Table 3, a summary of the National Plantation 75 Inventory (Parsons and Gavran 2005), indicates that Australia has only 359 ha of 76 mixed-species plantations, of which 305 ha (85%) is privately owned, and planted 77 since 1995.... In PAGE 4: ... The Australian Tax Office currently has 93 such Rulings 100 relating to timber plantation (Table 5); of these, all but three relate to monocultures 101 (or in the case of sandalwood, a host plant plus the intended crop). The three 102 polyculture Rulings involve two species planted in alternate rows by BioEnergy 103 Australia ( Table2 ). Table 4 overstates the real position of mixed plantings, because it 104 does not take areas into consideration, and Rulings relating to monocultures tend to 105 refer to larger areas than those relating to mixed plantings....

The simplest mixed-species 265 planting in which two species alternate by rows (as is proposed by BioEnergy 266 Australia, Table2 ), should involve no additional cost apart from some operations 267 planning.

For instance, EcoForest Limited (mentioned in Table2 ) was set 284 up in 1997 to establish mixed-species plantations in the Hunter Valley region of New 285 South Wales (NSW).

Five paired sites, containing sugarcane plantation and Eucalyptus saligna plantations established on, and adjacent to, abandoned cane fields, were sampled ( Table6 ). Using this approach, they were able to show that the net effect of afforestation on total soil carbon after cultivation depends not only on the new carbon gained, but also on the carbon lost from previous management.... ..."
