Overview

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

Achatinella fulgens 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) and various rat species, have devastated remaining populations through direct predation. Climate change compounds these pressures by shifting rainfall patterns and temperature ranges that affect the delicate moisture balance required for this arboreal species' survival.

Threat summary

Habitat

This endemic Hawaiian tree snail inhabits native montane forests on Oahu, typically found on native trees and shrubs in mesic to wet forest zones at elevations between 300-800 meters. The species requires specific microhabitat conditions with consistent moisture levels and native vegetation for both shelter and food sources.

Frequently asked questions

Why is Achatinella fulgens classified as Critically Endangered?
Achatinella fulgens 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 fulgens 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) and various rat species, have devastated remaining populations through direct predation. Climate change compounds these pressures by shifting rainfall patterns and temperature ranges that affect the delicate moisture balance required for this arboreal species' survival.
Where does Achatinella fulgens live?
Achatinella fulgens 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 Achatinella fulgens?
The main threats to Achatinella fulgens 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.
