|Scientific Name:||Encephalartos dolomiticus Lavranos & D.L.Goode|
Encephalartos verrucosus Robbertse, Vorster & S.van der Westhuizen
|Red List Category & Criteria:||Critically Endangered A2d; C1 ver 3.1|
|Reviewer(s):||Agenbag, L. & Bösenberg, J.D.|
Based on numbers in collections and ongoing decline in the wild, it is estimated that >80% of the plants have been removed from the wild in the past 90 years (three generations). The small overall population size and ongoing decline of ca. 30% over the next 30 years (one generation). Meeting both these requirements means that this species qualifies for listing as Critically Endangered under criteria A2 and C1.
|Previously published Red List assessments:|

|Population:||158 plants were counted in helicopter surveys in 1993 and 151 plants in 2004. The latter included 17 newly discovered plants and implies a decline from 158 to 134 plants for the remainder (9% decline over 10 years).|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||This species occurs on grassland on shallow soils over dolomite ridges.|
|Generation Length (years):||70|
|Major Threat(s):||Illegal collection from wild populations has had a drastic effect on the number of plants in the wild. This may prevent reproduction from taking place.|
|Conservation Actions:||This species is listed on Appendix I of the CITES Appendices. This species possibly occurs in the Legalameetse Nature Reserve.|
