Achatinella lorata

Unknown

Overview

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

Achatinella lorata 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 optimal habitat zones upslope, while the species' extremely limited dispersal ability prevents natural recolonization of suitable areas.

Threat summary

Habitat

This endemic Hawaiian tree snail inhabits native mesic and wet forests on Oahu, typically found on native trees and shrubs in areas with high humidity and moderate temperatures. The species requires intact native forest canopy and is particularly associated with ohia lehua and koa trees in elevations between 300-800 meters.

Frequently asked questions

Why is Achatinella lorata classified as Critically Endangered?
Achatinella lorata 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 lorata 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 optimal habitat zones upslope, while the species' extremely limited dispersal ability prevents natural recolonization of suitable areas.
Where does Achatinella lorata live?
Achatinella lorata occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Achatinella lorata?
The main threats to Achatinella lorata 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.
