Argyroderma fissum

Assessor: Sarah Schumann

Sensitive in 2010
No
Family
Aizoaceae
Reason for the sensitivity status
There have been several recorded confiscations of this species and others of the Argyroderma genus from illegal collection. This genus is in demand and of popular interest in international horticultural trade. 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 (Burgoyne, 2006). This genus is in demand and of popular interest in 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 criminal prosecutions of illegal plant collecting. There have been several recorded confiscations of this species and others of the Argyroderma genus from illegal collection (Confiscation List (2020-2022) provided by Cape Nature, Kirstenbosch Botanical Garden and SANparks Sendlingsdrift). This suggests that this genus is being targeted and that this species may be at risk.

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

Whole individuals are recorded in confiscations.

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 taxon does not have a vulnerable population size, recruitment and recovery from harvesting may be possible.
