Boninena ogasawarae

Unknown

Overview

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

Boninena ogasawarae faces severe threats from habitat destruction caused by invasive plant species that alter the native forest understory where this endemic land snail resides. The introduction of non-native predators, particularly flatworms and other invasive mollusks, has significantly reduced population numbers across its limited range on the Ogasawara Islands. Climate change poses an additional threat through altered precipitation patterns that affect the humid microhabitats essential for this species' survival.

Threat summary

Habitat

This endemic land snail inhabits the humid understory of native subtropical forests on the Ogasawara Islands, particularly favoring areas with dense leaf litter and fallen logs. It requires consistently moist microhabitats with stable temperature and humidity conditions found in undisturbed forest environments.
