List of mammals of Heard Island and McDonald Islands


This is a list of the mammal species recorded in Heard Island and McDonald Islands. There are 13 mammal species in Heard Island and McDonald Islands, of which none are thought to be at risk.
The following tags are used to highlight each species' conservation status as assessed by the International Union for Conservation of Nature:
EXExtinctNo reasonable doubt that the last individual has died.
EWExtinct in the wildKnown only to survive in captivity or as a naturalized populations well outside its previous range.
CRCritically endangeredThe species is in imminent risk of extinction in the wild.
ENEndangeredThe species is facing an extremely high risk of extinction in the wild.
VUVulnerableThe species is facing a high risk of extinction in the wild.
NTNear threatenedThe species does not meet any of the criteria that would categorise it as risking extinction but it is likely to do so in the future.
LCLeast concernThere are no current identifiable risks to the species.
DDData deficientThere is inadequate information to make an assessment of the risks to this species.

Some species were assessed using an earlier set of criteria. Species assessed using this system have the following instead of near threatened and least concern categories:
LR/cdLower risk/conservation dependentSpecies which were the focus of conservation programmes and may have moved into a higher risk category if that programme was discontinued.
LR/ntLower risk/near threatenedSpecies which are close to being classified as vulnerable but are not the subject of conservation programmes.
LR/lcLower risk/least concernSpecies for which there are no identifiable risks.
