A new version of one of the key documents for Red List of Ecosystems assessment is now available. These Guidelines aim to support assessors by providing detailed information and examples of how to apply the IUCN Red List of Ecosystems Categories and Criteria.
The IUCN Red List of Ecosystems is a global framework for monitoring the status of ecosystems. The basis of the Red List of Ecosystems is the IUCN Red List of Ecosystems Categories and Criteria, a set of eight categories and five criteria that provide a consistent, objective method for assessing the risk of ecosystem collapse.
The Guidelines for the application of IUCN Red List of Ecosystems Categories and Criteria assist ecosystem assessors by providing a detailed overview of the scientific foundations supporting the categories and criteria, including descriptions of ecosystem types, ecosystem collapse, and the risk assessment protocol, as well as a thorough explanation of the assessment process.
These Guidelines describe in detail how to define the assessment area, define the ecosystem type, apply each of the criteria (A-E), and prepare the assessment documentation for peer review and publication. All steps are illustrated with examples spanning a wide range of ecosystem types, geographical locations and levels of data availability.
Version 1.1 of the Guidelines is available in English, and will very soon be released in French and Spanish. With respect to version 1.0, published in 2016, this new version includes some changes, new sections and figures, small changes in definitions of terms, and the most relevant, the incorporation of recent research on performance of rage size measures.
