Partulina perdix

Unknown

Overview

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

Partulina perdix faces severe threats from habitat destruction as native Hawaiian forests are cleared for agriculture and development. 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) and various ant species, has caused dramatic population declines across its range.

Threat summary

Habitat

This endemic Hawaiian tree snail inhabits native mesic and wet forests on Oahu, typically found on native trees and shrubs in the forest canopy and understory. It requires intact native forest ecosystems with high humidity and diverse native plant communities that provide both food sources and suitable microhabitats.
