État de la populationTexte officiel évaluation IUCNExpert
The population of Bulbophyllum ankaizinense is currently thought to be decreasing since 19 occurrences on the mine footprint have been extirpated as well as two occurrences in unprotected forests. The number of mature individuals cannot be estimated since the species is an epiphyte growing on lower branches of trees in humid forests.
