Overview

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

Syzygium koumacense faces severe threats from mining activities and urban development in its restricted range around Koumac, New Caledonia. The species' extremely limited distribution makes it highly vulnerable to habitat destruction, with nickel mining operations posing the most immediate risk to remaining populations. Invasive plant species further degrade the quality of its native forest habitat.
