Disa cephalotes | SANBI Sensitive Species

Assessor: Sarah Schumann

Sensitive in 2010

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 is of Least Concern, 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 of Least Concern (Foden & Potter, 2005). 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

Population data for this species is unavailable but it is regarded Least Concern.

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 is of Least Concern, were exploitation to occur, recruitment and recovery may be possible.
