101 Certainty of species determination
Information about the certainty of the species determination should be given.
The subspecies and/or the variant should be specified use the field “Other observations”.
Apart from aspects of quality assurance, this enables to transfer national additional information like subspecies, variant or cf. (species determination is uncertain).
Also for questions of species richness it is important to know if species which could be only determined on genus level (Genus sp.) are certainly different from those which are already part of the species list of the respective survey.
In practice, the majority of species records are assigned to Certainty code “5”.
