MODULE 8 Control
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
What is control? Control involves reducing the numbers of an IAS to below pre-set levels, or containing its population within a defined area.
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
What Rule Must be Met for Control to be Achieved? Responsible agencies must declare the “support” for projects and long-term commitment
What are the Objectives of Control? Reducing abundance Containing distribution
Monitoring: Answering Questions The process of measuring to detect change
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
Is progress being made towards control objectives?
Are changes occurring with protected resources? This will be your main interest
Any improvements to techniques that might reduce costs, or lead to enhanced outcomes, can be significant. $$
What control methods might I use? There are two main methods of control: Containing distribution Limiting abundance
Limiting Abundance The three main methods are: Mechanical Chemical Biological
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
