Pre-publication
Red List and Green Status assessments are usually published biannually, with new and updated assessments being associated with specific versions of the IUCN Red List. However, occasionally it is necessary to provide access to assessments that have been processed and accepted for publication in between Red List updates for use in rare and specific situations (e.g., legal cases, listings under international conventions, etc.). For these exceptional cases, accepted pre-publication assessments are made available below on a temporary basis. Users will be redirected to the published assessments once the PDF versions are available after the next update of the IUCN Red List.
