Cyanea dunbariae

Unknown

Overview

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

Cyanea dunbariae faces severe threats from invasive plant species that outcompete this native Hawaiian lobeliad for resources and habitat space. Feral ungulates, particularly pigs and goats, destroy the understory vegetation and trample seedlings, preventing natural regeneration. The species' extremely limited population size makes it vulnerable to stochastic events and genetic bottlenecks that could drive it to extinction.

Threat summary

Habitat

Cyanea dunbariae inhabits native wet montane forests on the Hawaiian island of Molokai, typically growing in shaded understory areas with rich, well-drained volcanic soils. The species requires the specific microclimate conditions found in these high-elevation native forest ecosystems.

Frequently asked questions

Why is Cyanea dunbariae classified as Critically Endangered?
Cyanea dunbariae is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Cyanea dunbariae faces severe threats from invasive plant species that outcompete this native Hawaiian lobeliad for resources and habitat space. Feral ungulates, particularly pigs and goats, destroy the understory vegetation and trample seedlings, preventing natural regeneration. The species' extremely limited population size makes it vulnerable to stochastic events and genetic bottlenecks that could drive it to extinction.
Where does Cyanea dunbariae live?
Cyanea dunbariae occurs in United States. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Cyanea dunbariae?
The main threats to Cyanea dunbariae are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
