Polyscias aemiliguineae

Unknown

Overview

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

Polyscias aemiliguineae faces severe threats from deforestation and habitat conversion in its limited range within Madagascar's eastern rainforests. The species' extremely restricted distribution makes it particularly vulnerable to localized disturbances, including slash-and-burn agriculture and logging activities. Climate change poses an additional threat through altered precipitation patterns that could affect the humid forest conditions this endemic tree requires.
