Partulina redfieldi

Unknown

Overview

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

Partulina redfieldi faces severe population decline primarily due to predation by introduced carnivorous snails, particularly Euglandina rosea, which was deliberately introduced to Hawaiian islands for biological control but devastated native snail populations. Habitat degradation from invasive plant species and feral ungulates has further reduced suitable forest environments, while climate change threatens the cool, moist conditions this species requires for survival.

Threat summary

Habitat

Partulina redfieldi inhabits native Hawaiian montane forests, particularly areas with dense canopy cover that maintain cool, humid microclimates. The species requires specific moisture conditions and native vegetation, typically found in undisturbed forest areas with abundant leaf litter and decaying organic matter.
