The Red List of Ecosystems is a global standard for assessing the conservation status of ecosystems. The RLE consists of 8 categories indicating higher-to-lower threat status. Assessments are made according to a formal, transparent protocol, based on five criteria. Assessments can be conducted at global, regional, or national level. The RLE Database hosts published ecosystem assessments, their location and the threats facing them.
