Disa aurata

Assessor: Sarah Schumann

Sensitive in 2010
No
Family
Orchidaceae
Reason for the sensitivity status
Other species in this genus are known to be threatened by collection of wild individuals. 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 restricted to a specific habitat and is not thought to be threatened (Bytebier & Victor, 2006). Other species in this genus are known to be threatened by collection of wild individuals (von Staden et al. 2012; von Staden & Liltved, 2012).

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 less than 500 km² (Bytebier & Victor, 2006). Further population data is unavailable.

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.
