<strong>the</strong> lower cost, with cost effectiveness depending on <strong>the</strong> price <strong>of</strong> goats at <strong>the</strong> time. Trapping, should only be used during dry times in places where access to water can be controlled. The Judas goat technique is expensive <strong>and</strong> is only appropriate where protection <strong>of</strong> native species <strong>and</strong> ecological communities can only be achieved with extremely low goat densities. 110
Summary <strong>of</strong> <strong>the</strong> effectiveness <strong>of</strong> <strong>feral</strong> goat control methods Method <strong>of</strong> control Efficacy Control method efficiency Target specificity Logistical practicalities Fencing Moderate High Moderate Low High Overall effectiveness 111 Advantages <strong>of</strong> method Disadvantages <strong>of</strong> method Aerial shooting High High High High High Used for control at both high <strong>and</strong> low densities especially in rugged or inaccessible terrain. Effective for eradicating small numbers <strong>of</strong> goats remaining after <strong>the</strong> use <strong>of</strong> o<strong>the</strong>r control methods. Useful for achieving broad scale reductions when goat prices are Ground shooting Low Low High Low Low Can be cost-effective when densities are high. Judas goat High High High Low Moderate Trapping Moderate Moderate Low Moderate Moderate to high Mustering High Moderate Target specific Very effective short-term barriers Expensive, <strong>the</strong>refore impractical for large scale application. Will no permanently stop goats low. Can be a useful adjunct to o<strong>the</strong>r control methods. Effective if local eradication is <strong>the</strong> aim. Most effective during dry times. Cost-efficient when prices for goats are high Moderate Unknown Efficient <strong>and</strong> cost–effective where goats are present in high densities, <strong>the</strong> terrain is relatively flat <strong>and</strong> goat prices are high. Biological control Unknown High Unknown Unknown, but possibly low cost implementation through self dissemination. Requires continuing maintenance Can be expensive at lower goat densities Labour intensive, only suitable for smaller scale operations Difficult in remote areas Requires expensive equipment <strong>and</strong> skilled operators Not applicable at high populations densities. Generally requires road access. Difficult to apply in remote areas. Welfare concerns associated with capture <strong>and</strong> transport <strong>of</strong> goats. Difficult in remote/inaccessible areas Impact on commercial goat industry.
