Eucalypt and Acacia Species for Production of Solid Wood Products in China
The area of eucalypt and acacia plantations in China is currently expanding at a rapid rate and there are now over 1.5 million ha and 200,000 ha respectively of established plantations of these specie. At present the vast majority of these plantations are being managed for the production of pulpwood and the main species are Eucalyptus urophylla and its hybrids, E. grandis, E. globulus, Acacia mangium, A. crassicarpa and some A. auriculiformis. The areas of eucalypt and acacia plantations mat are allowed to grow sufficiently long enough to produce larger diameter trees for sawn timber production are very limited. Those plantations currently available to provide larger diameter material for efficient sawn timber production were generally established prior to the mid-1980s and comprise mainly E. citriodora, E. urophylla x grandis, E. urophylla x camaldulensis, E. urophylla x tereticornis or A. auriculiformis. It is suggested that genetic improvement of some of the current eucalypt and acacia species, along with introduction of other species lesser known in China, should be pursued to support development of forest plantations for sawlog production. Priority species for this include E. camaldulensis, E. pellita, E. torelliana, E. saligna, E. cloeziana, A. cicinnata, A. melanoxylon and A. dealbata. In combination with appropriate silviculutral practice, there is potential for the right varieties of these species to produce high density, fine grain quality sawn timbers suitable for a wide range of applications.
