Euphorbia globosa

Assessor: Sarah Schumann

Sensitive in 2010
Yes
Family
Euphorbiaceae
Reason for the sensitivity status
This species is threatened by harvesting of wild individuals. There have been several recorded confiscations of species of the Euphorbia 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 makes this species vulnerable to further population loss. Recruitment and recovery from harvesting may be poor. Releasing data on this species could 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 SANBI Red List Assessment, this species is Endangered as it occurs at less than five remaining locations due to ongoing habitat loss, degradation and harvesting of wild individuals (Victor & Dold, 2019). This genus is currently 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 Euphorbia species from illegal collection (Confiscation List (2018-2021) provided by Cape Nature, SANParks Sendelingsdrift Botanic Garden, Karoo Desert Botanical Garden, and Kirstenbosch Botanical Garden). This suggests that this genus is being targeted and that this species 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 occurs at less than five remaining locations (Victor & Dold, 2019).

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 makes this species vulnerable to further population loss. Recruitment and recovery from harvesting may be poor.
