The design of the National Arboretum focuses on the establishment of forests of rare, threatened and symbolic trees from Australia and around the world. 94 of the forests have been planted so far, actively supporting the conservation of global plant diversity.
As a national institution, one of the Arboretum's primary roles is to promote the importance of plant diversity and its preservation, and to incorporate this principle in our communications, education and public awareness programs, in line with the Global Strategy for Plant Conservation (GSPC).
There are 31 threatened species of trees growing at the Arboretum. The National Arboretum collection includes two species that are extinct in the wild, five critically endangered, 10 endangered and 14 vulnerable species. Nine of these threatened species are native to Australia. (correct at the time of publishing).
Threatened trees growing at the National Arboretum Canberra Categories *
Extinct in the wild: The species is known only to survive in cultivation.
Critically endangered: The species is considered to be facing an extremely high risk of extinction in the wild.
Endangered: The species is considered to be facing a very high risk of extinction in the wild.
Vulnerable: The species is therefore considered to be facing a high risk of extinction in the wild.
Near threatened: The species is close to qualifying for, or is likely to qualify for, a threatened category in the near future.
