Description complète des menacesTexte détaillé évaluation IUCNExpert
In times of famine, the stems have reportedly been used for food in Zanzibar, although it is more likely the seeds that are used, as is the case in northern Kenya (the central pith of the stem and the endosperm from the seeds is used to prepare a starchy form of bread). This species like all cycads is highly sought after in the horticulture trade. In addition, some plants are removed from the wild and sold to local hotel developers.

It has been recorded from a number of protected areas including: Jozani Forest Reserve on Zanzibar, Saadani National Park, one locality within Gendagenda South Forest Reserve, and one locality within Amani Nature Forest Reserve (all Tanzania); and two localities within Arabuko Sokoke Forest Reserve (Kenya). Plants are also found in Boni National Reserve, Kenya. This species is listed in CITES Appendix I and is well represented in botanical gardens and private collections worldwide. An education and awareness programme as well as the long-term monitoring of populations will support the conservation of this species.
