Gladiolus symonsii

Assessor: Sarah Schumann

Sensitive in 2010
No
Family
Iridaceae
Reason for the sensitivity status
This genus is in demand and of popular interest in international horticultural trade. Plants of this genus were among those targeted and confiscated during criminal prosecutions of illegal plant collecting. As this taxon does not have a vulnerable population size and it is not thought to be threatened, were exploitation to occur, recruitment and recovery may be possible.
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 six subpopulations that occur within a protected and is not thought to be threatened (Scott-Shaw & Mtshali, 2015). 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 (Victor & Duncan, 2010). 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 over-exploitation.

Targeted demographics
Unknown.
Regeneration potential
This species has a fast population growth rate, and there is a good chance the wild populations will recover from exploitation.
Justification and references

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