État de la populationTexte officiel évaluation IUCNExpert
The one subpopulation visited in 2001 had 300 plants. This was until recently one large contiguous population but is now fragmented. With Ceratozamia becerrae now considered a synonym of C. zoquorum, the population is estimated to be about 650-700 plants.

Description complète des menacesTexte détaillé évaluation IUCNExpert
The population is affected by habitat destruction due to agricultural expansion (cattle pastures, corn and coffee plantations). Forest fires have also had a significant effect on the wild subpopulations. There may also be some decline due to collecting. Those subpopulations that were previously known as Ceratozamia becerrae grow on steep limestone karst formations and this habitat is under threat from cement makers who mine and grind the limestone for concrete manufacture.
