Eriospermum alcicorne

Assessor: Sarah Schumann

Sensitive in 2010
No
Family
Ruscaceae
Reason for the sensitivity status
Several species of the Eriospermum genus have been targeted by illegal harvesters. This species is in demand and of interest in the international horticultural trade. Plants of this genus were among those targeted and confiscated during criminal prosecutions of illegal plant collecting. As this species is thought to be of Least Concern, recruitment and recovery may be possible.
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

According to the SANBI Red List Assessment, this species is of Least Concern (Foden & Potter, 2006). This genus is in demand and of interest in the international horticultural trade, as indicated by several online marketplace, e-commerce and auction sites. Plants of this genus were among those targeted and confiscated during recent criminal prosecutions of illegal plant collecting (Confiscation Lists (2016-2021) provided by Cape Nature, SANBI Kirstenbosch Botanical Garden, SANBI Karoo Desert Botanic Garden, SANParks Sendelingsdrift Botanic Garden and Department of Forestry, Fisheries and the Environment). This suggests that this genus is being targeted and that this species may be at risk.

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

Population data on this species is not available but it is of Least Concern.

Targeted demographics
Unknown.
Regeneration potential
Unknown
Justification and references

Specific population data on this species is not available and so regeneration potential cannot be deduced. However as this species is thought to be of Least Concern, recruitment and recovery may be possible. Generally Eriospermums are long-lived, slow-growing tuberous genus that have a high regeneration rate for most species. Can form large local populations quite quickly but majority of species are rare in the landscape making them vulnerable to illegal collection. Species are usually locally abundant but multiplication can be slow and small. (van Jaarsveld. E, Helme. N & Peckover. R, personal communication 2021, 14 October)
