Calyptrochilum aurantiacum

The habitat of Ossiculum aurantiacum  is threatened by human activities such as timber exploitation (north of the Banyang Mbo Wildlife Sanctuary), cocoa, plantain and banana plantations (Mungo River Forest Reserve) and shifting agriculture at small-scale and oil palm plantations (east of the Banyang Mbo Wildlife Sanctuary).

Ossiculum aurantiacum occurs within two protected areas: the Banyang Mbo Wildlife Sanctuary in Cameroon and the Odzala National Park in Republic of the Congo. The species habitat there appears well managed. Ossiculum aurantiacum is also in cultivation in the Yaoundé shadehouse. However, urgent action is required to address the issues of timber extraction from the Mungo River area, and to protect the existing forest reserves from illegal encroachment of agricultural activity. Intensive orchid survey should be carried out for the CRES Orchid Programme at Mungo and other nearby lowland areas, such as the adjacent Loum Forest Reserve.
