Taxonomic Coverage

Species Groups recorded: alga.


Quality control

All the records were validated and verified by members of the Recording Scheme. The majority of records are supported by herbarium specimens. Records may not exist for some species while others may be under-recorded

Method Steps

  1. Records were submitted by a variety of volunteers and professionals, and from the herbarium of Michael Guiry and colleagues at NUI Galway. The validity of submitted records was checked with the help of two panels of referees. Members of one panel were species experts and members of the other had local geographical knowledge and could consider the likelihood of a species being found in a particular place. Doubtful data were not included.
