Vernonia unicata

Unknown

Overview

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

Vernonia unicata faces significant pressure from agricultural expansion and habitat conversion in its native range. Deforestation for crop cultivation and livestock grazing has fragmented its natural woodland habitats, while collection for traditional medicinal uses has reduced wild populations in accessible areas. Climate change poses an additional threat through altered precipitation patterns affecting the seasonal flowering cycles this species depends upon.

Threat summary

Habitat
