|Scientific Name:||Encephalartos mackenziei L.E.Newton|
|Red List Category & Criteria:||Near Threatened ver 3.1|
|Reviewer(s):||Agenbag, L. & Bösenberg, J.D.|
Would qualify as Endangered under criteria B1ab+2ab if there was any evidence of decline but the species occurs in a remote part of southern Sudan and there are no confirmed reports of decline in either the extent of habitat or number of individuals. There are alleged reports of plants being removed from the wild, these need to be investigated, and if found to be correct, the status of this species will need immediate revision.
