Documentations Received Since 2000

Documentations are the starting point of Records Committee reviews which is the evaluation of an occurrence of a rare or out-of-season species. Documentation numbers will always be higher than reviews because some reviews are supported by multiple documentations and some are reviewed in a subsequent year. Occasionally a documentation is submitted for a species that does not need a review. We appreciate everyone's effort to add to our knowledge.
