Achatinella viridans
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Achatinella viridans faces severe population decline primarily due to predation by introduced species, particularly the rosy wolfsnail (Euglandina rosea) and rats, which consume both adults and juveniles. Habitat degradation from invasive plant species and human development has fragmented the remaining native forest areas essential for this species' survival. Climate change poses an additional threat by altering the moisture regimes and temperature conditions required for this moisture-dependent snail.
Habitat
Achatinella viridans inhabits native Hawaiian montane forests, particularly areas with high humidity and dense canopy cover that provide the moist microclimate essential for survival. The species is typically found on native trees and shrubs in elevations ranging from 300 to 800 meters in the Waianae Mountains of Oahu.
