Description
Introduction Wood is one of man's most important resources, and its significance is increasing (Brown and Hillis 1984). Pulp is an important end use of wood, accounting for 522 million [m.sup.3] or 15% of total world wood consumption in 2004 (FAO 2005). In the 1950s, 95% of paper was made from wood fibre, and 90% of that fibre was obtained from coniferous trees. Forty years later--although world paper consumption has increased five-fold--wood fibre still accounts for 90% of total fibre input. Non-coniferous species, however, now contribute 30%, with an increasing fraction of this made up of eucalypts grown mainly in the subtropics and tropics (Brown et al. 1997). Timber from eucalypt plantations has progressively replaced supplies from natural tropical hardwood forests in a variety of solid-wood markets and applications over the past decade (Flynn 2003). The main reasons for this shift are the decreased risk of diverse sources of supply and increased demand for products derived from 'sustainably managed' forests by major international retailing chains (Dunne 2000; Flynn 2003). To meet the increasing global demand for wood, worldwide plantation hardwood timber outputs will need to be increased. This may be done either by increasing the amount of timber obtained from the existing land base, or by planting additional land (Brown and Hillis 1984; Kimmins 1994).
