摘要
A single procedure that land managers can readily use to simultaneously monitor populations of multiple pest animal species would enhance capacity to effectively manage environmental impacts in the Australian rangelands. Such a procedure should be efficient and provide a standard for data collection, enabling meaningful evaluation of changes through time. This study compared the efficiency of two indices, namely spotlight counts and a variety of passive activity indices, for detecting rabbit, cat, fox and dingo activity. Spotlight counts were more practical for estimating rabbit activity but were poor indicators of cat, fox or dingo activity. Records of animal tracks on discrete 200 m dirt road segments with favourable substrate and separated by at least 2 km are considered optimal for collectively monitoring relative changes through time in rabbit, cat, fox and dingo activity.
