Animals in Ireland
14 mammal species are recorded in Ireland in this dataset, none of them currently in a threatened Red List category. Ireland sits in Europe, where 124 species are recorded in total. Every species below is listed because the range description of its IUCN Red List assessment names Ireland.
They belong to 9 families, the best represented being Mustelidae (4), Cervidae (2), Muridae (2). By Red List category: 2 Near Threatened, 12 Least Concern.
These counts come from the text of each assessment rather than from an official country checklist, so a species whose assessment names a region without naming Ireland is missing here, and a wide-ranging animal is counted in every country it crosses. All 14 of them have a full written profile.
