Proof 1080 is saving our species
IntroductionMost of our unique endemic species live in hard to reach places. 1080 is the best tool currently available for large scale predator control in these places.
Monitoring results demonstrate the urgent need for pest control and the effectiveness of aerial 1080.
We do pest control to protect New Zealand’s most vulnerable native species from rats, stoats and possums. We monitor native species carefully to make sure our pest-control efforts are effective.
We use a variety of methods, one of which is applying biodegradable 1080 by air over specified large areas of rugged terrain. Ground-based predator control methods also play an important part, but on their own, these tools have limited use in areas that are difficult to access, too large or too remote.
There are many ways we monitor species before and after pest control. Some of the most compelling results have come from comparison work:
The comparison method
- ‘Area A’ gets 1080 pest control.
- ‘Area B’ doesn’t get any pest control.
- We monitor both areas and compare the results.
Save Our Iconic Kiwi
Kiwi populations around the country are declining at an average of about 2% a year – a serious situation. It’s mostly due to predation upon kiwi chicks by stoats, cats, dogs and ferrets. The goal for Save Our Iconic Kiwi is to turn this decline around, so that every type of kiwi is increasing.
In 2017, we started monitoring southern Fiordland tokoeka (kiwi) at Shy Lake, between Wet Jacket Arm and Breaksea Sound. The goal is to gather data before and after 1080 to ensure that we are controlling pests in large, remote areas of Fiordland in the most effective and efficient way to save the most kiwi.
In the absence of pest control, every chick we monitored was killed by a stoat.
