Dataset Details - Seaweeds of Ireland
Marine algae, marine macroalgae, seaweeds currently referred to the phyla Rhodophycophyta, Phaeophycophyta and Chlorophycophyta
To provide phycologists and scientists with a distribution map of algal species and encourage future mapping.
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.
The island of Ireland. The data presented is a sub-set of a larger database of Britain and Ireland held by the British Phycological Society and NUI Galway.
1831 to 2001, when the BPS Mapping Scheme ceased pending publication.
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
The dataset is complete.
The larger British and Irish dataset is held by the Biological Records Centre in the UK and was used in the publication of: Hardy, F.D. & Guiry, M.D (2003) A Check-list and Atlas of the Seaweeds of Britain and Ireland. London: British Phycological Society
