Adromischus maximus

Assessor: Sarah Schumann

Sensitive in 2010
No
Family
Crassulaceae
Reason for the sensitivity status
This species and several others of the Adromischus genus have been illegal harvested. This genus is in demand and of popular interest in international horticultural trade. Few known subpopulations 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
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 Rare as it is known from less than 10 subpopulations and is not thought to be threatened (Helme & Victor, 2007). This genus is in demand and of popular interest in international horticultural trade, as indicated by several online marketplace, e-commerce and auction sites. Recently this species and several others of the Adromischus genus have been illegal harvested (Confiscation List (2018-2021) provided by Cape Nature SANBI Kirstenbosch Botanical Garden and Karoo Desert Botanical Garden). This suggests that this genus is being targeted and that this species may be 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 taxon is known from less than 10 subpopulations (Helme & Victor, 2007).

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

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