The Wollemi pine is listed as critically endangered on the IUCN Red List and therefore legally protected in Australia. A Recovery Plan has been prepared outlining strategies for its protection. It was discovered in September 1994 by David Noble a field officer of the Wollemi National Park.

It is known from fossils of the early- to mid-Cretaceous.

Restricted to a small population of about 20 clonal trees in a sheltered gorge surounded by sandstone cliffs in a remote part of the Wollemi National Park just north of Sydney.
