Introduction

Pure Salt, a Fiordland based adventure charter boat business, is passionate about conservation and has initiated a project to remove rats from Indian Island/Mamaku in Dusky Sound.

Indian Island/Mamaku Restoration Project

Indian Island was declared pest-free in 2012, however it was reinvaded by rats in 2015/16.

Pure Salt’s goal is reduce the rat population to undetectable levels, in order to protect vulnerable native species on the Island as well as to reduce the risk of rats swimming to nearby rat-free Islands.

The work is being done using a grid network of GoodNature A24 self re-setting traps on an approximate 100 x 100 grid across the island. Over 17 km of track lines need to be cut in order to establish and maintain the 200 traps needed.

The first trip to begin the project work on the island took place on 26-30 October 2018 based on the Pure Salt vessel M.V Flightless. This trip was highly successful and installed 40 GoodNature A24 traps and six rat monitoring lines, so that the team can gather data and track the progress of the project.

The Indian Island/Mamaku Restoration Project is progressing really well with the 200 strong network of A24 traps now on the ground.

The vision is to enable future translocations of native species to Indian Island and to see it play a part in the overall restoration of Tamatea/Dusky Sound. Learnings from this model will be applied to a similar undertaking on the neighbouring, but larger, Long Island.

Pure Salt will begin work on Long Island in October. This will be done in conjunction with Tamatea Adventure which helps by contributing its profits to the Tamatea project.
