Download Comparative detection probabilities, surveillance sensitivity and costs of four survey methods for managing invasive Bennett’s wallaby in South Island, New Zealand

Knowing the detection probabilities of surveillance tools will help inform how much surveillance effort is required to confidently determine if wallabies are absent in an area and/or to prove elimination has been achieved. This research compares the detection probabilities, surveillance sensitivities and cost of surveillance between helicopter surveys with observers; a ground hunter with detector dogs; camera traps and helicopter surveys using a thermal imaging camera.
