CRCritically Endangered
Claoxylon ooumuense
Declining
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Claoxylon ooumuense faces severe threats from habitat destruction due to urban development and agricultural expansion on Oahu. Invasive plant species compete aggressively with this endemic Hawaiian shrub, displacing it from its native forest understory. The species' extremely limited range makes it particularly vulnerable to localized disturbances and environmental changes.
Habitat
This endemic Hawaiian shrub inhabits mesic to wet forests in the understory of native ohia and koa forests on the island of Oahu. It typically grows in shaded areas with well-drained volcanic soils at elevations between 300-800 meters.
