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.

皆伐、焚烧与播种（Clearfell, burn and sow，以下简称CBS）是用于低地湿润桉树林木材生产的规定性营林技术。该技术的广泛应用引发了诸多担忧，尤其在采用约90年轮伐期的经营模式时，会导致初期视觉观感不佳、晚演替物种与群落结构减少，以及珍贵用材树种资源衰减等问题。沃拉营林系统试验（Warra silvicultural systems trial）旨在对比CBS与五种替代营林方案，这些方案是通过对全球其他湿润森林应用的营林系统开展调研评估后筛选得出的。上述替代方案包括：保留林下岛的皆伐、焚烧与播种方案、带状/块状皆伐方案、10%分散保留方案、30%聚集保留方案，以及单木/小群择伐方案。详细信息请查阅：http://www.warra.com/index.php/2012-05-15-18-01-11/2012-05-15-18-09-47/item/43-the-warra-silvicultural-systems-trial
