. A new Red List of Irish terrestrial mammals was published in 2009 and all 26 terrestrial species native to Ireland, or naturalised in Ireland before 1500, were assessed. Of these, one was found to be regionally extinct (grey wolf Canis lupus), one achieved a threat status of Vulnerable (black rat Rattus rattus), three were found to be Near Threatened (Leisler's bat Nyctalus leisleri), otter (Lutra lutra) and red squirrel (Sciurus vulgaris)), one was data deficient (Brandt’s bat Myotis brandtii) and the remaining 20 were of least concern.

The following tags are used to highlight each species' conservation status as assessed by the IUCN

:

EX	Extinct	No reasonable doubt that the last individual has died.
EW	Extinct in the wild	Known only to survive in captivity or as a naturalized populations well outside its previous range.
RE	Regionally Extinct	The species is extinct in the wild in the region.
CR	Critically Endangered	The species is in imminent risk of extinction in the wild.
EN	Endangered	The species is facing an extremely high risk of extinction in the wild.
VU	Vulnerable	The species is facing a high risk of extinction in the wild.
