Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Achatinella decipiens 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 arboreal snail's survival. Climate change poses an additional threat through altered precipitation patterns that affect the moisture-dependent microhabitats these snails require.

Threat summary

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 high humidity environments with dense canopy cover that maintains the moist microhabitats essential for feeding on fungal biofilms growing on leaf surfaces.
