Haworthia floribunda

Assessor: Sarah Schumann

Sensitive in 2010
No
Family
Asphodelaceae
Reason for the sensitivity status
This species is experiencing population decline due to collecting for the specialist succulent horticultural trade. This genus is in demand and of interest in international horticultural trade. There have been several recorded confiscations of species of the Haworthia genus from illegal collection. A declining population size due to several existing threats makes this species vulnerable to further population loss. Recruitment and recovery 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 experiencing ongoing population decline due to habitat loss, degradation and collecting for the specialist succulent horticultural trade (Vlok et al. 2020). This genus is in demand and of interest in international horticultural trade, as indicated by several online marketplace, e-commerce and auction sites. Recently several species of the Haworthia genus have been illegal harvested. Plants of this genus were among those targeted and/or confiscated during a recent criminal prosecution of illegal plant collecting. There have been several recorded confiscations of species of the Haworthia genus from illegal collection (Confiscation List (2018-2021) provided by Cape Nature and SANBI 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 has less than 20 small subpopulations with an estimated population size of less than 10 000 mature individuals however this modest population continues to decline which could result in its vulnerability (Vlok et al. 2020).

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 removed from the wild.

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 declining population size due to several existing threats makes this species vulnerable to further population loss. Recruitment and recovery may be poor.
