Reason for the sensitivity status
There have been several recorded confiscations of this species and others of the Anacampseros genus from illegal collection. This genus is in demand and of popular interest in international horticultural trade. Few known locations of occurrence with existing threats causing population decline makes this subspecies vulnerable to further population loss. Recruitment and recovery from harvesting may be poor. Releasing data on this subspecies could exacerbate threat and vulnerability.
This species is either similar to another sensitive species or belongs to a group containing sensitive species, and is extremely rare in the wild. The localities of wild populations need to be protected to avoid loss to exploitation, which, due to its rarity, could drive the species to extinction within a very short time.
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 subspecies is Vulnerable as it is experiencing population decline due to ongoing habitat degradation and loss (von Staden & de Castro, 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. Plants of this genus were among those targeted and/or confiscated during criminal prosecutions of illegal plant collecting. There have been several recorded confiscations of this species and others of the Anacampseros genus from illegal collection (Confiscation List (2018-2022) provided by Cape Nature, SANParks Sendelingsdrift Botanic Garden, Karoo Desert and Kirstenboosch Botanic Gardens). This suggests that this genus is being targeted and that this subspecies may be at risk.

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
This taxon has an extent of occurrence of 1432 km² and is known from seven locations that are declining (von Staden & de Castro, 2016).

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 slow population growth rate, or the growth rate varies depending on habitat, and there is a poor chance the wild populations will recover from exploitation OR a collector might feasibly harvest the entire extant population removing the chance of subsequent recruitment.
Justification and references
Few known locations of occurrence with existing threats causing population decline makes this species vulnerable to further population loss.
