État de la populationTexte officiel évaluation IUCNExpert

Although once regarded as a relatively abundant cycad, populations have declined across its range. The population size of Encephalartos paucidentatus was originally estimated to be 8,000-12,000 mature individuals but recent estimates suggest that it is probably much lower (3,000-5,000). Further research must be prioritised as the numbers may even be a lot lower than the current estimates.
