Partulina mighelsiana

Unknown

Overview

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

Partulina mighelsiana faces severe population decline primarily due to predation by introduced carnivorous snails, particularly Euglandina rosea, which was deliberately introduced to control agricultural pests but devastated native Hawaiian tree 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 these arboreal snails require for survival.

Threat summary

Habitat

This endemic Hawaiian tree snail inhabits native montane forests, particularly in areas with dense canopy cover that maintains the cool, humid microclimate essential for its survival. It is typically found on native trees and shrubs in elevations ranging from 300 to 1,200 meters, where it feeds on fungal films and biofilms on leaf surfaces.

Frequently asked questions

Why is Partulina mighelsiana classified as Endangered?
Partulina mighelsiana 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 mighelsiana faces severe population decline primarily due to predation by introduced carnivorous snails, particularly Euglandina rosea, which was deliberately introduced to control agricultural pests but devastated native Hawaiian tree 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 these arboreal snails require for survival.
Where does Partulina mighelsiana live?
Partulina mighelsiana 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 mighelsiana?
The main threats to Partulina mighelsiana 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.
