État de la populationTexte officiel évaluation IUCNExpert
Estimations from 2003 put the total number of plants across the population at 300-500. Latest figures put it at 600-700 of which 300-350 would be considered as mature individuals.

Description complète des menacesTexte détaillé évaluation IUCNExpert
This species is affected by habitat destruction for agricultural purposes, too frequent fires, possible pollinator extinction, crop spraying, soil erosion and over-collecting for ornamental purposes.

Mesures de conservation recommandéesStratégies de conservation IUCNExpert
This species is listed in Appendix II of the CITES Appendices. Zamia inermis is known from only a single extant subpopulation that is severely threatened by fire, over collection, and apparently eradication of its pollinator as evidenced by its very low fertility in habitat as opposed to its high fertility in cultivation in botanical gardens. An education and awareness programme as well as the long-term monitoring of the population will support the conservation of this species.
