Encephalartos ferox

Assessor: Sarah Schumann

Sensitive in 2010
No
Family
Zamiaceae
Reason for the sensitivity status
This taxon is deemed not sensitive. Although this species is known to be exploited and targeted, population loss from illegal harvesting is small. The population size is not small and there is regeneration potential due to possible recruitment from the many remaining individuals in the wild.
Exploitation extent
Small or insignificant - wild individuals of the species are known to be exploited, collected, traded or utilized in a targeted manner, but utilisation is localised and/or affects only a small proportion of the wild population.
Justification and references

All South African cycads as well as this species is included in Appendix I of the CITES Convention which lists all species threatened with extinction that are, or may be affected by trade. According to the SANBI Red List Assessment, this species is Near Threatened as it is threatened by illegal over-collecting for ornamental purposes and habitat loss (Donaldson 2012; Donaldson 2003). This is a very widespread species with only a small fraction of the overall population occurring in South Africa whereby 10-15 % of its population is likely to decline in the next two generationsas per the unpublished Red List Assessment. (Bösenberg. DW, personal communication 2021, 1 December). Cycad species are in trade demand and at risk from illegal collection (Smith 2014; Yeld 2014). Studies present strong evidence of ongoing and accelerating rates of decline in most cycad species due mainly to illegal removal (Okubamichael et al. 2016; Cousins & Witkowski 2017). The CITES Trade Database has recorded the trade of the species from 1979-2019 for commercial, personal, scientific, travelling exhibition and botanical garden purposes. Sourced from artificial propagation, taken from the wild, and confiscated or seized. Research shows that this species is illegally harvested for medicinal trade and has been identified for sale at two traditional medicine markets in South Africa (Williamson et al. 2016).

Population vulnerability
Population is not vulnerable: size is > 2500 mature individuals, AND the number of known subpopulations is > 5 AND range > 100km2
Justification and references

According to the IUCN Red List, there are 100 000 mature individuals remaining in the wild (Donaldson 2010). Many large subpopulations occur (Donaldson 2012).

Targeted demographics
Mature (breeding) individuals are killed, significantly weakened or are permanently removed from the wild, OR immature individuals are targeted and this significantly impacts mature (breeding) individuals.
Justification and references

The CITES Trade Database has recorded the trade of live individuals and seeds. Collection of wild individuals has caused population decline  (Donaldson 2012; Donaldson 2003).

Regeneration potential
This species has a fast population growth rate, and there is a good chance the wild populations will recover from exploitation.
Justification and references

As this species is widespread and occurring outside of South Africa too, recruitment and recovery from exploitation may be possible (Bösenberg. DW, personal communication 2021, 1 December).
