1. MODULE 8 Control

2. Module Objectives Know what control is and how it differs from eradication Recognise the requirements that must be met if control objectives are to be achieved and desired outcomes sustained Recognise the 3 main approaches to control

3. What is control? Control involves reducing the numbers of an IAS to below pre-set levels, or containing its population within a defined area.

4. How does control differ from eradication? Control: –Individuals are still present, but at lower densities Eradication: –Eradication involves the complete removal of a targeted IAS population

5. What Rule Must be Met for Control to be Achieved? Responsible agencies must declare the “support” for projects and long-term commitment

6. What are the Objectives of Control? Reducing abundance Containing distribution

7. Monitoring: Answering Questions The process of measuring to detect change

8. What do I need to know to control IAS Effective methods The target species The site Measuring your control effort will also provide essential information

9. Is progress being made towards control objectives?

10. Are changes occurring with protected resources? This will be your main interest

11. Any improvements to techniques that might reduce costs, or lead to enhanced outcomes, can be significant. $$

12. What control methods might I use? There are two main methods of control: Containing distribution Limiting abundance

14. Containing Distribution

15. Limiting Abundance The three main methods are: Mechanical Chemical Biological

16. Mechanical control

17. Chemical Control

18. Biological Control

19. Successful control requires sustained commitment and support Control involves limiting abundance and/or containing distribution Integrated pest management approaches are being Increasingly employed Setting appropriate goals and realistic control objectives, and monitoring results and outcomes as control regimes proceed are critical Summary
