Ledebouria galpinii

Assessor: Sarah Schumann

Sensitive in 2010
No
Family
Hyacinthaceae
Reason for the sensitivity status
This genus is in demand and of popular interest in international horticultural trade and medicinal trade. Several species of this genus were among those targeted and confiscated during criminal prosecutions of illegal plant collecting. A small population size with existing threats makes this taxon vulnerable to further population loss. Were exploitation to occur, recruitment and recovery may be poor. Releasing data on this species could exacerbate threat and vulnerability.
This species is either similar to another sensitive species or belongs to a group containing sensitive species, and is extremely rare in the wild. The localities of wild populations need to be protected to avoid loss to exploitation, which, due to its rarity, could drive the species to extinction within a very short time.
Exploitation extent
Uncertain - No data exists yet showing that this species is exploited in the wild, however it has one or more relatives or look-alike species (found in South Africa or globally) that are known to be utilised. This species has a similar life form or other relevant traits to its exploited relative(s), making it highly likely that it would be exploited for the same purposes.
Justification and references

According to the SANBI Red List Assessment, this species is Endangered as it is known from three locations that are threatened with ongoing habitat loss from afforestation and development, degradation from inappropriate fire regime, trampling and alien plant invasion (Hankey et al. 2008). 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. Other species in this genus are known to be threatened by illegal plant collection as well as being popular in ethnomedicinal plant trade (Lötter & von Staden, 2016; Crouch et al. 2007). Several species of this genus were among those targeted and/or confiscated during recent criminal prosecutions of illegal plant collecting (Confiscation lists (2019-2021) 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 15 km² and is known from three locations (Hankey et al. 2008).

Targeted demographics
Unknown.
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 and several existing, ongoing threats (Hankey et al. 2008), places the persistence of this species at risk. Were exploitation also to occur, recruitment and recovery may be poor.
