Achatinella leucorrhaphe
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Achatinella leucorrhaphe 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 rats, 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 these arboreal snails require for survival.
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 high humidity and native vegetation for feeding and shelter.
