Achatinella pulcherrima
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Achatinella pulcherrima faces severe population decline primarily due to predation by introduced species, particularly the rosy wolfsnail (Euglandina rosea) and rats, which consume both adults and eggs. Habitat degradation from invasive plant species and urban development has fragmented the remaining native forest areas essential for survival. The species' extremely limited range on Oahu makes it particularly vulnerable to localized threats, with some populations reduced to critically low numbers in recent decades.
Habitat
This endemic Hawaiian tree snail inhabits native mesic and wet forests on the island of Oahu, typically found on native trees and shrubs in mountainous areas between 300-600 meters elevation. The species requires intact forest canopy and native vegetation for feeding and reproduction, making it highly dependent on undisturbed native Hawaiian ecosystems.
