Using this search facility provides a list of all species present on the checklists available on this web site and their Irish status. The search will include synonyms.
Searching for the status of a species name using the Irish Status option you may restrict the search to a single checklist. In the Irish Status box choose which status you are looking for, that is "Deleted" or "Unconfirmed". Then click the Search button.
Please note that there is no point in searching for those species which are "Accepted", this will return a large number of results.
