État de la populationTexte officiel évaluation IUCNExpert

The overall population size is estimated to be at least 20,000 individuals and the population appears to be stable. The Channel Point subpopulation of Cycas canalis has a small proportion (<5%) of adults greater than 1 m tall. Seedlings are few and many apparently juvenile plants are regrowth from old bases or root stock. The remaining subpopulations appear to have a more balanced population structure with a larger percentage of adults.

Description complète des menacesTexte détaillé évaluation IUCNExpert

Large areas of the Channel Point subpopulation have been cleared for agriculture and there is a potential that additional areas will be cleared for agriculture and tourist development. Frequent fire appears to also be a threat to reproduction in the Channel Point subpopulation. In the remaining subpopulations fire and land clearing are possible threats, with extensive clearing for agricultural proposed for the Daly Basin. As with some species within this genus, it is also susceptible to over collecting for ornamental purposes.
