Overview

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

Achatinella bulimoides faces severe population decline primarily due to habitat destruction from urban development and agricultural conversion of native Hawaiian forests. Introduced predators, particularly the rosy wolf snail (Euglandina rosea) and various ant species, have devastated remaining populations through direct predation. Climate change compounds these pressures by altering the cool, moist montane conditions essential for this species' survival.

Threat summary

Habitat

This endemic Hawaiian tree snail inhabits native montane forests on Oahu, typically found on native vegetation including ohia lehua trees and understory plants in cool, moist conditions between 1,200-2,000 feet elevation. The species requires the specific microclimate conditions of intact native forest ecosystems with high humidity and stable temperatures.

Frequently asked questions

Why is Achatinella bulimoides classified as Critically Endangered?
Achatinella bulimoides 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. Achatinella bulimoides faces severe population decline primarily due to habitat destruction from urban development and agricultural conversion of native Hawaiian forests. Introduced predators, particularly the rosy wolf snail (Euglandina rosea) and various ant species, have devastated remaining populations through direct predation. Climate change compounds these pressures by altering the cool, moist montane conditions essential for this species' survival.
Where does Achatinella bulimoides live?
Achatinella bulimoides occurs in Indonesia, and 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 Achatinella bulimoides?
The main threats to Achatinella bulimoides 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.
