Research checklists are pre-compiled by biologists.
This is a very controlled method for building a species list, which allows for
specific specimens to be linked to the species names within the checklist and thus serve as vouchers.
Specimen vouchers are proof that the species actually occurs in the given area. If there is any doubt, one
can inspect these specimens for verification or annotate the identification when necessary.
