Urban fuelbreak management plan. An integrated pest management approach.
It is suggested that in the management of firebreaks in an urban environment, the use of herbicides for control of bush and tree spp. should form part of an integrated pest management strategy including prescribed burning, mechanical and hand cutting and livestock grazing (goats). To control highly flammable spp. such as Eucalyptus spp., Baccharis consanguinea [B. pilularis] and Cytisus monspessulanus, cultural techniques were only partly effective. An overall spray of 1% glyphosate gave 100% control of B. pilularis and C. monspessulanus, with 2% being required for Eucalyptus spp. resprouts; best results were obtained when the resprouts were >4 ft high. For control of Eucalyptus spp. stumps it was essential to spray within 2 min of felling (with 25-50% glyphosate) to achieve 95-100% control.
