Haemanthus canaliculatus

Assessor: Sarah Schumann

Sensitive in 2010
Yes
Family
Amaryllidaceae
Reason for the sensitivity status
This species is experiencing population decline due to harvesting of wild individuals for horticultural purposes. Several others of the Haemanthus genus were among those targeted and confiscated during criminal prosecutions of illegal plant collecting. This genus is currently in demand and of popular interest in international horticultural trade. Few known locations of occurrence with existing threats makes this species vulnerable to population loss. Recruitment and recovery from harvesting may be poor. Releasing data on this subspecies 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 known from three locations that are experiencing population decline due to harvesting of wild individuals for horticultural purposes as well as habitat loss from coastal development and inappropriate fire regime (Snijman et al. 2007). 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. Several species of this genus were among those targeted and/or confiscated during recent criminal prosecutions of illegal plant collecting (Confiscation Lists (2016-2021) provided by Cape Nature, SANParks Sendelingsdrift Botanic Garden, Karoo Desert Botanic Garden and Kirstenbosch Botanical Garden). This suggests that this genus 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 50 km² and is known from three locations with an estimated population size of less than 1000 mature individuals (Snijman et al. 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

Few known locations of occurrence with a small population that is being exploited and experiencing additional threats (Snijman et al. 2007), places the persistence of this species at risk. Recruitment and recovery may be poor.
