Araucaria cunninghamii is a species of "Araucaria" known as hoop pine. It has cedar and hoop pine joinery throughout. Floors throughout are 6in wide hoop pine. Mount Superbus was originally covered in dense hoop pine forests. It features eucalyptus forests, small sections of rainforest, and plantations of Hoop Pine. The establishment of hoop pine plantations in the region began in 1938. Amidst these structures stand three mature bunya and hoop pine trees. The Morganville extension generated some year round traffic in hoop pine logs and cattle. With the exception of hoop pine, native timbers did not do well in plantations. Many survive to the 21st century, including fine examples of Hoop Pine and Bunya Pine. The state government established a hoop pine nursery at Jimna in 1935. Hoop pine was very successfully collected from the area. A common associate tree is the Hoop Pine. There are extensive old Jacaranda, Poinciana, Hoop Pine and Mango trees throughout the area. Such outbreaks were serious as hoop pine is particularly vulnerable to fire.
