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) 8 5. Management requirements 5.1 Introduction Successful weed management may require significant investment over an extended period of time. In particular, the control of large, established infestations will require careful planning, prioritisation and budgeting. Results may not be immediately apparent: it may require repeated effort to produce obvious reductions in distribution and density. The actions detailed below have been identified as the minimum acceptable requirements needed to achieve the objectives sought and compliance with each declaration class. Landholders may choose to implement a higher level of management than is required by this plan, e.g. a landholder within the B/C zone may chose to eradicate a gamba grass pasture and replace it with an alternative pasture. Similarly it would be reasonable to assume that gamba grass should be eradicated from all urban settings despite major centres falling within the B/C zone. A summary of the management requirements for the A/C zone, the B/C zone and for transport and service corridors are provided at Appendices A to C. The Weed Management Branch (NRETAS), together with the Department of Resources (Pastoral Production) will continue to provide advice pertaining to the use and management of introduced pastoral grasses consistent with the goals of this management plan. The Weed Management Branch will continue to provide training, advice and extension materials to support improved gamba grass management. Please refer to section 9 for a list of resources which will assist in weed management planning and control techniques. 5.2 Eradication (Class A) Land managers and land users in this zone are required to actively identify and eradicate gamba grass infestations and prevent new infestations. To achieve this, the following must be undertaken: 1. inspect the property (including any previously treated areas) to identify and record any gamba grass plants/infestations. This should be done at least annually prior to flowering to allow for any necessary control work to be undertaken prior to seeding (refer section 6.1.3); 2. develop and implement an eradication program for gamba grass infestations using the control methods detailed in section 6 of this plan; 3. regularly monitor/survey land to identify new or re-establishing gamba grass infestations. If your property is on the A/C and B/C zone border, or has previously contained gamba grass, you should undertake regular surveys prior to flowering and seeding times for gamba grass (refer section 6.1.3) to allow for any necessary control work to be undertaken prior to seeding; 4. design and implement a weed seed spread prevention program, which will ensure that no new infestations establish as a result of seed spread (refer section 7); 5. notify the Weed Management Branch of the presence of gamba grass when it is identified in areas in which it has not been found previously; and 6. monitor the results of gamba grass management and keep a record of methods used and management outcomes.
