Tabernaemontana ovalifolia

Unknown

Overview

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

Tabernaemontana ovalifolia faces severe pressure from deforestation and agricultural expansion across its limited range in Madagascar's eastern rainforests. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation, while slash-and-burn agriculture continues to reduce the quality of remaining forest patches. Collection pressure for traditional medicinal uses compounds these threats, as the species is valued locally for its alkaloid-rich bark and latex.
