Aore Tree Snail

Partula auraniana

Unknown

Overview

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

Partula auraniana faces severe threats from invasive predatory snails, particularly Euglandina rosea, which were introduced to control agricultural pests but devastated native Partula populations across French Polynesia. Habitat degradation from human development and introduced plant species further fragments the remaining suitable forest areas. Climate change poses additional risks through altered precipitation patterns that affect the humid microhabitats essential for this species' survival.

Threat summary

Habitat

Partula auraniana inhabits humid tropical forests in the mountainous regions of Tahiti, French Polynesia, typically found on native vegetation in areas with consistent moisture and moderate temperatures. The species requires specific microhabitat conditions including adequate leaf litter and vegetation for feeding and shelter.

Aore Tree Snail 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. Partula auraniana faces severe threats from invasive predatory snails, particularly Euglandina rosea, which were introduced to control agricultural pests but devastated native Partula populations across French Polynesia. Habitat degradation from human development and introduced plant species further fragments the remaining suitable forest areas. Climate change poses additional risks through altered precipitation patterns that affect the humid microhabitats essential for this species' survival.
Where does Aore Tree Snail live?
Aore Tree Snail occurs in Vanuatu. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
