Boninosuccinea ogasawarae

Unknown

Overview

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

Boninosuccinea ogasawarae faces severe pressure from invasive species, particularly the introduced flatworm Platydemus manokwari, which preys directly on native land snails. Habitat degradation from invasive plants and human development on the Ogasawara Islands has reduced available forest floor microhabitats essential for this species' survival. Climate change poses additional risks through altered precipitation patterns that affect the humid conditions required by this terrestrial gastropod.

Threat summary

Habitat

This endemic land snail inhabits the humid forest floors and leaf litter of the Ogasawara Islands' native forests, particularly in areas with dense vegetation cover that maintains consistent moisture levels. The species requires specific microhabitat conditions found in undisturbed forest ecosystems with rich organic matter and stable humidity.
