État de la populationTexte officiel évaluation IUCNExpert
There are no population estimates available for this species. However, the current population trend and number of mature individuals are inferred to be decreasing due to habitat loss and over harvesting of tubers from the wild.

Description complète des menacesTexte détaillé évaluation IUCNExpert
The restricted distribution places Dioscorea comorensis under threat from stochastic events in addition to deforestation and over-extraction (Wilkin et al. 2007).
