [ Anemone altaica Fisch. ex C.A. Mey., Bupleurum aureum (Hoffm.) Fisch. ex Hoffm., Laser trilobum (L.) Borkh., Pulmonaria mollis Wulfen ex Hornem., Geranium robertianum L., Caragana frutex (L.) C. Koch, Aconitum septentrionale Koelle, Corydalis solida (L.) Clairv.] have been identified in the flora of the vascular plants of Mountain Kuznetsov. The boundaries of the areals of 7 flora species [ Matteuccia struthiopteris (L.) Todaro, Athyrium filix-femina (L.) Roth, Aconitum septentrionale Koelle, Crataegus volgensis Pojark., Bupleurum aureum (Hoffm.) Fisch. ex Hoffm., Campanula latifolia L., Anemone altaica Fisch. ex C.A. Mey.], represented on Mountain Kuznetsov, pass through the territory of the Samara Region.

This study provides a first checklist of the native vascular plant taxa of Djurdjura National Park, based on collections and field visits (2011–2015), with an analysis of its composition and species diversity. The results of floristic analysis outlines the main characteristics of the flora of Djurdjura National Park. It hosts a remarkable species diversity of 757 plant taxa (including 659 species, 95 subspecies, 2 varieties, and 1 forma) belonging to 381 genera in 88 families. Despite covering ca. 0.008% of the total area of Algeria, this national park protects about 17% of the vascular plants of the country. The most represented families are Asteraceae, Fabaceae, Poaceae, Lamiaceae, Apiaceae, Caryophyllaceae, Rosaceae, and Brassicaceae, while the most represented genera are Trifolium (with 15 taxa) and Silene (12). Hemicryptophytes (37.25%) and therophytes (30%) are the most represented life forms among the local flora, a pattern typical of mountainous areas. Mediterranean taxa comprise 64.6%, followed by North African taxa (14%), European (7.53%), and widely distributed taxa (13.87%), which reveals the Mediterranean character of the mountain’s flora. The endemic flora of Djurdjura National Park contains 106 taxa (14%), of which 20 are endemic to Algeria. In addition, six are exclusive and range-restricted to the Djurdjura National Park. Hence, we emphasized a large number of priority taxa (30) of high conservation value. The presence of exclusive endemics, and threatened species, along with high floristic diversity, strengthen the importance of plant conservation in the studied area.

Following the targeted expansion of the area of distribution for the muskox (Ovibos moschantus Zimm.) in Russia, expert assessment of animal feed resources was carried out on Zavyalov Island, located in the Sea of Okhotsk. The island’s area is 116.7 sq. km, with 45.5% (53.1 sq. km.) unsuitable for grazing by muskoxen. The rest of the island is potentially pasture-friendly. A synopsis of the vegetation on Zavyalov Island (Zavyalov Island, 2012) had previously been made by the researchers from the Institute for Biological Problems of the North (IBPN FEB RAS), which was adopted by us as a basis for the reconnaissance survey of the area. Guided by the published data and our own observations on the grazing habits of ungulates, we compiled a list of vascular plant species from the basic potential forage ration of the muskox and a list of possible substitutive forage species on Zavyalov Island. Out of the Island’s total vegetation, 154 species can be regarded as edible or potentially suitable forage plants for the muskox, including 45 species known from published sources as already present in this animal’s feeding ration. Of these, only 26 species are abundant and frequent enough to be considered as having significant feeding potential for the muskox, while the rest are rare or produce too little biomass. Having been placed in the new environment, muskoxen are expected to safely switch to substitute forage plants, represented here by 109 species. In total, 44 species can be recognized as the most promising, considering their abundance and frequency of occurrence. Such set of vascular plants is likely to be sufficient for the adaptation of a limited number of muskoxen in the area. According to prior estimates based on the area of suitable pastures, Zavyalov Island will be able to provide up to 25 individual animals with enough forage. It is recommended to supply additional feed, such as hay and branches, during the initial phase of their adaptation, and later launch scientific monitoring over the animals as they get used to the forage potential of Zavyalov Island.
