État de la populationExpert
The population size of Encephalartos nubimontanus was originally estimated to be 50-100 mature individuals, but the known subpopulations were extirpated by collectors. Surveys of known areas of distribution in 2004 failed to reveal any plants and it was therefore classified as Extinct in the Wild. There have been several unconfirmed reports of possible additional plants in the wild but these have not been validated - the species can be confused with other cycad taxa that occur in the region. Despite requests for any additional information on previously undocumented subpopulations no new information has been provided for over 10 years.
