Aloinopsis lodewykii

Assessor: Sarah Schumann

Sensitive in 2010
No
Family
Aizoaceae
Reason for the sensitivity status
This species and others of the genus were among those targeted and confiscated during a criminal prosecution of illegal plant collecting. This genus is in demand and of popular interest in international horticultural trade. Other species of this genus are threatened with illegal removal of wild individuals. As this taxon does not have a vulnerable population size, recruitment and recovery from harvesting may be possible.
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

According to the SANBI Red List Assessment, this species is of Least Concern as it is a range-restricted, fairly common and not thought to be threatened (von Staden, 2016). (von Staden, 2016). This genus is in demand and of popular interest in international horticultural trade, as indicated by several online marketplace, e-commerce and auction sites. Other species of this genus are threatened with illegal removal of wild individuals (Swart et al. 2015; Duncan et al. 2006; Cousins & Witowski, 2012). This species and others of the genus were among those targeted and confiscated during a criminal prosecution of illegal plant collecting (Confiscation Lists (2018-2022) provided by Cape Nature, SANBI Karoo Desert Botanical Garden and Kirstenbosch Botanical Garden). This suggests that this species and genus may be targeted and 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

This species has an extent of occurrence of 3343 km² and is thought to be fairly common (von Staden, 2016). Further specific population data on this species is not available.

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

Specific population data on this species is not available and so although this species is known to be exploited, regeneration potential cannot be deduced. However this species as this species is of Least Concern and not thought to be threatened (von Staden, 2016), were exploitation to occur recruitment and recovery may be possible.
