Eucalyptus grandis Growth Areas and Yield Estimation

Eucalyptus grandis is native to the east coasts of Queensland and New South Wales in Australia, where it goes by the common name of Rose Gum (Meskimen and Francis, 2005). In its native habitat E. grandis, with its pronounced taproot, grows to 55 m in height on the lower slopes in well drained soils. Determination of Climatically Optimum Growth Areas of Eucalyptus grandis have been defined in the ICFR`s Forestry Toolbox (Kunz, 2004), by mean annual precipitation (MAP) and mean annual temperature (MAT). This figure also shows the climatic conditions under which sub-optimum growth would take place because conditions may be too cold (snow/frost), too dry, because occasional drought may occur or because the trees may become diseased. Eucalyptus grandis Yield Estimates Based on Smith`s Rule-Based Approach Using Smith`s (1994) rule-based approach for estimating MAIs of E. grandis, and considering only his climatic criteria and not soil or management factors.
