Calpocalyx cauliflorus

Unknown

Overview

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

Calpocalyx cauliflorus faces severe pressure from deforestation and agricultural expansion across its limited range in West and Central Africa. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation, as remaining forest patches become increasingly isolated. Logging activities targeting valuable timber species also degrade the understory environment where this shrub thrives, while slash-and-burn agriculture continues to reduce suitable habitat.

Threat summary
