This Weed Management Plan forms part of a strategic approach to gamba grass (Andropogon gayanus) management in the NT, with the overall aim being to mitigate the damage caused by gamba grass in relation to the natural environment, property and infrastructure and public health. A comprehensive weed risk management assessment found gamba grass to be a very high risk weed where potential exists for successful management.

Weed Management Plan for Andropogon gayanus (Gamba Grass) 27 Appendix C: Summary of management requirements and related actions gamba grass in public transport or service corridors Transport and Service Corridor Objectives Management Requirements Management Actions Eradicate isolated plants and outbreaks. Design and implement a weed control program for gamba grass, including an eradication program for gamba grass infestations within the A/C zone; a control and containment program for gamba grass infestations within the B/C zone. The program should clearly delineate and determine areas of priority. It should also establish the most appropriate control methods. Chemical control (section 6.2); Non-chemical control (section 6.3); and Fire management (section 6.5). Implement early detection and eradication programs. Regularly monitor/survey land, including previously treated areas, to identify new or re-establishing gamba grass infestations at an early stage. Notify the Weed Management Branch of the presence of gamba grass in the Class A management zone if it is identified in an area which it has not been found previously. Eradicate new and outlying populations immediately. Prioritise control in areas with the lowest infestation levels. Regularly monitor/survey land, including previously treated areas, to identify new or re-establishing gamba grass infestations at an early stage. These should be controlled immediately. Outbreaks furthest from major/source infestations should be targeted first. Actively contain large infestation areas. Implement weed control in accordance with the annual control and containment program. Active suppression of seed set may be required outside of high priority areas if road and or construction works pose an immediate spread threat. Prevent/minimise further seed production. Seed production is to be suppressed through: Chemical control (section 6.2); Non-chemical control (section 6.3); and Fire management (section 6.5). To strategically control infestations of gamba grass in transport and service corridors. Design and implement a seed spread prevention program. Design and implement a seed spread prevention program (section 7), to ensure: gamba grass or seed is not moved on machinery or equipment; gamba grass or seed is not moved along transport or service corridors; and seed transport and germination is not facilitated by feral animals and poor land condition. Develop and implement nationally consistent and targeted extension products and activities Information and awareness resources and campaigns are developed and implemented to raise awareness and capacity of landholders to control and contain the spread of gamba grass. Develop and maintain an ongoing monitoring program. A monitoring program should be developed in accordance with the Monitoring Report Template attached at Appendix D. A Monitoring Report should record the type and location of all management actions undertaken, including active control, spread prevention and survey works. The result of these actions should be recorded, even if the desired result was not achieved. Maintain an accurate record of control methods applied and results achieved for possible collation at a Territory level. A monitoring and management record may be requested at any time by the Weed Management Branch. To apply an adaptive approach to weed management. Evaluate the efficiency of control and containment programs over time. Determine the success of various management actions employed and use this information to fine tune the performance of the management program.
