Description complète des menacesTexte détaillé évaluation IUCNExpert

This species has been affected by habitat destruction as a result of road building and land clearance for agricultural practices. This species is very rare in the wild although quite common in cultivation. It may be extinct in Jamaica and is almost extinct in Puerto Rico as a result of habitat destruction and to some extent by over collection by commercial growers, rather than by cycad collectors.
