Partulina physa

Unknown

Overview

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

Partulina physa faces severe threats from habitat destruction as native Hawaiian forests are cleared for development and agriculture. Invasive plant species alter the forest understory composition, reducing suitable microhabitats for this endemic tree snail. Predation by introduced species, particularly the rosy wolf snail (Euglandina rosea), has devastated populations across its range. Climate change compounds these pressures by altering moisture regimes essential for this species' survival.

Threat summary

Habitat

Partulina physa inhabits native Hawaiian montane forests, particularly areas with dense canopy cover that maintain high humidity levels. This arboreal species requires specific moisture conditions and native vegetation structure found in undisturbed forest ecosystems.

Why is Partulina physa classified as Endangered?
Partulina physa is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Partulina physa faces severe threats from habitat destruction as native Hawaiian forests are cleared for development and agriculture. Invasive plant species alter the forest understory composition, reducing suitable microhabitats for this endemic tree snail. Predation by introduced species, particularly the rosy wolf snail (Euglandina rosea), has devastated populations across its range. Climate change compounds these pressures by altering moisture regimes essential for this species' survival.
Where does Partulina physa live?
