Lachenalia viridiflora

Assessor: Sarah Schumann

Sensitive in 2010
Yes
Family
Hyacinthaceae
Reason for the sensitivity status
This genus is in demand and of popular interest in international horticultural trade. Several species of the Lachenalia genus were among those targeted and confiscated during criminal prosecutions of illegal plant collecting. Few known locations of occurrence with existing threats causing population decline makes this species vulnerable to further population loss. Were exploitation to also occur, 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 Endangered as it is highly range restricted, known from three to five remaining locations and is threatened by habitat loss and degradation (Duncan et al. 2015). 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. This species is known to be utilized and collected from the wild for horticultural trade. Several species of this genus were among those targeted and/or confiscated during recent criminal prosecutions of illegal plant collecting (Confiscation lists (2020-2021) provided by SANBI Karoo Desert Botanical Garden and Kirstenbosch Botanical Garden). This suggests that this genus may be targeted and that endangered species may be at risk to over-exploitation.

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 13 km² and is known from three to five remaining locations (Duncan 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

Range restriction, few known locations and several threats (Duncan et al. 2015), makes this species vulnerable to further population loss. With this risk of over-exploitation, recruitment and recovery may be poor.
