Euryops longipes var. lasiocarpus | SANBI Sensitive Species

Assessor: Sarah Schumann

Sensitive in 2010

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. Few known locations of occurrence makes this variety vulnerable to population loss. Were exploitation to occur, recruitment and recovery may be poor. Releasing data on this taxon could exacerbate threat and vulnerability.

This species is either similar to 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 Rare as it is known from three subpopulations and is not thought to be threatened (Kamundi & Raimondo, 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. 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 rare species may be at risk to 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 less than 355 km² and is known from three subpopulations (Kamundi & Raimondo, 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 subpopulations makes this taxon vulnerable to population loss, were exploitation to occur.
