Donella ambrensis

Stable

Overview

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

Donella ambrensis faces significant pressure from habitat degradation in Madagascar's remaining forest fragments, where deforestation and agricultural expansion continue to reduce suitable microhabitats. The species' restricted range makes it particularly vulnerable to localized disturbances, while collection pressure for the shell trade poses an additional threat to remaining populations.
