Use and Trade: In Honduras, Dioon mejiae (called teucinte by the local inhabitants) seeds are ground and eaten.

Threats [top]

Major Threat(s): This species' biggest threat comes from habitat destruction as a result of the conversion of habitat to farmland and to a lesser extent the effects of logging and road-building on the habitat.

Conservation Actions [top]

Conservation Actions: This species is listed on Appendix II of the CITES Appendices. This species has important cultural value and is hence protected by local inhabitants.
