The Warra Silvicultural Systems Trial in Wet Eucalyptus obliqua Forest, Warra Tall Eucalypt SuperSite, From 1997

Clearfell, burn and sow (CBS) is the prescribed silvicultural technique for wood production from lowland wet eucalypt forests. Its widespread adoption raises concerns, particularly due to initial aesthetics, a reduction in late successional species and structures, and a decline in the special species timbers resource when rotations of about 90 years are used. The Warra silvicultural systems trial has been established to compare CBS with five alternative treatments that were selected after a review of silvicultural systems applied in wet forests elsewhere. The alternatives include CBS with understorey islands, stripfell/patchfell, 10% dispersed retention, 30% aggregated retention and single tree/small group selection.
