État de la populationTexte officiel évaluation IUCNExpert
This species is known from three sub-populations at two localities. Visits to these subpopulations have recorded declines in habitat and population numbers exceeding 50% overall. A study of modelled distribution range and overlays of intact habitat showed a 36% decline in habitat across this much greater area.

Description complète des menacesTexte détaillé évaluation IUCNExpert
Ceratozamia sabatoi is only known from two localities. The status of the high elevation locality in Hidalgo appears to be critical. It was transformed years ago for agriculture and although new habitat loss appears to have slowed, surveys indicate an ongoing decline in the number of plants, possibly due to grazing. As with most species within this genus, it is susceptible to over collecting for ornamental purposes.
