Species: Wollemi pine (Wollemia nobilis)
Status: Critically Endangered (CR)
Interesting Fact: The Wollemi pine is the only surviving member of an ancient group of plants that dates back to the time of the dinosaurs.
More information: An ancient and unusual tree, the Wollemi pine was thought to have been extinct for two million years before it was found growing in a remote gorge in Wollemi National Park, Australia, in 1994. This tall conifer produces both male and female cones on the same plant, with the female cones occurring on the higher branches and producing small, brown, papery seeds which are dispersed by the wind. The Wollemi pine can also reproduce vegetatively, resulting in numerous trunks arising from a single tree. Individuals of this long-lived species may potentially reach 500 to 1,000 years old.
The Wollemi pine has an extremely limited distribution, and fewer than 100 mature individuals now remain in the wild. The species may have been undergoing a slow, natural decline for thousands of years, but it is now under threat from fire, exotic weeds, disease, and any trampling or disturbance by unauthorised visitors. Changing rainfall and temperature patterns associated with climate change may also be a potential threat. Fortunately, this unique conifer is legally protected and a recovery plan is in place to outline management measures. In addition, access to the site where it occurs is restricted. The Wollemi pine is now being grown commercially and the plants distributed worldwide in an effort to protect the wild individuals from collectors and to generate income for this species’ continued conservation.
