Othonna intermedia

Assessor: Sarah Schumann

Sensitive in 2010
No
Family
Asteraceae
Reason for the sensitivity status
This genus is in demand and of interest in international horticultural trade, as indicated by several online marketplace. This species may be a potential target as seen on the online platform iNaturalist. Plants of this genus have been targeted and confiscated during criminal prosecutions of illegal plant collecting. As this taxon does not have a vulnerable population size, were exploitation to occur, recruitment and recovery may be possible.
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 Near Threatened as it is known from few locations that are experiencing population decline due to threats of habitat loss to mining, urban, and agricultural expansion (van der Colff et al. 2014). This genus is in demand and of interest in international horticultural trade, as indicated by several online marketplace, e-commerce and auction sites. This species may be a potential target as seen on the online platform iNaturalist. Plants of this genus have been targeted and confiscated during recent criminal prosecutions of illegal plant collecting (Confiscation Lists (2018, 2021) provided by Cape Nature, SANBI Kirstenbosch Botanical Garden, SANBI Karoo Desert Botanic Garden, SANParks Sendelingsdrift Botanic Garden and Department of Forestry, Fisheries and the Environment). This suggests that this genus is being targeted and that this species may be at risk.

Population vulnerability
Population is not vulnerable: size is > 2500 mature individuals, AND the number of known subpopulations is > 5 AND range > 100km2
Justification and references

This taxon has an extent of occurrence of  6914 km² and is known from between 15-20 locations (van der Colff et al. 2014).

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

As this taxon does not have a vulnerable population size, were exploitation to occur, recruitment and recovery may be possible.
