Haworthiopsis granulata

Assessor: Sarah Schumann

Sensitive in 2010
No
Family
Asphodelaceae
Reason for the sensitivity status
This taxon is known to be wild collected for the horticultural trade to a minor extent. Several others of the genus are known to be targeted, exploited and illegally removed from the wild, causing population decline. Evidence shows that the Haworthiopsis genus is in demand in international horticultural trade. As this taxon is widespread with insignificant exploitation, 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 widespread and not thought to be threatened (von Staden, 2014). This taxon is known to be collected from the wild for the horticultural trade to a minor extent (S. Molteno, personal communication, 12 August 2022). Several others of the genus were among those targeted and confiscated during recent criminal prosecutions of illegal plant collecting (Confiscation Lists (2019-2022) provided by Cape Nature, SANBI Kirstenbosch Botanical Garden and SANBI Karoo Desert Botanic Garden). This genus is currently in demand and of popular interest in horticultural trade, as indicated by several online marketplace, e-commerce and auction sites.

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 taxon is known from 13 subpopulations  (S. Molteno, personal communication, 12 August 2022).

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

As this taxon is widespread, does not have a vulnerable population size, and exploitation is insignificant exploitation, recruitment and recovery from harvesting may be possible.
