Secondary salinity involving high, saline water-tables affects large areas of agricultural land
in south-eastern and western Australia. Tree planting is one approach for lowering the saline
water tables. Such plantations, especially of Tasmanian blue gum (Eucalyptus globulus ssp.
globulus), could become a significant fibre source for the pulp and paper industry.
This report addresses whether growth of Eucalyptus globulus ssp. globulus in salt-affected
environments influences key fibre properties important in paper production.
Research was conducted on plantations near Shepparton, Victoria, irrigated with pumped
saline ground water of 5-10 dS m-1, and with pot trials at the School of Forestry, Creswick,
Victoria. The combined results indicate that levels of soil salt that do not significantly affect
tree growth also have no measurable effect on fibre properties, at least in the first 4 years after
