Encephalartos lanatus

Assessor: Sarah Schumann

Sensitive in 2010
No
Family
Zamiaceae
Reason for the sensitivity status
This taxon is deemed not sensitive. Evidence shows that the Encephalartos genus is in high demand in international trade for ornamental and horticultural purposes as well as local medicinal purposes. This species is not known to be exploited and targeted with illegal harvesting of wild individuals and has a large population size.
Exploitation extent
Uncertain - No data exists yet showing that this species is exploited in the wild, however it has one or more relatives or look-alike species (found in South Africa or globally) that are known to be utilised. This species has a similar life form or other relevant traits to its exploited relative(s), making it highly likely that it would be exploited for the same purposes.
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 of Least Concern as it is mostly threatened by habitat loss and is not a popular species for trade as it is sensitive to disturbance and transplanting (Donaldson 2009). 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, artificial propagation and botanical garden purposes. Sourced from artificial propagation, and taken from the wild.

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 70 000-80 000 mature individuals remaining in the wild (Donaldson 2010). The species has a restricted range with highly fragmented subpopulations. Extent of occurrence is 1 100 km² and area of occupancy is 100 km² (Donaldson 2009). The species is found in two private nature reserves and a World Heritage Site.

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.
Regeneration potential
This species has a slow population growth rate, or the growth rate varies depending on habitat, and there is a poor chance the wild populations will recover from exploitation OR a collector might feasibly harvest the entire extant population removing the chance of subsequent recruitment.
Justification and references

This species is abundant however subpopulations are highly fragmented and two subpopulations are threatened which could lead to population decline (Donaldson 2009; Golding & Hurter 2003). If exploitation were to occur, recruitment and recovery may be poor.
