Achatinella sowerbyana
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Achatinella sowerbyana faces severe population decline primarily due to predation by introduced species, particularly the rosy wolfsnail (Euglandina rosea) and various rat species that consume both adults and eggs. 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 and temperature conditions required for these arboreal snails in Hawaii's montane forests.
Habitat
This endemic Hawaiian tree snail inhabits native montane forests on Oahu, typically found on native trees and shrubs in areas with high humidity and consistent moisture. The species requires intact forest canopy and native vegetation communities that provide both food sources and the specific microclimate conditions necessary for reproduction and survival.
