Some of the economic research being undertaken in woody weed management in Queensland's rangelands is presented. The focus of the research is to link economic and ecological models of grazed lands which contain exotic woody weeds in order to assess their impacts. The constraints imposed by economic considerations on control options for woody weeds are assessed by considering two examples. The first involves linking a benefit cost analysis of control to a model of spread of prickly acacia. The second is an assessment of rubber vine containment using fire management. Preliminary results of both examples are presented and economic implications discussed.
