Partulina dubia
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Partulina dubia faces severe threats from invasive predatory species, particularly the rosy wolf snail (Euglandina rosea) and various flatworms that actively hunt native Hawaiian tree snails. Habitat degradation from feral ungulates and invasive plant species has further reduced suitable forest environments. The species' extremely limited range and small population size make it highly vulnerable to stochastic events and local extinctions.
Habitat
Partulina dubia inhabits native montane forests on the Hawaiian island of Oahu, typically found on native trees and shrubs in mesic to wet forest zones. The species requires intact forest canopy and native vegetation for both shelter and the fungal food sources that grow on decaying plant matter.
