Red Lists are important conservation tools because they attempt to estimate the extinction risks of species. We compared the conservation status of Brazilian mammals presented in the Brazilian Red Book with those presented in the IUCN Red List, highlighting the importance of each list and why they should be used jointly. Out of 636 species, 181 were considered endemic to Brazil and 121 were considered threatened by at least one of the lists. Considering the complete database, 86 % of the species had the same status on both lists, whereas only 48 % of the threatened species had the same status. Some possible factors responsible for variations are the period in which the evaluations were carried out, the evaluation process and the fact that a species threatened nationally may not be threatened globally. We recommend that communication should be improved, that lists should be kept updated, and that both the type of information and the data itself to be used in the assessments should be standardized.

Red Listing of Threatened species is recognized as the most objective approach for evaluating extinction risk of living organisms which can be applied at global or national scales. Invertebrates account for nearly 97% of all animals on the planet but are insufficiently represented in the IUCN Red Lists at both scales. To analyze the occurrence of species present in regional Red Lists, accounts of 48 different countries and regions all over the world were consulted and all data about myriapods (Myriapoda) ever assessed in Red Lists at any level assembled. Myriapod species assessments were found in eleven regional Red Lists; however, no overlap between the species included in the global IUCN Red List and the regional ones was established. This means that myriapod species considered threatened at regional level may not be eligible for international funding specific for protection of native threatened species (more than US$ 25 million were available in the last decade) as most financial instruments tend to support only threatened species included in the IUCN Red List. As the lack of financial resources may limit protection for species in risk of extinction, it is urgent to increase the possibilities of getting financial support for implementation of measures for their protection. A Red List of all Myriapoda species recorded in Red Lists at national or local (596) and global (210) scales totaling 806 species is presented. This list shows for the first time an overview of the current conservation status of Myriapoda species. Here, the urgent need of establishing a Myriapoda Specialist Group in the Species Survival Commission of IUCN is also stressed.

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.

One of the main task of Cibodas Botanical Garden (CBG) is to conserve the Indonesian plants species. Moreover, the preservation and enrichment of threatened plant collections based on IUCN red list categories became an important programme for plants conservation in CBG. The aims of this study are to inventory threatened plant collections and to review the status of CBG threatened plant collections. List of threatened plant collections was gathered from SINDATA, a system developed by CBG. The collection, was reviewed by inspecting current collections in CBG. Literature study was done to review the conservation status of the threatened plant collections. The conservation status was checked in IUCN red list website. The results shown that CBG had collected 86 species of threatened plants, which is 13 Critically Endangered (CR) species, 39 Endangered (EN) species, and 34 Vulnerable (VU) species. Critically endangered category consists of 13 species belong to 8 families and 10 genus. Endangered category consists of 39 species belong to 17 families and 34 genus. Vulnerable category consists of 34 species belong to 27 families and 28 genus. The largest collections of threatened species was genus Nepenthes, which is 16% (14 species) from the total threatened species in CBG. Furthermore, CBG had succeeded in collecting 40 species of Indonesian native plants in which Dipterocarpaceae species were dominate the collection with 7 species. These species are listed as critically endangered (3 species) and endangered (4 species).

In many developing countries, threatened species lists are unavailable and IUCN Red Lists are very incomplete. Because limited resources are available for conservation in developing countries, detailed field assessments and scientific study of threatened species are often not feasible. However, considerable knowledge about biodiversity exists among experts and local land users. We used questionnaires as part of field surveys to compile information about the abundance, conservation threats, distribution, and ecology of populations of four threatened and iconic target species in Fiji (Acmopyle sahniana, Dacrydium nausoriense, Podocarpus affinis [all Podocarpaceae], and Cynometra falcata [Leguminosae]). These questionnaires were completed in the field for all known populations by an assessor, compiling field observations and measurements with information from local land users and local and outside experts. For the four species in this study, the questionnaires improved estimates of population size, identified previously unknown populations, provided estimates of regeneration, and identified key conservation threats. Species of highly fragmented remnants in drier climates were less protected than those in more contiguous forests of moist climates. The methods employed provided rapid, cost-effective information that can be used to revise IUCN Red List and conservation status assessments and are applicable to other Pacific Island and developing countries.

Birds, especially raptors, play important roles in ecosystems. We examine the International Union for the Conservation of Nature’s (IUCN) Red List to determine which orders of birds have proportionally more or fewer species listed as threatened or declining compared to the Class-wide average. We further examine whether raptors are more threatened or declining than non-raptors and whether the order Accipitriformes is particularly threatened even when excluding Old World vultures – which are especially imperiled. Our results reveal heterogeneity across bird orders in proportions of threatened and declining species, with some orders having greater or lower proportions than the Class-wide proportion. We also show that the proportions of threatened species in each order are correlated with the proportion of declining species. Raptors have both greater proportions of threatened and declining species than non-raptors and Accipitriformes has greater-than-average proportions of threatened and declining species, even if Old World vultures are removed from the analysis. Our results should serve as a framework for discussion of the relative conservation status of bird orders, especially raptors, which are in need of increased conservation attention.

An assessment of the conservation status of the palm species occuring in New Caledonia is provided, based on the new IUCN Red List categories. To determine the conservation status of each species, their extent of occurrence was determined using locality data on herbarium collections. Area of occupancy, number of adults, regeneration, and threats were evaluated on 62 localities throughout the Territory, including all types of palm habitats and all localities of species occurring at less than five sites. Among the 37 palm species known in New Caledonia, all are endemic and 13 are in a threatened category, including four critically endangered, one endangered, and eight vulnerable. Only four of the threatened species are represented in a reserve. Six species are listed as LRcd since they are adequately protected in a reserve despite an acute restriction of their range. Recommendations are given to improve the network of protected areas to include more threatened species.

A direct observation survey of birds on a 2 km transect carried out in Kampung Baung Bayam,Kelantan revealed at least 20 species of birds. Yellow-vented Bulbul (Pycnonotus goiavier), ZebraDove (Geopelia striata), Jungle Myna (Acridotheres fuscus), Common Myna (Acridotheres tristis)and White-throat Kingfisher (Halcyon smyrnensis) were commonly spotted during this study. Acheck on the conservation status in the IUCN Red List of Threatened Species indicates that there isa need to add more data on avifauna in this area for conservation planning and management.

Asteraceae is one of the most abundant families of the Brazilian flora, and it stands out on Brazilian red lists due to the large number of endangered and data-deficient species, since it is difficult to define a conservation status for the latter. A comparative analysis of red lists of the Brazilian flora focused on the Asteraceae is important, so we can assess the true degree of threat to which these plants are subjected faced with increasing environmental degradation. Our analysis compared red lists, and pointed out the most threatened species or data-deficient areas, species and genera. The study was based on the first and the current Official List of Endangered Species of the Brazilian Flora, and the Brazilian Flora Red List of Fundação Biodiversitas. Species were organized according to the endangered and data-deficient IUCN categories. Endangered species were also classified according to threat category. The highest numbers of threatened species were observed in the Cerrado, in the southeastern region, and in the state of Minas Gerais, as well as in the genera Lychnophora Mart., Vernonia Schreb., and Richterago Kuntze. The genera Aspilia Thouars, Baccharis L., Calea L., Eupatorium L., Mikania Willd., Piptocarpha R.Br., and Senecio L. have the greatest number of data-deficient species. Since the current Official List does not make clear its threat criteria, the Red List of Fundação Biodiversitas best portrays the situation of endangered Asteraceae species; thus, this analysis provides important information for projects aimed at the conservation of threatened and data-deficient species.

Abstract The giant otter Pteronura brasiliensis, categorized as Endangered on the IUCN Red List, was once widely distributed throughout South America. By the middle of the 20th century the giant otter had become locally extinct along the main rivers of the Orinoco basin. Although some populations seem to have recovered, the paucity of information available does not permit a full evaluation of the species' conservation status. The objective of this study was to estimate the abundance and density of the giant otter population along the Orinoco river in the municipality of Puerto Carreño, Vichada, Colombia, where there is important commercial and recreational fishing. Thirty-nine linear km were surveyed, repeatedly, with a total of 315 km of surveys. Population size was estimated by direct counts of individuals. All individuals detected were photographed and identified individually from their throat pelage patterns. In total, 30 otters were identified, giving a minimum density of 0.77 individuals per km, one of the highest reported for the species in Colombia. Given the high density in this well-developed area, our results highlight the importance of this population for the conservation of the species.
