The Status

The great raft spider, Dolomedes plantarius, is a semi-aquatic spider species with an Eurosiberian distribution. As a result of habitat loss and degradation, in 1996 the species was classified as Vulnerable in the IUCN Red List of Threatened Species, but since then the status has never been updated. We present the frame of the existing knowledge on the distribution of this rare spider species in Italy, based on literature data and on original records gathered in recent years. Finally, we discuss the conservation value of the Italian populations, in light of their peripheral position within the species range and in light of the future reduction of the bioclimatic range of the species due to climate and land cover changes associated with anthropic disturbance

The Impact

<p>Ikan banggai cardinal atau disingkat BCF adalah jenis ikan hias tropis endemik yang hanya hidup secara alami di perairan sekitar Kepulauan Banggai. Dampak tekanan penangkapan terhadap populasi BCF dewasa ini cukup signifikan, yaitu terjadinya gejala overfishing telah nampak pada hampir semua lokasi penangkapan. Status BCF pada saat ini dalam Red List IUCN tergolong Threatened Species. Tulisan ini menyajikan pengelolaan sumber daya BCF dengan mengkaji status pemanfaatan, dinamika populasi, biologi dan habitatnya. Data yang digunakan adalah hasil penelitian pada tahun 2011, melalui validasi data di lapangan dan telaah dari hasil-hasil penelitian sebelumnya. Hasil tangkapan BCF relatif tinggi pada kisaran tahun 1999 – 2007, mencapai 1,4 juta ekor pada tahun 2000, kemudian menurun drastis pada tahun 2008 – 2010, hanya berkisar 250.000 – 350.000 ekor/tahun. Upaya pengelolaan BCF telah dilakukan sejak tahun 2005, baik oleh pemerintah pusat, pemerintah daerah, maupun melalui kearifan lokal yang ada. Implementasi kebijakan pengelolaan BCF di perairan Kepulauan Banggai berdasarkan kajian hasil penelitian adalah jumlah kuota BCF yang boleh ditangkap sebanyak 220.615 ekor/tahun dengan ukuran minimal 4,8 cm (FL) dan tidak dalam kondisi mengerami telurnya. Mengingat umur dari BCF berkisar antara 2-4 tahun, maka kuota dapat diberlakukan selama jangka waktu 3 tahun. Monitoring data hasil tangkapan BCF melalui kegiatan enumerasi harus tetap dilanjutkan sebagai bahan evalusi status stok sumberdaya tersebut.</p><p>Banggai cardinal fish (BCF) is an endemic tropical ornamental fish that only inhabits naturally in the Banggai Islands. The impact of fishing pressure on the BCF population is quite significant, i.e. overfishing is occurring in almost all fishing areas. BCF is listed in the IUCN Red List as Threatened Species group. This paper presents the fisheries management for BCF by assessing the status of its utilization, population dynamic, biology and habitat. The data analyzed in this paper were conducted in 2011, through data validation in the field and review on some previous studies. The catch production of BCF was relatively high between 1999 and 2007, reached 1.4 million fish in 2000, followed by a significant decrease from 250.000 in 2008 to 350.000 in 2010. Fisheries management measures for BCF have been initiated since 2005, either by central or local governments, or the available local wisdom. The results of study recommend catch quota for BCF, that maintain the sustainability of the fish stock, is 220.615 fish/year, with the minimum size is 4.8 cm FL and not in the condition of incubating eggs. Since the age of BCF is between 2-4 years old, the recommendation could be implemented for 3 years, and data monitoring through enumeration could be continued for evaluation of its stock status.</p>

Dynamics Of Population

It is important to understand the dynamics of population size to accurately assess threats and implement conservation activities when required. However, inaccurate estimates are harming both the threat estimation process, and the resulting conservation actions. Here, we address the extinction threats to Scincella huanrenensis, a species described in the People’s Republic of China, but also occurring on the Korean peninsula. Estimating the threats to the species is not an easy task due to its unknown population status in the Democratic People’s Republic of Korea. Here we analysed the literature to acquire the known presence point for the species, along with datapoints originating from opportunistic field surveys, and employed habitat suitability models to estimate the range of the species. We then followed the categories and criteria of the IUCN Red List of Threatened Species to assess the extinction risk of the species. We found the species not to be fitting the threatened category at the global scale based on the range size, the only category for which enough data was available. We recommend the status of the species on the IUCN Red List of Threatened Species to be updated as it is now listed as critically endangered (CR), a listing fitting a national assessment for the People’s Republic (PR) of China. While this species is possibly less threatened than currently listed, this is not a genuine improvement, and specific conservation aspects should not be neglected due to its specialisation to medium to high elevation habitat.

Technical Capacity

We argue that botanic gardens, as plant conservation focused institutions, have been tested in temperate regions that possess a relatively robust conservation infrastructure and a relatively low number of threatened species. The ability of the Brazilian botanic gardens to support plant conservation is especially challenging, given their small number relative to Brazil’s plant diversity and the increasing rate of habitat loss and plant endangerment. This study, the first for Brazil, assesses the conservation capacity of Brazilian botanic gardens. An assessment is made of the status of conservation facilities in Brazilian botanic gardens and the conservation status of their plant collections.This was based on a survey sent to thirty-six Brazilian botanic gardens in 2011– 2013 using information from the 2008 Brazilian Red List, and seven state conservation lists. The results identified a small percentage of threatened species (n =102/21 per cent) in ex situ collections of 22 botanic gardens and less than 10 per cent representation for each state red list. An assessment based on the updated Brazilian Red List (2014) showed that 425 threatened species were maintained in living collections of 18 botanic gardens. Despite the extensive size of some collections, the proportion of threatened species in the collections was found to be very low. Improvement in infrastructure, technical capacity, including horticultural skills, and development of policies and protocols will benecessary to increase the effectiveness of the collections for conservation aims.

Sawfishes (Pristidae) are large shark-like batoids with a distinctive flattened, greatly elongated rostrum armed on each side with a row of large transverse teeth. Two genera and at least four species occur in the Indo-West Pacific, of which Anoxypristis cuspidata (Latham, 1794), Pristis microdon Latham, 1794 and P. zijsron Bleeker, 1851 have widespread distributions and P. clavata Garman, 1906 appears to be restricted to northern Australia (Compagno & Last, 1999; Last & Stevens, 2009; Phillips et al., 2011). All sawfishes are threatened by over fishing and habitat loss, with range reductions and local extinctions reported for several species (Simpfendorfer, 2000; Monte-Luna et al., 2007; Last & Stevens, 2009; Wueringer, et al. 2009; Phillips et al., 2011). All Indo-Pacific sawfishes are assessed by the IUCN as Critically Endangered with decreasing population trends (IUCN Red List of Threatened Species, http://www.iucnredlist.org/, 10 Sep. 2011).

Indonesia is home to five species of porcupines, three of which are island endemics. While all five species are currently assessed as Least Concern by the IUCN Red List of Threatened Species, impacts of harvest and trade have not been factored in. To gain a fuller understanding of the porcupine trade in Indonesia, this study examines seizure data of porcupines, their parts and derivatives from January 2013 to June 2020. A total of 39 incidents were obtained amounting to an estimated 452 porcupines. Various confiscated commodities revealed porcupines are traded for consumption, traditional medicine, trophies/charms as well as for privately run wildlife/recreational parks. Targeted hunting of porcupines for commercial international trade was also evident. Porcupines are also persecuted as agricultural pests and wildlife traffickers take advantage of such situations to procure animals for trade. What clearly emerges from this study is that porcupines are being illegally hunted and exploited throughout their range in Indonesia facilitated by poor enforcement and legislative weakness. Porcupines are in decline due to habitat loss, retaliatory killings and uncontrolled poaching. It is therefore crucial that effective conservation measures are taken sooner rather than later to prevent further depletion of these species. Including all porcupines as protected species under Indonesian wildlife laws and listing them in Appendix II of CITES to improve regulation, enforcement and monitoring of domestic and international trade trends involving porcupines in Indonesia would contribute significantly towards this end.

Given the economic and cultural dependence on the marine environment in Oceania and a rapidly expanding human population, many marine species populations are in decline and may be vulnerable to extinction from a number of local and regional threats. IUCN Red List assessments, a widely used system for quantifying threats to species and assessing species extinction risk, have been completed for 1190 marine species in Oceania to date, including all known species of corals, mangroves, seagrasses, sea snakes, marine mammals, sea birds, sea turtles, sharks, and rays present in Oceania, plus all species in five important perciform fish groups. Many of the species in these groups are threatened by the modification or destruction of coastal habitats, overfishing from direct or indirect exploitation, pollution, and other ecological or environmental changes associated with climate change. Spatial analyses of threatened species highlight priority areas for both site- and species-specific conservation action. Although increased knowledge and use of newly available IUCN Red List assessments for marine species can greatly improve conservation priorities for marine species in Oceania, many important fish groups are still in urgent need of assessment.

Abstract Cactaceae is one of the most threatened plant families, in part as a result of the illegal extraction of plants for ornamental use. However, reports of the seizure and reintroduction of cacti are scarce and do not include species of Melocactus, the genus of Cactaceae in Brazil that has the highest number of threatened species. The coroa-de-frade Melocactus violaceus is endemic to Brazil and categorized as Vulnerable on the IUCN Red List. We report the seizure of 37 individuals of coroa-de-frade extracted illegally from their natural habitat, the results of their reintroduction to Paulo César Vinha State Park, in Espírito Santo state, Brazil, and provide information for environmental monitoring agencies regarding how to proceed in seizure cases, with the goal of minimizing the impacts of this illegal practice on the species. After seizure, 25 individuals were cultivated in a greenhouse and 12 were reintroduced in restinga, the natural area of occurrence of the species. After 6 months, survival was 76% for those individuals cultivated in the greenhouse and 84% for those planted in restinga, showing that rapid reintroduction of species with ornamental appeal, preferentially in their natural habitat, can reduce the impacts of illegal extraction. This reintroduction protocol can be used by managers of conservation units, contributing to the maintenance of threatened cactus species in their natural habitat.

The Action Plan for Australian Birds 2010 is the third in a series of action plans that have been produced at the start of each decade. The book analyses the International Union for Conservation of Nature (IUCN) status of all the species and subspecies of Australia's birds, including those of the offshore territories. For each bird the size and trend in their population and distribution has been analysed using the latest iteration of IUCN Red List Criteria to determine their risk of extinction. The book also provides an account of all those species and subspecies that are or are likely to be extinct. The result is the most authoritative account yet of the status of Australia's birds. In this completely revised edition each account covers not only the 2010 status but provides a retrospective assessment of the status in 1990 and 2000 based on current knowledge, taxonomic revisions and changes to the IUCN criteria, and then reasons why the status of some taxa has changed over the last two decades. Maps have been created specifically for the Action Plan based on vetted data drawn from the records of Birds Australia, its members and its partners in many government departments. This is not a book of lost causes. It is a call for action to keep the extraordinary biodiversity we have inherited and pass the legacy to our children. 2012 Whitley Award Commendation for Zoological Resource.
