Status assessments presented in The IUCN Red List of Threatened Species™ are open to challenge. Petitions may be made against current listings of species, subspecies or geographic subpopulations. Petitions against historical listings (i.e., those that have since been updated with a new listing for the taxon in question) are not considered.
Petitions may only be made on the basis of the IUCN Red List Categories and Criteria (version 3.1) and in reference to any supporting documentation accompanying the listing. It is not possible to change listings for political, emotional, economic, or other reasons not based on the Categories and Criteria.
For full details on the petitions process please view The Procedure for Handling of Petitions against Current Listings on the IUCN Red List of Threatened Species.
