dispersal. Uses The wood has a green density of around with an air-dried density of about . The tree has been logged since the settlement of Western Australia with logging towns appearing throughout the range of the tree and producing hardwood timbers, mostly for construction purposes, for the first 150 years since settlement. The first Karri timber to be felled for export was at the isolated population around Leeuwin, which became known as Karridale. The virtues of the wood were promoted in the 1920s by the state conservator of forests, Charles Lane-Poole, who noted the colonists' preference for other timber as its vulnerability to white ants made it a poor choice for fence posts and railway sleepers. The timber found uses in the state for wagon spokes and wooden pipes, and in England it was found suitable for scantlings by the national railway and telegraph arms by the postal services and was listed among Lloyds shipbuilding timbers as possessing great strength over large lengths. Fire lookouts were established in the forests using the tallest Karri trees, giving the foresters a commanding view of the landscape. The idea of using karri trees in this way was first suggested in 1937 by a young forester, Don Stewart, who later became Conservator of Forests. The first of these was built on a large marri (Corymbia calophylla) at Alco, near Nannup. Eight lookouts were established in the forests between 1937 and 1952. Spotter planes are now used and some of the trees are now used as tourist attractions. Karri wood is a beautiful mahogany colour, lighter in colour than jarrah. It is used extensively in the building industry, particularly in roofs for the length and knot-free quality of the boards. The wood is also used for flooring, furniture, cabinetry and plywood. The heartwood is golden to reddish brown, often with an orange or purple cast, and tends to darken with age. It has an interlocked grain with a uniform medium-coarse texture. It has the reputation of being termite-prone, although it is nowhere near as susceptible to these insects as pine. It is durable against rot. It is also an excellent furniture wood. Karri honey is widely sought after for its light color and delicate flavor. Tourism to this area is also supported by the Karri. Some of the main streets of early Sydney were paved with blocks of Karri but have been long since
