|Population:||The estimated population size of E. humilis is 4,500-10,000 mature individuals. The habitat of this species has been transformed through pine and eucalypt plantations that now occupy approximately 30% of its original habitat.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||This species grows in subalpine grassland, on slopes on sandy soils over sandstones and are often wedged between sandstone rocks. Populations are mostly found on east and northeast facing slopes. Heavy rains and dense mists favour coning.|
|Major Threat(s):||This species is threatened by the lack of natural fires in vast managed plantations and this possibly suppresses coning frequency. Many plants have also been removed for ornamental purposes.|
|Conservation Actions:||This species is listed on Appendix I of the CITES Appendices. Populations are protected in the Mondi Cycad Reserve, Makobulaan Nature Reserve, Wonderkloof Nature Reserve, Buffelskloof Private Nature Reserve, Mbesan Natural Heritage Site and the Coetzeestroom Conservation area.|
