Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

The Three Kings Rangiora faces severe threats from invasive plant species, particularly pigs and goats that damage its forest habitat through browsing and trampling. The species' extremely restricted range on the Three Kings Islands makes it highly vulnerable to habitat degradation and potential extinction from single catastrophic events. Introduced weeds compete directly with native vegetation, while the small population size increases risks from genetic bottlenecks and demographic fluctuations.
