Gastrocopta boninensis

Unknown

Overview

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

Gastrocopta boninensis faces severe habitat degradation on the Bonin Islands due to invasive plant species that alter native forest structure and soil composition. Development pressure and tourism infrastructure on these small oceanic islands further fragments the limited suitable habitat. The species' restricted range makes it particularly vulnerable to stochastic events and environmental changes that could rapidly affect the entire population.

Threat summary

Habitat

This endemic land snail inhabits native forest floors and leaf litter in the subtropical forests of the Bonin Islands (Ogasawara Islands), Japan. It requires moist microhabitats with specific soil conditions and native plant communities that provide appropriate calcium sources and shelter.
