Conophytum pium

Assessor: Sarah Schumann

Sensitive in 2010
Reason for the sensitivity status
This species and several others of the genus are known to be targeted, exploited and illegally removed from the wild, causing population decline. Evidence shows that the Conophytum genus is in high demand in international horticultural trade. One known location and a small population size makes this species highly vulnerable to population loss and is threatened with over-collection. Releasing data on this species can exacerbate threat and vulnerability.
This species is extremely rare in the wild and is known to be exploited, utilised or traded. The localities of remaining populations need to be protected to avoid any further exploitation, which is likely to drive it to extinction.
Exploitation extent
Significant - wild individuals of the species are known to be exploited, collected, traded or utilized in a targeted manner, and utilisation is widespread, affects the majority of wild populations and/or is causing rapid decline of the wild population.
Justification and references

According to the IUCN Red List Assessment, this species is Critically Endangered as it is known from a single location that is experiencing population decline due to the threat of illegal collection of mature individuals for the international trade in ornamental succulents (Young, 2022). Collecting pressure is likely to increase in the future as this species is highly sought after by collectors as well the number of species and volume of plants that have been targeted within the genus having increased since 2019 (Young, 2022). As of 2019, this genus has become popular in trade and there is a high demand from international and domestic horticultural markets for wild collected plants as indicated by media, police reports and several online marketplace, e-commerce, and auction sites (Friedman, 2021; Tshuma, 2021; Trenchard, 2021; Hyman, 2020; Young, 2020). Plants of this genus were among those targeted and/or confiscated during recent criminal prosecutions of illegal plant collecting (Majikela, 2020; Myburgh, 2021). There has been several recorded confiscations of the species and others of the genus from illegal plant collection (Confiscation Lists (2019-2021) provided by Cape Nature, SANBI Karoo Desert National Botanical Garden, SANBI Kirstenbosch Botanical Garden, SANParks Sendelingsdrift Botanic Garden and the Department of Forestry, Fisheries and the Environment). Rare Conophytum species remain potentially threatened by collecting (Young et al. 2015). This suggests that this genus is being targeted and that this species is threatened.

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 species has an extent of occurrence of 4 km², is known from one location and has an estimated population size of less 1,500 mature individuals (Young, 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.
Justification and references

Whole individuals are recorded in confiscations.

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

A single known location with existing threat of exploitation (Young, 2022), places the persistence of this species at risk. Regeneration potential for the vast majority of the Conophytum genus is very poor as recruitment is low and dependent on successive, appropriate weather conditions. Seeds are not known to disperse. Regeneration will take decades. (Young, personal communication 2021, 5 October)
