État de la populationExpert

The population of Beclardia grandiflora is currently thought to be decreasing since the species habitat is threatened. Moreover, the specimen taken on an individual within the footprint of a mining project undergoing intense human pressure such as forest clearing is now considered extirpated. The number of individual of B. grandiflora is not known and it is difficult to estimate since the species is an epiphyte.
