Partulina semicarinata

Unknown

Overview

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

Partulina semicarinata faces severe population decline primarily due to predation by introduced species, particularly the carnivorous snail Euglandina rosea and various flatworm species that were introduced to Hawaiian ecosystems. Habitat degradation from invasive plant species and feral ungulates has further reduced suitable native forest areas. Climate change poses an additional threat through altered precipitation patterns that affect the moist microhabitats essential for this endemic Hawaiian tree snail's survival.

Threat summary

Habitat

This endemic Hawaiian tree snail inhabits native mesic and wet forests on Oahu, typically found on native trees and shrubs in areas with consistent moisture and moderate temperatures. The species requires intact native forest canopy that maintains the humid microclimate conditions essential for its survival and reproduction.
