Dioon edule Lindl. var. latipinnium Dyer
|Red List Category & Criteria:||Least Concern ver 3.1|
|Reviewer(s):||Donaldson, J.S. & Bösenberg, J.D.|
Recent surveys in Honduras indicate that there are many large and healthy subpopulations with little evidence of decline despite use by local people.
|Previously published Red List assessments:|
|Range Description:||This species occurs in the states of Colon, Olancho and Yoro of Honduras.|
Native:Honduras (Honduras (mainland))
|Range Map:||Click here to open the map viewer and explore range.|
|Population:||The populations of Dioon mejiae have been conservatively estimated to total more than 600,000 wild plants. This includes two “super-populations”, each containing more than 100,000 plants.|
|Current Population Trend:||Stable|
|Habitat and Ecology:||This species is typically an understorey component of semi-deciduous tropical rain forest and is found on steep slopes and in canyons, but also grows on flat terrain. Some populations thrive in sandy soil or sandy to clayey alluvial deposits, while others grow in loamy, limestone-derived soils; in soils weathered from metamorphics (schists, gneisses); etc.|
|Generation Length (years):||500|
|Use and Trade:||In Honduras, Dioon mejiae (called teucinte by the local inhabitants) seeds are ground and eaten.|
|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:||This species is listed on Appendix II of the CITES Appendices. This species has important cultural value and is hence protected by local inhabitants.|
