Guidelines for the application of IUCN Red List of Ecosystems categories and criteria

The IUCN Red List of Ecosystems is a global framework for monitoring the status of ecosystems. It is part of the growing toolbox for assessing risks to biodiversity and aims to support conservation, resource use, and management decisions by identifying ecosystems most at risk of biodiversity loss. The basis of the IUCN 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 method for assessing the risk of ecosystem collapse. These Guidelines assist correct implementation of the IUCN Red List of Ecosystems Categories and Criteria by providing information on the development of the protocol and a detailed overview of the scientific foundations supporting the categories and criteria.
