Dendrogram shows the decision-making process by which a species’s status is categorised, and also shows the relationship between the 10 possible options of IUCN’s Red List categories. For each category, there is a definition (next to the appropriate two-letter code) and for the three threatened categories (Critical, Endangered and Vulnerable) there are additional criteria (see table).
