List of mammals of Heard Island and McDonald Islands explained
This is a list of the mammal species recorded in Heard Island and McDonald Islands. There are approximately 29 mammal species in Heard Island and McDonald Islands.[1] [2]
The following tags are used to highlight each species' conservation status as assessed by the International Union for Conservation of Nature:[3]
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. |
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. |
NT | Near threatened | The 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. |
LC | Least concern | There are no current identifiable risks to the species. |
DD | Data deficient | There is inadequate information to make an assessment of the risks to this species. | |
