Euryops rosulatus

Assessor: Sarah Schumann

Sensitive in 2010
No
Family
Asteraceae
Reason for the sensitivity status
Other species of this genus are known to be threatened by illegal collection of wild individuals. Plants of this genus were among those targeted and confiscated during criminal prosecutions of illegal plant collecting. This genus is in demand and of popular interest in international horticultural trade. A small remaining habitat with existing threat 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 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 (Possibly Extinct) as it has not been collected since 1960 and its 10% remaining habitat is threatened with habitat degradation (Raimondo, 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. Another species of this genus is known to be threatened with harvesting of wild individuals (Raimondo & Turner, 2006).  Plants of this genus were among those targeted and/or confiscated during recent criminal prosecutions of illegal plant collecting. 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

The last remaining habitat of this species was searched in 2007 whereby no plants were found (Raimondo, 2007).

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 high likelihood of this species being extinct means that recovery may not occur, were exploitation to take place (Raimondo, 2007).
