Partulina variabilis

Unknown

Overview

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

Partulina variabilis faces severe population declines primarily due to habitat destruction from urban development and agricultural expansion across its Hawaiian range. Introduced predatory species, particularly the rosy wolf snail (Euglandina rosea), have devastated native snail populations throughout the Hawaiian Islands. Climate change compounds these pressures by altering moisture regimes essential for this species' survival in native forest ecosystems.

Threat summary

Habitat

This endemic Hawaiian tree snail inhabits native mesic and wet forests, typically found on native vegetation including koa and ohia trees. The species requires specific moisture conditions and depends on the native forest canopy structure for shelter and feeding opportunities.

Frequently asked questions

Why is Partulina variabilis classified as Endangered?
Partulina variabilis 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 variabilis faces severe population declines primarily due to habitat destruction from urban development and agricultural expansion across its Hawaiian range. Introduced predatory species, particularly the rosy wolf snail (Euglandina rosea), have devastated native snail populations throughout the Hawaiian Islands. Climate change compounds these pressures by altering moisture regimes essential for this species' survival in native forest ecosystems.
Where does Partulina variabilis live?
Partulina variabilis occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Partulina variabilis?
The main threats to Partulina variabilis are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
