Plan to Protect Environmental Assets from Lantana 4.8.3 Action 6.3 Action 6.3 Key stakeholders will foster research into the effects of lantana control on native fauna. There have been few studies on how removing a weed from an ecosystem affects fauna (see review in Gosper 2004), especially when the weed has become dominant and may have been so for many years or decades. The disturbance involved in removing weeds may affect many fauna species long after the actual control event has taken place (for example, from increased light, soil disturbance, trampling of the ground, removal of a food source and/or the direct effects of management techniques like fire). Also, some native plant species that these animals use for habitat may take many years to recover following control (for example see Turner and Virtue 2006). Performance indicator for Action 6.3 Support the establishment of sites where studies can be undertaken to determine the effects of lantana control on fauna. Develop research projects on the effects of lantana control on fauna. 4.8.4 Action 6.4 Action 6.4 Key stakeholders will foster research into the effects of herbicide s on priority assets. Herbicides have been used successfully to control lantana in Australia for many years. However, there is little data available about the impact of herbicides on native flora and fauna. This needs to be investigatedso that high-priority assets are not threatened by the application of herbicides. Performance indicators for Action 7.2 Establish experiments to determine the non-target effects of herbicides used in lantana control. Collect data where possible during monitoring programs. 4.9 Objective 7: Review data and set future priorities Objective 7 Establish guidelines for future control programs and research projects based on the outcomes of this Plan. 4.9.1 Actions 7.1 and 7.2 Action 7.1 Key stakeholders will examine new data and integrate it into future control/management strategies. Action 7.2 National Lantana Management Group and other stakeholders will examine new data and establish future priorities forlantana management . After five years of implementation, the outcomes of this Plan should be used to determine future management and research objectives to reduce lantana’s impact on native biodiversity. 29
Plan to Protect Environmental Assets from Lantana Performance indicator for Action 7.1 Re-evaluated management plans and control strategies based on data collected in Actions 3.1 (monitoring of control programs), 6 .1 (decline of native plants), 6.2 (fauna and lantana), 6.3 (fauna and control) and 6.4 (herbicide impacts), as well as any other data available, during the final year of this Plan. Performance indicator for Action 7.2 Determine future priorities for lantana management and research objectives based on data collected from the above. 30
