Изучение разнообразия охраняемой флоры в заповеднике Нам Донг (северный Вьетнам) проведено в рамках флористических исследований территории в 2015–2019 гг. Исследование проводилось на семи профилях, заложенных от самых низких высот над уровнем моря до высшей точки изучаемой территории, с таким расчетом, чтобы максимально охватить возможное число местообитаний на склонах разной экспозиции. Флористические исследования позволили уточнить состав редких и охраняемых видов растений территории, имеющих международный или национальный природоохранный статус. К таким растениям в заповеднике относятся 88 видов (6,7% от всей местной флоры), принадлежащих к 51 семейству (28,3% от 180 семейств флоры). Охраняемые виды относятся к трем отделам сосудистых растений: Polypodiophyta – 5 видов (5,7%), Pinophyta – 10 (11,4%), Magnoliophyta – 73 (83,0%). Из них 57 видов занесены в список МСОП (IUCN), в т.ч. EN (исчезающие) – 7 (8,0%), VU (уязвимые) – 11 (12,5%), NT (находящиеся в состоянии, близком к угрожаемому) – 7 (8,0%), LC (вызывающие наименьшие опасения) – 32 (36,4%), DD (требующие дополнительных исследований) – 2 (2,3%); 43 вида охраняется в соответствии с Красной книгой Вьетнама (2007), в том числе EN – 11 (12,5%), VU – 32 (36,4%); 18 видов – в соответствии с Постановлением об охране редких и ценных видов флоры и фауны Вьетнама (2006). 37 видов, входящих в список МСОП, не охраняются во Вьетнаме. Однако 10 видов из этого списка со статусом EN, VU, NT могут составить ресурсную базу для реинтродукции их на территории, где виды исчезли или находятся на стадии полного вымирания. The study of the diversity of protected flora in the Nam Dong Nature Reserve (North Vietnam) was carried out as part of the study of the territory's flora in 2015–2019. The study was carried out on 7 profiles, laid down from the lowest heights to the highest point of the studied territory, in such a way that it would cover the maximum possible number of habitats on the slopes of different exposures. Floristic studies have made it possible to clarify the composition of rare and protected plant species of the territory that have international or national conservation status. Such plants in the reserve include 88 species (6.71% of all local flora) belonging to 51 families (28.33% of 180 flora families). Protected species belong to 3 divisions of vascular plants: Polypodiophyta – 5 species (5.68%), Pinophyta – 10 (11.36%), Magnoliophyta – 73 (82.95%). Of these, 57 species are listed in the IUCN (IUCN), including EN (endangered) – 7 (7.95%), VU (vulnerable) – 11 (12.50%), NT (near-threatened) – 7 (7.95%), LC (least concern) – 32 (36.36%), DD (requiring additional research) – 2 (2.27%); 43 species are protected in accordance with the Red Book of Vietnam (2007), including EN – 11 (12.50%), VU – 32 (36.36%); 18 species – in accordance with the Decree on of the Government on management of endangered, precious and rare forest plants and animals (2006). 37 species included in the IUCN list are not protected in Vietnam. However, 10 species from this list with the status EN, VU, NT, can form a resource base for their reintroduction in the territory where the species have disappeared or are at the stage of complete extinction.

Because of preparing new edition of “Krasnoyarsky Region Red book (plants and fungi)”, the change of approaches to formation of specially protected vascular plants list are proposed. The changes of principles for adding species to this list are proposed, as well as offers by including and excluding the species. In particular, conferring conservation status is necessary not only for species at whole, but for separate large populations. The special approaches is necessary for species, hard to definite in nature. Besides, it is necessary to supplement new edition by Appendix “The list of Krasnoyarsky Region plant species needing special attention by their condition in nature”.

The Status

Assessment of plant species in particular rare and endemic is essential for monitoring and conservation planning. I aimed to support conservation activities by addressing knowledge of the status of Aloe dhufarensis Lavranos, one of the endemic plants in the Arabian Peninsula. Information on the status and distribution range of A. dhufarensis in the Arabian Peninsula is almost absent. To Assess A. dhufarensis according to IUCN categories, Extent of Occurrence (EOO) and Area of Occupancy (AOO) were created and measured using ArcMap 10.8. The species is described and illustrated; the distribution of the species was mapped. The evaluation and the conservation status of this plant species are reported according to the context of IUCN Red List guidelines and criteria.

Conservation Assessments

Lack of basic data to assess plant species against IUCN Red List criteria is a major impediment to assigning accurate conservation status throughout large areas of the world. Erroneous assessments will be most prevalent in vast poorly surveyed areas where herbarium collections are sparse. In arid environments, assessments are further confounded by extreme temporal variability and poor understanding of the nature and magnitude of threats. We systematically re-assess the conservation status of an arid-zone flora. The status of all 1781 vascular plant species occurring across 635 300 km2 of inland eastern Australia was initially assessed through herbarium records and expert interviews. This process generated a list of apparently rare and potentially threatened species, which guided a targeted survey program over 4 years. Search effort and key data on populations of candidate species found were recorded and used to assess 91 species against IUCN criteria. One-third of species were widespread and abundant at least in certain seasons, but had been deemed rare due to sparse collections. The conservation status of 20, mostly newly recognised species from restricted habitats, was upgraded and 14 remained listed because of having restricted areas of occupancy. With the exception of 12 artesian spring species, continuing declines were documented for just six species. The criterion that allows for listing of species because of extreme fluctuations (in combination with restricted and fragmented populations) needs to be carefully interpreted in arid zones, where these fluctuations may be apparent rather than real, and may actually confer resilience to grazing for some species. Our approach facilitates robust conservation assessments across vast and poorly known arid regions, distinguishing species that have merely been lost in space and time from those that are at risk of extinction.

Abstract Brazil is signatory of the Global Strategy for Plant Conservation (GSPC), which provides guidelines and directions to existing national policies. This strategy aims to halt the continuing loss of plant diversity through the achievement of 16 outcome-based targets set for 2020. One of these targets (target 7) states that at least 75% of known threatened plant species should be preserved in situ. Here, we assessed the effectiveness of the Brazilian current network of protected areas (PAs) and indigenous lands (ILs) in representing all known threatened plant species. We found that the number of species represented inside PAs and ILs varied according to data type. When using occurrence records, we found that 699 (33%) threatened plant species lie completely outside PAs (and/or ILs) and that 1,405 species (67%) have at least one record inside at least one PA (and/or IL). The number of species unrepresented decreased when we considered polygons of distribution. In this case, only 219 (10%) are supposedly unprotected. Although Brazil is almost reaching GSPC Target 7 in terms of absolute numbers, the government still needs to allocate resources for properly managing and improving the conservation status of its imperiled flora and expand the network of PAs.

The Balkan sub-endemic species Dactylorhiza kalopissii E. Nelson is distributed in Bulgaria, Greece and North Macedonia. It has a local distribution and inhabits alkaline fens, wet meadows, and mountain rivulet banks. This orchid is a globally endangered species, included in Annex IIb of the Council Directive 92/43 EEC. It was first reported for Bulgaria in 1991 and until 2008 it was known only from this single locality in the country. Here we summarize the recent data on the distribution of the species in Bulgaria, the population numbers and their fluctuation in time. During the period 2008 - 2019 the species was found in more than ten localities of six floristic regions. Populations usually number less than 250 individuals. For some of the populations, data from recurrent observations are provided. We discuss the habitats and their management. The negative changes of the habitat quality during the last years for some of the localities are described as well. The species was evaluated as CR B1ab (iii) + 2ab (iii) according to the Red List of Bulgarian vascular plants. We reevaluate the status based on the improved knowledge. The species is still Critically Endangered in Bulgaria, but В2ab (iii, v) status better corresponds with recent data. Five of the known localities fall within the boundaries of Natura 2000 SCIs.

AbstractCinnamomum chago is a woody species of the family Lauraceae endemic to Yunnan province, China, previously known from only one location, and categorized as a Plant Species with Extremely Small Population. We surveyed to determine the distribution and population size of C. chago, characterize its habitat, identify any threats, assess its conservation status, and provide guidelines for its management and conservation. During 2014–2017 we found only 64 mature C. chago, in five locations. These small, fragmented populations occur along Lancang River in Dali Prefecture at altitudes of 2,200–2,400 m. The species' extent of occurrence is c. 923 km2, with an area of occupancy of c. 60 km2. The habitat of the species has been degraded by expansion of pastoral activities and deforestation. We recommend categorization of C. chago as Endangered on the IUCN Red List, prevention of the collection of seeds and wood of the species, protection and monitoring, and ex situ propagation for future reintroductions.

Special Relevance

The value of distinguishing between plant species regarded as ‘native’ and ‘alien’ has special relevance in the island continent of Australia, where European settlement was a springboard for human-assisted plant dispersal. The year of European settlement is proposed here as providing a distinction between a ‘native’ and ‘naturalised’ flora and is applied for the entire Australian flora of vascular plants. Herbarium collections and ecological criteria were employed to determine the status of 168 species of ambiguous origin. The date of 1788 proved to be a relatively straightforward criterion to assign native and naturalised status and the origin of only 27 plant species remains ambiguous. The dispersal of plants between continents is an ongoing process but European settlement of the Australian continent represents a very sharp biogeographic event for the Australian flora and provides a straightforward criterion for determining the ‘naturalised’ species.

AbstractIn 1994 Alan Rabinowitz decried what he regarded as lackadaisical attempts by governments, NGOs and international funding agencies to conserve the Sumatran rhinoceros Dicerorhinus sumatrensis. Sixteen years on it is timely to evaluate whether his warnings were heeded. We review the current conservation status of D. sumatrensis throughout its range and the latest threats and challenges complicating efforts to conserve this species. Recent data from governments, NGOs and researchers indicate that the global population could be as low as 216, a decline from c. 320 estimated in 1995. Based on lessons learnt and expert opinions we call on decision makers to focus on two core strategies for conservation of D. sumatrensis: (1) the translocation of wild individuals from existing small, isolated or threatened forest patches into semi-in situ captive breeding programmes, and (2) a concomitant enhancement of protection and monitoring capacities in priority areas that have established these breeding facilities or have recorded relatively high population estimates and track encounter rates. At least USD 1.2 million is required to implement these strategies annually in four priority areas: Bukit Barisan Selatan and Way Kambas National Parks on Sumatra, and Danum Valley Conservation Area and Tabin Wildlife Reserve on Sabah. Given that conservation funds are rarely secure and D. sumatrensis is still in decline we call on potential donors to help secure and augment existing capacities of organizations in these four priority areas before committing resources to elucidate the status of the species in other areas such as Gunung Leuser and Taman Negara National Parks.

Background and aims – Located in the transition zone of Guineo-Congolian and Zambezian phytochoria, the Angolan provinces of Uíge and Cuanza Norte are of particular interest for floristic studies and high biodiversity is expected. Nevertheless, explorations of the vegetation are relatively rare. Our study aims to supplement a recent checklist of vascular plants of Angola. Methods – Data were collected during 17 field trips between 2013 and 2018, during which herbarium specimens were prepared for later identification of plant species. The results were compared with the current checklist as well as with other floristic works, herbarium collections and online databases relevant for the region.Key results – We document 20 new records of indigenous vascular plant species for the flora of Angola (19 species and one subspecies), including four new generic records. Furthermore, nine alien species are added to the checklist of the flora of Angola.Conclusion – Our results confirm that the flora of northern Angola is composed by elements of various adjacent areas. However, not all species present are known yet. Further botanical investigation is needed to complete our floristic knowledge of the region.

Based on the results of field research, inventory of CWU herbarium collections and study of scientific sources it was carried out the sozological assessment of rare plant species as a part of the higher aquatic flora of the Kharkiv region according to generally accepted criteria of rarity. It has been found that four species (Salvinia natans (L.) All., Trapa natans L., Utricularia intermedia Hayne, U. minor L.) are listed in the Red Book of Ukraine, the first two of which are in the Annex I of Bern Convention. The European Red List of Vascular Plants includes three species (Potamogeton acutifolius Link, P. rutilus Wolfg., Trapa natans), which have the conservation status “Near Threatened”. 27 plant species are in the Red List of Aquatic Macrophytes of Ukraine and 22 species are included in the Regional Red List of the Kharkiv region. It has been revealed that populations of six rare species (Batrachium aquatile (L.) Dumort., Potamogeton obtusifolius Mert. et Koch, P. rutilus Wolfg., Scirpus triqueter L., Vallisneria spiralis L., Wolffia arrhiza (L.) Horkel ex Wimmer) are on the border of the range. By the uniqueness for the region, one species (Salvinia natans) is considered as rare for Europe, 26 species are rare at the state level and 10 species are rare at the regional level. For 22 species there are known from one to five locations in the region. By the size of the habitat area, the most of cenopopulations of species occupy small areas (for 27 species it is less than 5 hectares). At present the location of 6 species has not been confirmed (Ceratophyllum tanaiticum Sapjeg., Potamogeton gramineus L., P. obtusifolius Mert.et W.D.J.Koch, P. praelongus Wulfen, P. sarmaticus Mäemets, Trapa natans). It has been established that populations of only 8 species are represented quite fully at the natural reserve areas of the region. On the basis of autphytosozological analysis we propose to include 22 species of vascular plants in the Regional Red List of the Kharkiv region and to exclude from it two species: Utricularia intermedia, which is in the Red Book of Ukraine and has the conservation status at the state level, and Vallisneria spiralis L., which is considered as adventive species.
