Achatinella vulpina

Unknown

Overview

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

Achatinella vulpina faces severe population decline primarily due to habitat destruction from urban development and invasive plant species that alter native forest composition. Introduced predators, particularly the rosy wolf snail (Euglandina rosea), have devastated populations by directly preying on these endemic Hawaiian tree snails. Climate change compounds these pressures by altering moisture regimes essential for their survival in montane forests.

Threat summary

Habitat

This species inhabits native montane forests on the Hawaiian island of Oahu, typically found on native trees and shrubs in areas with high humidity and consistent moisture. They require intact forest canopy that maintains the cool, moist microclimate essential for their survival.
