État de la populationTexte officiel évaluation IUCNExpert
Approximately 10 mature individuals were seen from three trees and these are the only ones known of (M. Cheek pers. comm. 2017). Surveys in other surviving submontane forest fragments of the Bamenda Highlands carried out by British and Cameroonian scientists in recent years have not yet revealed further sites for this species (Onana and Cheek 2011).

Description complète des menacesTexte détaillé évaluation IUCNExpert
This species, currently, is known from only three trees. While efforts are made to protect forest by the Dom community, some tree-felling continues. Overall it is estimated that as much as 96.5% of the original montane (including submontane) forest of the Bamenda Highlands has been lost. GIS-based studies within another area of the Bamenda Highlands show that the loss of forest cover continues, with 25–30% lost in the area around Mt Oku between 1987–1995 (Onana and Cheek 2011).

Mesures de conservation recommandéesStratégies de conservation IUCNExpert
The Apicultural and Nature Conservation Organisation (ANCO), a non-governmental forest conservation organisation based in Bamenda, has alerted the population of Dom, which manages the forest fragment inhabited by Coleochloa domensis, to the existence of this rare species and its conservation importance. This needs to be followed up. Consideration should be given to seedbanking the species for long term protection, and to multiplying the species in a nursery to strengthen the wild population.
