Toona ciliata

In Australia, the tree's natural habitat is subtropical forests of New South Wales and Queensland, much of which has been extensively cleared. The Australian population was formerly treated as distinct species under the name Toona australis. The species can grow to around 60 m (200 ft) in height and its trunk can reach 3 m (10 ft) in girth. The largest recorded T. ciliata tree in Australia grew near Nulla Nulla Creek, west of Kempsey, New South Wales and was felled in 1883.[7]

The southernmost limit of natural distribution is on basaltic soils, growing west of the Princes Highway near the village of Termeil, south of Ulladulla, southern Illawarra, New South Wales.[8] It also naturally occurs at Norfolk Island.[9]

It is one of Australia's few native deciduous trees. The timber is red in colour, easy to work and very highly valued. It was used extensively for furniture, wood panelling and construction, including shipbuilding, and was referred to as "red gold" by Australian settlers.[10] Heavily and unsustainably exploited in the 19th and early 20th centuries, almost all the large trees have been cut out and the species is essentially commercially extinct.[11] Availability of this timber is now limited.[12]

Timber is currently also harvested in New Guinea.[13] Although it is not generally a viable plantation species, trees are regularly harvested by Forestry in the Atherton region of Queensland. It grows best in an environment with high light levels, however in the relative darkness of the rainforest understorey, it is less susceptible to attack by the cedar tip moth. The cedar tip moth lays its eggs on the tree's leading shoot, allowing the larvae to burrow into the stem. This causes dieback and a multi-branched tree with little commercial value.[14] The tree exudes a chemical that the female cedar tip moth seeks out. This moth does not attack commercial plantings of Asian/African/Australian native meliaceas in South America. As a result, successful planting of Toona ciliata is being observed in many parts of Brazil, including genetic improvement and clonal production.

The red cedar is widely planted in subtropical and tropical parts of the world as a shade tree and for its fast-growing aspect. It is grown in the Hawaiian Islands of the United States, and southern and eastern Africa. In parts of Zimbabwe and South Africa, it has naturalised; growing to maturity and spreading from seed.[15]

Toona ciliata reproduces by seed. It is a prolific seed producer and establishes readily.[5]
