Lagarostrobos franklinii



Lagarostrobos franklinii, common name Huon pine, is a species of conifer native to the wet southwestern corner of Tasmania. Although the common name is Huon pine it is actually a podocarp, not a true pine. It is the sole species in the genus Lagarostrobos. It is a slow-growing, but long-lived tree; some living specimens of this tree are in excess of 2000 years old. It grows to 10 to 20 m tall, exceptionally reaching 30 m, with arching branches and pendulous branchlets. The leaves are spirally arranged, very small and scale-like, 1 to 3 mm long, covering the shoots completely. It is dioecious, with male (pollen) and female (seed) cones on separate plants. The male cones are yellow, 5 to 8 mm long and 1 to 2 mm broad. The mature seed cones are highly modified, berry-like, with 5 to 10 lax, open scales which mature in 6–8 months, with one seed 2 to 2.5 mm long on each scale. Huon pines are some of the oldest living organisms on the Earth.

One particular Huon Pine occurrence which recently received international attention is the small forest patch high on the slopes of Mt Read, near Rosebery, Tasmania. Here, beside the small glacial Lake Johnston, are several hundred trees which share an extraordinary legacy. All are male and all are genetically identical, forming a clone. No variation in DNA has been found between the trees. Even more astounding was the discovery that genetically identical pollen was present in the bottom sediments of Lake Johnston, carbon-dated at 10,500 years. There
are no other Huon Pines within 20 km of Mt Read, and no female trees anywhere in the area.  

Because of the long life of individual trees, tree rings from Huon Pine have been used for dendrochronology to establish a record of climate variation. Our tree was planted in 2021.
