Babiana radiata

Assessor: Juan Swanepoel

Sensitive in 2010
No
Family
Iridaceae
Reason for the sensitivity status
There have been recorded confiscations of species of the Babiana genus from illegal collection. This genus is in demand and of popular interest in international horticultural trade. Few known subpopulations with existing threats causing population decline makes this species vulnerable to 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 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 Critically Endangered (Vlok and Raimondo, 2018). This genus is increasing in demand and of popular interest in international horticultural trade as indicated by several online marketplace, e-commerce and auction sites. There have been recorded confiscations of Babiana spp. from illegal collections (2021, confiscation data provided by Kirstenbosch National Botanical Garden). This suggests that this genus is being targeted and that this species may be at risk from the wild.

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

Two sub-populations of this highly range-restricted species, with an extent of occurence <10 kmĀ² remain after the third population was lost to agricultural expansion in 2006, while remaining populations are vulnerable to road maintenance and construction. The population is considered to have a decreasing trend (Vlok and Raimondo, 2018).

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

The population growth rate is unknown. Population size is severely limited by suitable habitat. Should exploitation occur, even if only cuttings or leaves are collected, compounded with ongoing agricultural and urban expansion and road maintenance having been identified as threats (Vlok and Raimondo, 2018), the chance of populations recovering may be poor.
