Araucaria cunninghamii

[5] Examples of the species can be found on ridges and mountaintops in Queensland's North Burnett region (sometimes in quantity where dry rainforests remain – such as on the summit of Mount Perry and on ridges north of Mount Walsh National Park), inland from Gympie in the Wide Bay, and also at lower elevations around homesteads, where the trees may possibly have been retained for aesthetic value.

The wood is a high-quality timber that is particularly important to the plywood industry and also used for furniture, veneer, joinery, panelling, particle board, flooring and boats.

It is now mainly found on timber plantations; however, the species continues to thrive in protected areas, including Lamington National Park where at least one walking track is named after it.

[8] The plantations in Queensland have been subject to damage by a native rat species, Rattus tunneyi, which digs to the roots of a semi-mature tree and kills it.

[Gressitt 1982 1] Cryptolaemus montrouzieri is a coccinellid predator of mealybug and soft scale insect parasites of A. cunninghamii, and has several characteristics that make it a good biocontrol for use in plantations.
