Weed Management Plan for Andropogon gayanus (Gamba Grass) 9 5.3 Controlling growth and spread (Class B) Land managers and land users in this zone are required to control the growth and prevent the spread of gamba grass. 5.3.1 Small landholdings Gamba grass can be problematic when not actively managed as a pasture. It is therefore recommended that gamba grass be replaced with appropriate alternative plants/pastures on small landholdings where gamba grass is not being used. The following requirements apply to properties of 20 hectares (50 acres) or less in size: 1. inspect the property (including any previously treated areas) to identify any gamba grass infestations. This should be done at least annually prior to flowering and seeding to allow for any necessary control work to be undertaken prior to seeding (refer section 6.1.3); 2. develop and implement a control program to manage/eradicate gamba grass using the control methods detailed in section 6 of this plan; 3. use best endeavours to prevent the spread of gamba grass within or from the property using the control methods detailed in sections 6 and 7 of this plan; 4. design and implement a weed seed spread prevention program which will ensure that no new infestations establish as a result of seed transfer or spread (seed collection and plantings are not permitted) (refer section 7); 5. monitor the results of gamba grass management. In order to evaluate success and get the most out of your program it is recommended that you keep a record of the methods used and management outcomes which is consistent with the example provided at Appendix D; and 6. If your property abuts the A/C zone, and you have gamba grass, you must also implement a buffer zone of at least 40 m width along the B/C and A/C zone boundary. Seed set is to be prevented within the buffer zone (refer section 6.4). 5.3.2 Large landholdings The following requirements apply to properties of more than 20 hectares (50 acres) in size: 1. undertake a property survey early in each calendar year, prior to flowering and seeding times for gamba grass (refer section 6.1.3), to identify any infestations and to allow for any necessary control work to be undertaken prior to seeding; 2. identify and implement a control program to manage gamba grass infestations using the control methods detailed in section 6 of this plan; 3. prevent the spread of gamba grass within and from the property by creating and maintaining buffer zones of a sufficient width (taking into account the level of infestation) to prevent seed spread at locations appropriate to contain gamba grass on or within the property (refer section 6.4); 4. design and implement a weed spread prevention program which will ensure that no new infestations establish as a result of seed transfer or spread (seed collection and plantings are not permitted) (refer section 7);
