Reason for the sensitivity status
It is thought that demand for collection is unlikely and that populations are mostly in secure areas. Several others of the genus are known to be targeted, exploited and illegally removed from the wild, causing population decline. Evidence shows that the pelargonium genus is in demand in international horticultural trade. Although the species is thought to be protected, the genus is known to be targeted and with a small population size that is experiencing other threat, it is vulnerable to population loss. Releasing data on this species 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 species is Endangered as it is has experienced a 60-80% population reduction due to habitat loss (Helme et al. 2012). It is thought that demand for collection is unlikely and that populations are mostly in secure areas (van der Walt, R personal communication, 12 August 2022). 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 recent criminal prosecutions of illegal plant collecting. There have been several recorded confiscations of species of the Pelargonium genus from illegal collection (Confiscation List (2018-2021) provided by Cape Nature, SANParks Sendelingsdrift Botanic Garden, SANBI Kirstenbosch Botanical Garden and Karoo Desert Botanic Garden).

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 population is severely fragmented and remains at 6-10 of its original locations with a population reduction of between 60-80% (Helme et al. 2012).

Targeted demographics
Unknown.
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
Fragmented populations with few remaining locations of occurrence experiencing existing threat make this species vulnerable to population loss. Were exploitation to also occur, recruitment and recovery may be poor.
