Eucalypt wood is light, medium-weight or heavy. The heartwood is light brown to reddish-brown, sometimes dark reddish-brown on exposure, the sapwood is white, cream or light pinkish, 20-60 mm thick and more or less distinctly demarcated from the heartwood. The density of the wood varies greatly between species and also between provenances of a single species (e.g. planted or natural-growing, young or old trees); at 12% moisture content it may be as low as 400 kg/m³ for plantation-grown ''E. deglupta'' (trees of 11-13 years old) to as high as 800 kg/m³ for ''E. deglupta'' trees of natural stands, 980 kg/m³ for ''E. camaldulensis'' and even 1010 kg/m³for ''E. alba.'' The grain is straight to interlocked, texture moderately coarse to coarse. A ribbon figure is often present on quarter-sawn surfaces.
