Managing drought risk in eucalypt seedling establishment: An analysis using experiment and model

Journal Article


Abstract


  • The success of environmental and commercial forestry plantings in Australia's low to medium rainfall zones can be affected by drought-induced mortality during seedling establishment. An analysis of management options for climatic risk like those employed for agricultural industries requires both experimental data and simulation capacity. The growth and survival of two eucalypt species (Eucalyptus melliodora and Eucalyptus populnea) was studied under a range of drought conditions in a field trial near Toowoomba in Queensland, Australia (27��34���S, 151��52���E). The APSIM model was applied to this dataset to investigate the effects of various plant traits on the differing survival rates of each species under the imposed drought conditions. The model adequately described the growth, water use and mortality of both species. A simulation analysis of the long-term survival rates under a range of planting conditions was performed indicating that 90 mm of stored soil moisture was required for managing the risk of establishment losses across a large range of climatic conditions.
