Encephalartos latifrons

Assessor: Sarah Schumann

Sensitive in 2010
Yes
Family
Zamiaceae
Reason for the sensitivity status
This taxon is deemed not sensitive. Evidence shows that this species and others of the Encephalartos genus is in high demand in international trade for ornamental and horticultural purposes as well as local medicinal purposes. Although this species is known to be exploited and targeted with illegal harvesting of wild individuals causing population decline, it is under a restoration program to increase its population size. Recovery from exploitation via the recruitment of wild individuals is possible.
Exploitation extent
Significant - wild individuals of the species are known to be exploited, collected, traded or utilized in a targeted manner, and utilisation is widespread, affects the majority of wild populations and/or is causing rapid decline 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 Critically Endangered as it is threatened by over-collecting for ornamental purposes, reproductive failure and land cover change, causing the population to decline (Donaldson 2009; Donaldson 2003). This species is scarce and a highly valued species in cycad trade (Donaldson 2009). Studies present strong evidence of ongoing and accelerating rates of decline in most cycad species due mainly to illegal removal and this is especially evident with endangered and critically endangered Encephalartos species (Okubamichael et al. 2016; Cousins & Witkowski 2017; Smith 2014). Due to its conservation concern status, this species is particularly at risk from trade. In 2014, E. latifrons individuals in the Kirstenbosch Botanical Garden were stolen (Yeld 2014). This species has a low and decreasing remaining population and cannot sustain ongoing removal from the wild (CITES 2003). The CITES Trade Database has recorded the trade of the species from 1980-2019 for commercial, personal, scientific, artificial propagation and botanical garden purposes. Sourced from artificial propagation, taken from the wild.

Population vulnerability
Population is vulnerable: size is <= 2500 mature individuals OR the number of known subpopulations is <= 5 OR range is <= 100km2 OR species at risk of localised extinctions
Justification and references

According to the IUCN Red List, there are between 60-100 mature individuals remaining in the wild and the area of occupancy is an estimated 9 km² (Donaldson 2010; Donaldson 2009). Subpopulations contain 20 individuals which is too low for pollinator support and so too low for recruitment (Donaldson 2009).

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, stems and seeds. Mature individuals are removed from the wild and its natural pollinators are likely to have gone extinct and with the result that recently no viable seeds have been recorded (Donaldson 2009).

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

Currently, there is an active restoration program at a selected site and this is likely to expand to other sites within the original distribution range of this species (Bösenberg. DW, personal communication 2021, 1 December).
