Relationship of taxonomic error to frequency of observation
Fig 6
Proportion of taxa falling within six uncertainty/frequency classes (UFC).
Approximately 67% of taxa are reliably identified with a high level of certainty (UFC 1–3), and 24.1% (UFC 5) are identified with a low level of certainty. Taxa within UFC 3 and 5 are also considered as rare or having a low frequency of observation.
