Table 7. Guidelines on two non-consecutive plausible threat categories (based on IUCN 2019)
In some rare cases, uncertainties may result in two non-consecutive plausible status categories. This may happen, for example, when extent of occurrence (EOO) or area of occupancy (AOO) is smaller than the Endangered threshold and one subcriterion is definitively met, but it is uncertain whether a second subcriterion is also met. Depending on this, the category can be either Endangered or Special Concern. In such cases, the category could be specified as the range Endangered–Special Concern in the documentation (giving the reasons why), and the assessors must choose the most plausible of the categories, of which Threatened could be one. This choice depends on the level of precaution and should be justified.
