Oxandra unibracteata

Unknown

Overview

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

Oxandra unibracteata faces severe population decline primarily due to deforestation and agricultural expansion within its extremely limited range in the Colombian Andes. The species' restriction to a single locality makes it exceptionally vulnerable to habitat conversion, with coffee cultivation and cattle ranching representing the most immediate threats to remaining forest fragments.
