Great Island A24 Stoat Eradication Project

Great Island (736 hectares) is in Chalky Inlet, Fiordland and is between 270 and 80 metres offshore. It had a standard uncontrolled population of stoats, monitored at 94% before the operation began. In October 2016, 220 Goodnature A24 traps and 160 monitoring tracking tunnels for stoats were deployed by volunteers and DOC staff.
