Could this just be a text change for the option on 'Exploitation' tab as follows?
Uncertain - No data exists yet showing that this species is exploited in the wild, however it has one or more close relatives (in the same family or genus, 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.
This does not take into account species that are exploited outside of South Africa, such as dwarf vipers.
Action: Allow a family level justification based on current threats.
