Adromischus montium-klinghardtii | SANBI Sensitive Species

Assessor: Sarah Schumann

Sensitive in 2010

Family

Crassulaceae

Reason for the sensitivity status

There have been several recorded confiscations of this species and others of the Adromischus genus from illegal collection. This genus is in demand and of popular interest in international horticultural trade. Few known locations of occurrence with existing threat causing population decline 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 Vulnerable as it is a range-restricted endemic experiencing ongoing population decline due to habitat loss (Bruyns et al. 2015). This genus is in demand and of popular interest in international horticultural trade, as indicated by several online marketplace, e-commerce and auction sites. There have been several recorded confiscations of this species and others of the Adromischus genus from illegal collection (Confiscation List (2018-2022) provided by Cape Nature, SANBI Kirstenbosch Botanical Garden and SANparks Sendlingsdrift). This suggests that this genus and species 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 has an extent of occurrence of 7167 km², is known from 8 locations where half of these subpopulaitons are experiencing ongoing decline (Bruyns et al. 2015).

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

Few known locations of occurrence with existing threat causing population decline makes this species vulnerable to further population loss. Recruitment and recovery from harvesting may be poor.
