Australian Conifers of Economic Importance - HOOP PINE
Hoop pine (Araucaria cunninghamii) is the most important
native conifer for wood production in Queensland [4].
It is native to the coastal rain forests from northern New
South Wales to northern Queensland in eastern Australia
and the Arfak Mountains of western New Guinea [3].
Its other common names are Moreton Bay pine or colonial
pine [1].
[3]
This large tree grows to about 60 m, and due to its properties
- knot-free timber of exceptional quality - hoop pine remains
a species much in demand. Early pioneers exploited it as
a resource for this reason (and to clear areas that were
considered to have good potential for farming - both agricultural
and pastoral), so Hoop pine is now grown in large plantations
to ensure sustainable supplies [3].
Most plantations have been concentrated in the south-east
Queensland forestry districts of Brisbane, Gympie, Maryborough,
Murgon and Monto. Approximately 42 000 hectares of rainforest
have been converted to hoop pine plantations in south-east
Queensland [3].
In north Queensland, hoop pine planting was phased out
during the 1970s, although successful plantations still
exist at Gadgarra, Danbulla and Wongabel [3].
Uses: Hoop pine provides an ideal wood for plywood,
cabinet work, furniture joinery, mouldings and linings and
boat building. At one time also used for butter boxes and
fruit boxes. It grows best on deep loams originally carrying
true rainforest, with an average rainfall of more than 800
millimetres per year, and relatively frost-free. It is extremely
sensitive to fire. Harvesting of Hoop pine plantations occurs
at 40 to 55 years [4].
The tree’s name refers to the bark’s tendency to remain
in huge hoops on the forest floor after the timber has decayed
[3].
Both individual trees and small stands of Hoop Pine are
readily found in any of the coastal areas shown on the map,
above, by looking at the horizon for the tallest tree species.
