64 Threat Abatement Plan - Invasion of native plant communities by Chrysanthemoides monilifera 9.3.2 Actions 1.2 and 1.3 Action 1.2 At control category 1 sites, DEC and the DoL will help to develop and implement sitespecific management plans for bitou bush control programs, based on currently available best practice guidelines. DEC will work with councils and private landholders that agree to Action 1.1, to develop site-specific management plans. Action 1.3 Indigenous communities will be encouraged to assist with the development of sitespecific management plans. Site-specific management plans (Action 1.2) Site-specific management plans are required for all control category 1 sites. Each plan will follow the framework established in Chapter 7, and should be completed using the proforma presented in Appendix 9. Consultation with indigenous people/communities (Action 1.3) Indigenous people/communities are encouraged to participate in the implementation of this TAP. In the first instance indigenous people’s/communities’ views will be considered during the development of site-specific management plans, especially relating to cultural values of sites, species, populations and ecological communities, as well as potential impacts that may arise from control. Performance criteria for Actions 1.2 and 1.3 < Site-specific management plans to control bitou bush will be developed for 75% (127 sites) of the control category 1 sites within two years of the publication date of this TAP. < Indigenous people are involved in the development of site-specific management plans. 9.3.3 Action 1.4 Action 1.4 Control of bitou bush is to continue at both the northern and southern containment zones in NSW. The NSW bitou bush strategy outlines the need for the northern and southern containment zones to prevent the spread of bitou bush (see NPWS 2001a). However, the exact location of these containment zones and their management were not identified in the strategy. Work is currently being undertaken at both the northern and southern most distribution of bitou bush in New South Wales, being the Tweed and Moruya/Jervis Bay regions, respectively. Commitment to these containment zones is crucial in limiting future impacts to biodiversity not just in New South Wales. However, what is needed to formalise the process is to: i) define and map the current northern and southern containment zones; ii) outline a strategy with all relevant stakeholders to move each containment zone during the course of this plan; iii) ensure that control undertaken in these areas follows best practice; iv) maintain controlled areas and prevent recruiting plants from seeding; and iv) determine the success of the program by assessing the level of recruitment within the ‘contained’ area.
Threat Abatement Plan - Invasion of native plant communities by Chrysanthemoides monilifera Performance criteria for Action 1.4 < The density of bitou bush at both the northern and southern containment zones is reduced and the zones receded within five years of the publication date of this TAP. 9.4 Objective 2: Monitor the effectiveness of bitou bush control programs Objective 2 Evaluate the effectiveness of control programs at control category 1 sites with respect to the response of priority plant species, populations and ecological communities. 9.4.1 Action 2.1 Action 2.1 DEC will coordinate the monitoring/measurement of bitou bush control programs at control category 1 sites. The primary objective of this TAP is to reduce the impacts of bitou bush on priority plant species, populations and ecological communities. To achieve this objective bitou bush populations will need to be reduced. Although control programs may result in visible or obvious reductions in the density of bitou bush, it is still important to undertake an evaluation of the control program(s) used in terms of their success in achieving biodiversity conservation objectives. Such evaluations must consider: < the effectiveness of the control programs on bitou bush infestations (including reinfestation rates of bitou bush, either from the seed bank or surrounding populations) < the response of the priority plant species, populations or ecological communities to the control of bitou bush < the response of other weed species to the removal and/or the control of bitou bush. Information on the monitoring process is outlined in Chapter 8 and a specific monitoring protocol will be developed in the near future. Performance criteria for Action 2.1 < Establish monitoring objectives. < Establish an experimental protocol to collect data/information. < Establish experiments at as many sites as possible to critically determine the effects of control on bitou bush, priority species and non-target species (including other weed species), using the tier one or tier two monitoring program (discussed in Chapter 8), within 18 months of the publication date of this TAP. < Maintain commitment to undertaking the monitoring programs established over the course of this TAP. < Publish and report on the results as part of the review of the TAP (including incorporation of results into best practice guidelines) to land managers and researchers. Results from both tiers of monitoring to be presented. 65
