Justification
This species is assessed as Critically Endangered. It has declined across its range and spectacular declines have been recorded for subpopulations in Kaapsehoop and Mariepskop (no longer present at this site), due to poaching, and subpopulations in Eswatini have also disappeared. All subpopulations appear to be affected by a fungal infection of the female cones, which destroys all the seeds. Overall the population has declined by more than 97% since the 1970s. This is less than one generation, but further extrapolation is difficult and so this is a minimum decline for the past three generations. The small number of plants remaining (estimated as 6-11), dispersed across several sites, suggests that the species will not be able to reproduce naturally and is functionally extinct in the wild.
Distribution
Endemism
Not endemic to South Africa
Provincial distribution
Eastern Cape, KwaZulu-Natal, Limpopo, Mpumalanga
Range
Historically, this species used to occur in Mpumalanga, KwaZulu-Natal, and the Eastern Cape provinces, South Africa as well as in Eswatini, but today it only occurs in Mpumalanga within the Kaapsehoop mountain range with an isolated colony occurring further north. The subpopulations in Eswatini as well as the Blyderivierspoort Nature Reserve in Mpumalanga, KwaZulu Natal, Limpopo, and the Eastern Cape provinces are all extinct due to poaching. It was originally recorded to occur from 950 up to 1,800 m asl.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Northern Escarpment Quartzite Sourveld
Description
This species occurs in grassland or low shrubs on steep rocky slopes. Most localities are high altitude sites (1,300 to 1,500 m), with frequent mists. Like many other Encephalartos species, E. laevifolius appears to be adapted to a three to five year burning cycle. Plants grow in full sunlight in grassland or scrub.
Threats
The most drastic effect has been by over-collecting for ornamental purposes and this is responsible for >97% decline since the 1970s. Signs of stem harvesting for traditional medicine have been observed although this has not been quantified. Evidence of plant pathogens have been reported since the 1980s with the infection occurring in female cones and resulting in abortion of cones. There is a limited threat associated with habitat loss due to timber plantations and alien invasive plants.
Population

Available data suggest that there are fewer than 50 plants remaining in the wild and possibly even less than that. The population originally consisted of a relatively large subpopulation in the Kaapsehoop area (early estimates of 1,700 plants) with smaller subpopulations occurring at Mariepskop (75 stems counted in 1970), Eswatini (25 plants) and KwaZulu Natal. Population surveys in 1990 (K. Zunckel MSc) counted 578 plants at Kaapsehoop, 182 on nearby farms and only 55 stems at Mariepskop. Zunckel (1990) estimated that poaching was resulting in the loss of one plant a month at the more accessible sites. By 2016, it was estimated that the population had declined by 97% due to poaching to supply the horticultural trade and private collections (Scientific Authority 2016). The subpopulations in KwaZulu Natal, Eswatini and Mariepskop had by then all been extirpated. Surveys underway in 2020-2021 detected only a single plant in the Kaapsehoop area (W. van Staden pers. comm.) and there is one other known site with 5-10 mature plants. Given the extremely low numbers and wide separation of the surviving plants, it should be regarded as functionally extinct in the Wild.
