Achatinella swiftii
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Achatinella swiftii 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 of this endemic Hawaiian tree snail. Climate change compounds these pressures by altering moisture regimes essential for this species' survival in montane forests.
Habitat
This species inhabits native montane forests on the Hawaiian island of Oahu, typically found on native trees and shrubs in mesic to wet forest zones. It requires specific moisture conditions and native vegetation structure that provide appropriate microhabitats for feeding and reproduction.
