Huon
pine can reproduce both vegetatively ie from fallen
individuals, and by seed. Although extremely slow growing,
the trees can attain heights of over 40 m, and reach ages in
excess of 2,000 years, making it among the longest-lived
organism on earth. International headlines were made with
the discovery of a stand of Huon pines on Mount Read, that
were quoted as being in excess of 10,000 years of age. It
was found that all the individuals in this population are
genetically identical, and are all males. The stand arose
from one or a small number of individuals, and has
maintained itself by vegetative reproduction. In actual
fact, no individual tree in the Mount Read stand is 10,000
years old, rather, the stand itself has been in existence
for that long. Source:

Facts About Huon
Huon pine only grows in the cool, wet
areas of southern and western Tasmania. It prefers to have
‘its feet in water’ so you will usually se it clinging to
a rivers edge. Occasionally it grows in swampy areas, away
from rivers and lakes, like those at Teepookana.
Other common names for the Huon Pine include: White
Pine, Macquarie Pine, this is confusing as it is a podocarp (Podocarpaceae), and
not a pine (Pinaceae).
Pollen records indicate that Huon pine
was growing 135 million years ago, when the great
super-continent known as ‘Gondwana’ existed. Although only
found growing in Tasmania, it is related to species in
Chile, Malaysia and New Zealand.
A 380 year old Huon pine, grows on
average 1 mm per year.
Huon pine is Australia’s longest lived
species. Trees older than 2,000 years have been found
growing on Tasmania’s west coast. It is extremely slow
growing. If you look at a cross section of the trunk, you
can see how close the growth rings are.
The Huon pine is extremely durable and
resists rot due to the presence of an essential oil called
‘methyl eugenol’. This is why it was, and still is, in
such demand for boat building. Once cut, logs can remain
intact, even in water, for thousands of years. Radio
carbon dating indicates that two logs found recently in a
west coast river were alive over 7,000 years ago.
