02Description

Species Profile

Bolawano (Osmoxylon simplicifolia) is a tropical tree species belonging to the Araliaceae family, characterized by its distinctive simple leaves and umbrella-like flower clusters. This medium-sized canopy tree plays a crucial ecological role in its native forest ecosystems by providing food resources for various wildlife species and contributing to forest structure and biodiversity.

Bolawano (Osmoxylon simplicifolia) faces severe population decline primarily due to extensive deforestation and habitat conversion for agriculture and development across its limited range in the Philippines. The species' restricted distribution makes it particularly vulnerable to localized habitat loss and fragmentation.
