To identify major threats to groupers, the International Union for Conservation of Nature (IUCN) Red List criteria were applied to all 163 species. Red List assessments show that 20 species (12%) risk extinction if current trends continue, and an additional 22 species (13%) are considered to be Near Threatened. The Caribbean Sea, coastal Brazil and Southeast Asia contain a disproportionate number of Threatened species, while numerous poorly documented and Near Threatened species occur in. IUCN Red List Categories and Criteria. The IUCN Red List Categories and Criteria are intended to be an easily and widely understood system for classifying species at high risk of global extinction. This second edition of the IUCN Red List Categories and Criteria: Version 3.1 retains the same assessment system presented in the first edition What is the Red List of Ecosystems? The IUCN Red List of Ecosystems Categories and Criteria is a global standard for how we assess the status of ecosystems, applicable at local, national, regional and global levels. Assessments determine whether an ecosystem is not facing imminent risk of collapse, or whether it is vulnerable, endangered, or critically endangered. This will be measured by assessing losses in area, degradation or other major changes such as land conversion has been used as the standard for global Red List assessments published on the IUCN Red List of Threatened SpeciesTM. It is also used alongside the Guidelines for Application of IUCN Red List Criteria at Regional and National Levels (IUCN 2003, 2012), by many countries around the world as a standard system for national Red List assessments. Over the last decade, the IUCN Red List Categories and Criteria have been used t
Red List assessors are required to provide with each assessment, along with relevant formats and standards, with a particular focus on the distribution map. 1.1 Why spatial data are required Spatial data are some of the most highly sought-after data on the IUCN Red List as they are crucial information for conservation planning. Each assessment should provid at the IUCN Red List Criteria following which, changes were proposed affecting the criteria, the definitions of some key terms and the handling of uncertainty. Version 3.1: IUCN (2001) The IUCN Council adopted this latest version, which incorporated changes as a result of comments from the IUCN and SSC memberships and from a final meeting of the Criteria Review Working Group, in February 2000.

Gland, Switzerland: IUCN. ix + 96p. A practical guide to the application of the IUCN Red List of Ecosystems criteria IUCN Red List of Threatened Species, objective assessment system for classifying the status of plants, animals, and other organisms threatened with extinction. Unveiled in 1994, the list contains criteria and categories to classify species on the basis of their probability of extinction
Global IUCN Red List of Threatened Species™ Statistics: Based on species status assessments by 300+ experts using the IUCN Red List criteria, the SSG classified: 181 shark & ray species (17.4% of all species assessed) a taxa below the rank of variety (e.g., forma, morph, cultivar), are NOT included on the IUCN Red List, with the exception of assessments of subpopulations. Before assessments of taxa below the species level (subspecies, variety or subpopulation) can be included on the IUCN Red List, an assessment of the full species is also required
IUCN - SSC Cetacean Specialist Group / 2001 IUCN Red List Categories and Criteria (version 3.1) assessment of its risk of extinction based on its distribution and/or population status. A taxon in this category may be well studied, and its biology well known, but appropriate data on abundance and/or distribution are lacking. Data Deficient is therefore not a category of threat. Listing of. The basis of the IUCN Red List of Ecosystems are the IUCN Red List of Ecosystems Categories and Criteria, a set of eight categories and five criteria that provide a consistent method for assessing an ecosystem's risk of collapse The IUCN Red List is based upon precise criteria to evaluate the rate of extinction of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. The IUCN red list provides taxonomic data, conservation status, and distribution information on species that are facing a high risk of global extinction

Preparing IUCN Red List assessments requires comprehensive knowledge on the application of the IUCN Red List Categories and Criteria, to ensure that assessments are conducted according to scientifically underpinned and exacting standards. This process differs slightly depending on whether you are a Global Assessor assessing the global extinction risk of species for publication on the IUCN Red List, or a Regional Assessor assessing species' subglobal extinction risk for a regional or. Title: Australia: Integrating outcomes of IUCN red list of ecosystems assessments for connected coastal wetlands Author(s): Sievers, M., Pearson, R. M., Turschwell, M. P., Bishop, M. J., Bland, L., Brown, C. J., Tulloch, V. J. D., Haig, J. A., Olds, A. D., Maxwell, P. S. & Connolly, R. M However, misconceptions of the Red List assessment process, along with its technically demanding nature, can result in the misapplication of their criteria, leading to inconsistent and potentially unreliable assessments. To address this problem, we developed redlistr, an R package aiding in the production of consistent species and ecosystem Red List assessments. Redlistr's features include. How Red List Assessments Work: IUCN Criteria And Categories. Red List categories provide an approximate measure of species' extinction risk in a given region, by quantitatively evaluating some of the key symptoms of risk: (i) a trend in population size or distribution, (ii) rarity (abundance) and/or restriction (geographic range), and (iii) population size (number of reproductive individuals.
Step 2 - Preliminary assessment. In this step, the IUCN Red List Categories and Criteria are applied to the entire population occurring within the region, and all populations outside of the assessment region are ignored and the Red List criteria are applied without any modifications to thresholds, etc. Step 3 - Producing the final regional assessment . In this step, the potential rescue. The IUCN Red List is set upon precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. The aim is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to try to reduce species extinction. Major species assessors include. Red List Guidelines 5 Subpopulations: If a subpopulation assessed under the criteria is not isolated (i.e., if it may be exchanging individuals with other subpopulations), its assessments must follow the regional guidelines (IUCN 2003, 2012a)

The IUCN Red List, the world's most widely-used database of endangered species, ignores hundreds of birds that face immediate risk of extinction. This is because the IUCN's current criteria for classifying species as threatened has not been updated in 25 years. Their dated system doesn't use new geospatial mapping technologies, and therefore. Consequently, the assessment not only presented the threatened status of Hebei flora but also indicated the relatively fragile health status of the environment of Beijing and Tianjin. Thus, it is suggested that the application of the IUCN Red List Criteria at the regional level, as an index, could reflect the health status of the local ecosystem. In addition, more concrete measures are needed. Assessment Information Red List Category & Criteria: Near Threatened ver 3.1 Year Published: 2008 Date Assessed: June 30, 2008 Justification: There is little direct information on the status of this species. However, it is probably declining due to over-hunting, like Capricornis milneedwardsi, and so it is listed as Near Threatened because this species is believed to be in significant decline. In this contribution, the conservation status assessment of three vascular plants according to IUCN categories and criteria are presented.
