This study evaluates the conservation status of14 Rungia Nees species occurring in Thailand. All species were assessed and assigned to an extinction risk category following the IUCN Red List Categories and Criteria. Justifications for the assessments, together with distribution maps for each species, are provided. The results show that more than half of the species are threatened, including five Critically Endangered (CR), five Endangered (EN) and two Vulnerable (VU). The remaining two species are not currently at risk of extinction, comprising one Near Threatened (NT) and one Least Concern species (LC). These conservation assessments offer a critical foundation for guiding and prioritising future in situ and ex situ conservation efforts.
