Native Island is a small inshore island - only 80 meters off Stewart Island, southeast of the Ringaringa Passage. Covered in beautiful native bush, not long ago it was home to rats in numbers that were out of control.
The rats posed a serious threat to the island’s native birds (kaka, miromiro, weka, bellbirds and fantails).
In 2011, we teamed up with the Department of Conservation (DOC) to get on top of these pests.
Keeping the rats under control would create a haven for the birds and give the bush a chance to thrive.
DOC committed 120 of our A24 automatic resetting rat traps. We contributed five passionate volunteers who over four days mapped where the traps should go, cut the tracks, installed the traps, and monitored the network’s impact over time.
After 8 weeks, the number of rats almost halved. After 12 months, it was zero.
In partnership with DOC, we helped solved one of the biggest and ongoing challenges for Native Island: reinvasion.
Given the island’s close proximity to the mainland - within swimming distance for a rat - the network of automatic traps acts as a biosecurity tool. Because the traps automatically reset themselves, they’re ready-and-waiting for the next rat to try its luck.
“The Goodnature automatic traps sit in our toolbox because they’re the only non-toxic way for us to knock down and control rats, besides single-action methods which are highly labor intensive. The automatic resetting traps reduce our labor cost by 75%.” – Darren Peters, DOC
Keeping rats under control for over 8 years on Native Island shows that with a well-planned network and minimal maintenance, anything is possible. Whether we’re tackling pests on small islands or large mainlands, we’re proud to play a part in New Zealand becoming predator-free.
