Invertebrate monitoring as a tool to measure ecosystem change on sub-Antarctic islands following pest species eradications

Pest species eradications were recently completed on sub-Antarctic Macquarie and Antipodes Islands. Monitoring ecosystem response is important to help quantify the conservation return-on-investment and to inform eradications on other islands, such as those planned for sub-Antarctic Gough and Marion Islands. We tested the use of invertebrates as a tool to measure recovery following pest eradications and examined the utility of different invertebrate groups as indicators of environmental change.
