Cyanea aculeatiflora

Unknown

Overview

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

Cyanea aculeatiflora faces severe pressure from invasive plant species that outcompete native vegetation and alter forest understory conditions essential for its survival. Feral ungulates, particularly pigs and goats, damage the forest floor through rooting and trampling, destroying seedlings and disrupting the delicate soil conditions required for regeneration. Habitat degradation from human development and agricultural expansion has fragmented the remaining populations across Hawaii's montane forests.

Threat summary

Habitat

This endemic Hawaiian bellflower inhabits wet and mesic montane forests at elevations between 600-1,200 meters on the islands of Maui and Molokai. It grows in the understory of native ohia and koa forests, requiring the humid, shaded conditions and rich volcanic soils characteristic of Hawaii's native forest ecosystems.
