Illegal hunting and trading of the Chinese Pangolin Manis pentadactyla has pushed this Critically Endangered species close to extinction.  While local reports have suggested its continued presence in mainland China, this has not been confirmed by a research group except for a survey of presumed pangolin burrows in 2004.  We conducted a six-month field study using infrared camera surveillance and community questionnaire survey in Zhejiang Wuyanling National Nature Reserve in China, to determine the status of Chinese Pangolins and understand local attitudes towards the conservation of this species.  Our study details the first verifiable documentation of two visual records of a Chinese Pangolin in the wild, demonstrating the suitability of pangolin habitat in Wuyanling region, and suggests an increasing awareness and strong willingness in local communities to conserve the Chinese Pangolin.

ABSTRACTIndonesia has a high diversity of fish species. Some fish species are critical and endangered. Information on Indonesian native and endemic fish species needs to be disseminated to the public. Such information is available in various sources and is generally in a foreign language. Therefore, the purpose of this research is to inventory and distribute information about several species of fish native to Indonesian public waters that need special attention because they are endangered and critically endangered. Species of fish, especially species that have been critically endangered, do not rule out turning into extinct in the wild (extinct in the wild). The decline in the status of the above from vulnerable (vulnerable) to endangered (endangered) and critical (critically endangered) or even become extinct in the wild (extinct in the wild) caused by various factors, including the existence of fisheries activities that tend to exploit natural resources without offset by conservation activities and increasing pollution of water conditions. With this information, it is expected to anticipate the extinction of these species. The study was conducted using the literature study method. Based on the search results, there were 22 endangered fish species and 15 critically endangered fish species. The Indonesian government has designated 20 protected fish species. Domestication of endangered and critical species is urgent to do, to prevent the extinction of these species. ABSTRAKIndonesia memiliki keanekaragaman spesies ikan yang tinggi. Beberapa spesies ikan sudah kritis dan terancam punah. Informasi jenis-jenis ikan asli dan endemik Indonesia perlu diserbarluaskan ke masyarakat. Informasi tersebut terdapat diberbagai sumber dan umumnya berbahasa asing. Oleh karena itu, tujuan penelitian ini adalah untuk menginventarisasi dan mendistribusikan informasi tentang beberapa spesies ikan asli penghuni perairan umum Indonesia yang perlu mendapat perhatian khusus karena berstatus terancam punah (endangered) dan kritis (critically endangered). Spesies-spesies ikan tersebut terutama spesies yang sudah berstatus kritis terancam punah, tidak menutup kemungkinan berubah menjadi punah di alam liar (extinct in the wild). Terjadinya penurunan status diatas dari rentan (vulnerable) ke terancam punah (endangered) dan kritis (critically endangered) atau bahkan menjadi punah di alam liar (extinctin the wild) disebabkan oleh berbagai macam faktor, diantaranya adanya kegiatan perikanan yang cenderung mengeksploitasi sumber daya alam tanpa diimbangi dengan kegiatan konservasi serta meningkatnya pencemaran terhadap kondisi perairan. Dengan adanya informasi ini diharapkan dapat melakukan antisipasi pencegahan kepunahan spesies tersebut. Penelitian dilakukan dengan metode studi literatur. Berdasarkan hasil penelusuran, diperoleh 22 spesies ikan yang terancam punah (endangered) dan 15 spesies ikan yang sudah kritis (critically endangered). Pemerintah Indonesia telah menetapkan 20 spesies ikan yang dilindungi. Domestikasi spesies-spesies yang terancam punah dan kritis sudah mendesak untuk dilakukan, untuk mencegah kepunahan spesies tersebut.

AbstractThe Myanmar snub-nosed monkey Rhinopithecus strykeri was discovered in 2010 on the western slopes of the Gaoligong Mountains in the Irrawaddy River basin in Myanmar and subsequently in the same river basin in China, in 2011. Based on 2 years of surveying the remote and little disturbed forest of the Gaoligong Mountains National Nature Reserve in China, with outline transect sampling and infrared camera monitoring, a breeding group comprising > 70 individuals was found on the eastern slopes of the Gaoligong Mountains in the Salween River Basin. Given the Critically Endangered status of this primate (a total of < 950 individuals are estimated to remain in the wild), efforts to protect the relatively undisturbed habitat of this newly discovered population and to prevent hunting are essential for the long-term survival of this species.

Abstract One of the three Critically Endangered and endemic primate species in Viet Nam, Delacour's langur Trachypithecus delacouri, is restricted to the north of the country. The largest remaining population is in Van Long Nature Reserve, Ninh Binh Province, and the second largest is in nearby Kim Bang Protection Forest, Ha Nam Province, with other populations believed to be too small for recovery. The population in Van Long has been well studied but the status of that of Kim Bang has not previously been adequately evaluated. To address this, a survey was conducted during 10 August–7 October 2018. In total, we recorded 13 groups comprising a total of at least 73 individuals, almost doubling the highest number reported in previous studies. We documented six new groups in Lien Son and Ba Sao communes in Kim Bang. Our findings indicate there is a high likelihood that Delacour's langur population in Kim Bang will recover and could be important for the long-term conservation of this Critically Endangered species. However, immediate and appropriate conservation measures need to be implemented to protect the population from major anthropogenic threats, namely poaching and habitat destruction, detected during our survey.

Bird species extinctions in the Atlantic Forest of Brazil have been predicted since the early 1990s, but it has become accepted wisdom that none have yet been documented. We revisit this question in light of updates to the global Red List, and conclude that between five and seven bird species have likely been driven to extinction in the wild in this biome in recent decades, plus a further two species that occurred elsewhere in Brazil. These extinctions were the result of habitat loss in combination with other threats. A further nine Atlantic Forest bird species are Critically Endangered, plus six from elsewhere in Brazil. We review growing efforts to help these species avoid extinction using a range of tools including multi-stakeholder planning, advocacy, habitat protection and restoration on public and private land, focussed research, and intensive population management, drawing on examples from the most threatened Atlantic Forest endemics. Conservation organisations, local communities, government agencies, zoos, international funders, universities and others are working together to prevent these species from disappearing. While the political environment in Brazil has rarely been more hostile to conservation, there are also some positive trends. Rates of deforestation in the Atlantic Forest have fallen, forest restoration and recovery is increasing, and an unprecedented number of ordinary people are taking an interest in birds and participating in citizen science. With dedication, collaboration, sufficient resources, and a focus on evidence-informed solutions, we are hopeful that many of the Critically Endangered species can be pulled back from the brink of extinction.

Eighty-two species or other forms of rare mammals were kept in 19 zoological gardens of the Czech Republic and Slovakia as of 1 January 2016. Two mammal species extinct in the wild (EW category of the IUCN) were bred in the zoos in 2015. Of the kept 29 critically endangered species (CR), 17 bred successfully in 2015, while of the kept 51 endangered species (EN), 25 did. Nine zoos bred more than one third of their kept species belonging to the three categories. The breeding of rare species of perissodactyls and artiodactyls was the most successful in the respective zoos.

Understanding the causes of rarity and ways of managing populations of rare species is essential for their successful conservation. The present study applies the conceptual model of a hierarchy of causes to Lasiopetalum pterocarpum E.M.Benn. & K.Shep. (a critically endangered species) to understand better its reproductive and ecological attributes, possible reasons for its rarity and to determine whether this model assists in developing management strategies. L. pterocarpum subpopulations from Serpentine National Park were censused to record abundance, plant health, phenology, flower and fruit production and the presence of any seed bank. These characteristics were matched to criteria in the hierarchies of cause model. There was no evidence of recent seedling recruitment at any subpopulation. Hand-pollination produced a flower-to-fruit conversion proportion similar to that found in the field and self- and cross-pollinations produced virtually the same fruit set. Seed store in soil from beneath the native subpopulations and at a translocation site showed seed was patchily distributed and infrequent. L. pterocarpum is an obligate seeder, killed by fire and dependent on disturbance to break seed dormancy. However, smoke has no effect on germination. Seed production does not constrain population growth, because seedling regeneration after fire in 1999 was prolific at sites where plants had been growing. In the hierarchies of cause framework, the main causes of rarity for this species are taxon ecology, life-history strategy and stochasticity. Thus, concentrating active management on factors related to life history such as mosaic patch burning, fencing after fire to exclude vertebrate grazers, weed control and establishment of translocated populations will aid the preservation of this species in the wild.

The second regional list of threatened lichens and allied fungi is presented. The list is a result of investigation studies in North-Eastern Poland. In physicogeographic regionalization this area comprises 4 macroregions: Staropruska Lowland, Litewskie (Lithuanian) Lakeland, Mazurian Lakeland and South Podlasie Lowland. It is characterized by the presence of large forest complexes, including the Białowieża Old-growth Forest, the Knyszyńska Old-growth Forest, the Augustowska Old-growth Forest, the Romincka Old-growth Forest, the Borecka Old-growth Forest and the Piska Old-growth Forest. The status of threat to the lichen and allied fungi species listed has been determined according to the IUCN Red List Categories in version 3.1 (2001). The data obtained were compared with historical ones. Changes of the species main frequency were used as an additional indicator of their threat status. The Red List includes 310 taxa of lichens, lichenicolous and saprobic fungi, which constitute 52% of the NE Poland total lichen biota and 19.4% of Polish biota. The status of threatened biota has the following categories: Regionally Extinct (RE) -49 taxa, Critically Endangered (CR) - 58, Endangered (EN) - 41, Vulnerable (VU) - 39, Near Threatened (NT) - 24, Least Concern (LC) - 19 and Data Deficient (DD) - 80. Epiphytes constitute 84% of extinct and critically endangered species.

AbstractPink-headed Duck Rhodonessa caryophyllacea is a Critically Endangered species that has not been confirmed in the wild since 1948–1949. Historical records of the species are concentrated in India, although there are also a few from Myanmar. Between 2003 and 2005, BirdLife International and the Biodiversity and Nature Conservation Association (BANCA) conducted a series of field surveys of wetland habitats in the lowlands of Kachin state, an area with a cluster of historical records of the species. These were the first targeted efforts to assess the status of the species in Myanmar. These surveys were complemented by reviews of museum specimens and literature relating to the species in Myanmar. Two specimen records represent very strong evidence that the species occurred in Myanmar historically, although they shed little light on its seasonal status in the country. The surveys conducted by BirdLife International and BANCA were unable to confirm the continued occurrence of Pink-headed Duck in Myanmar. However, they did generate a limited amount of equivocal direct evidence, most notably two possible but unconfirmed sightings. There are several reasons for believing that the species may still persist in the lowlands of Kachin state and, perhaps, elsewhere in Myanmar. Shyness, combined with rarity, possible nocturnal habits and the impenetrability of its habitats, means that the species tended to be under-recorded historically, and may continue to be so currently. Further surveys are required to confirm this.

The Status

Long-standing concerns about the status of the world's endangered primates have stimulated significant international efforts, such as the primate action plans published by the Primate Specialist Group of the International Union for Conservation of Nature's Species Survival Commission. However, national-level action plans that bring together diverse scientific experts, non-governmental organizations, and governmental agencies to focus on improving the status of endangered species are generally rare. Here, we highlight one such plan published a decade ago, the Brazilian National Action Plan for the Conservation of Muriquis, which promoted the integration of scientific findings about the behavioral ecology, demography, and genetics of northern muriquis with conservation measures supported by the Brazilian government. This plan provided a holistic framework for the development of an effective national strategy that has contributed to significant advances in research and management applied to the conservation of this Critically Endangered species. We hope that this model for muriquis will stimulate conservationists around the world to pursue integrative national-level sponsorship of action plans on behalf of other endangered species.

The main objectives of the Nepal National Mammal Red Data Book (RDB) were to provide comprehensive and up-to-date accounts of 212 mammal species recorded in Nepal, assess their status applying the IUCN Guidelines at Regional Levels, identify threats and recommend the most practical measures for their conservation.  It is hoped that the Mammal RDB will help Nepal achieve the Convention on Biological Diversity target of preventing the extinction of known threatened species and improving their conservation status.  Of the 212 mammal species assessed, 49 species (23%) were listed as nationally threatened.  These comprise nine (18%) Critically Endangered species, 26 (53%) Endangered species and 14 (29%) Vulnerable species.  One species was considered regionally Extinct.  A total of seven species (3%) were considered Near Threatened and 83 species (39%) were Data Deficient.  Over sixty percent of Nepal’s ungulates are threatened and almost half of Nepal’s carnivores face extinction (45% threatened).  Bats and small mammals are the least known groups with 60 species being Data Deficient.  Habitat loss, degradation and fragmentation are the most significant threats.  Other significant threats include illegal hunting, small and fragmented populations, reduction of prey base, human wildlife conflict and persecution, climate change, invasive species, disease and inadequate knowledge and research.  Adequate measures to address these threats are described.  It was also concluded that re-assessments of the status of certain mammal groups be carried out every five years and the setting up of a national online species database and mapping system would also greatly help in land-use planning and policies.
