Before eradication, an estimated 200,000 mice on Antipodes Island were eating their way through between 500 kg and 1000 kg of food a day and depriving native species. Eighteen months later, what changes were detected by the monitoring team and where to from here?
This blog on outcome monitoring describes the various techniques that were used.
The unique flora and fauna of Antipodes Island are flourishing in their new predator-free home, monitoring shows.
Recent data from the island shows pipit, snipe and parakeet populations have rebounded to similar or higher levels than before and immediately after the 2016 operation. The trend suggests further increases are likely. Further sampling next summer will help inform where the populations will stabilise.
With mice now out of the equation, these unique species will no longer have to compete for the island’s limited resources and invertebrates will have some respite from being a mouse’s favourite meal.
With each passing year, we’ll see the island get closer and closer to its pre-mouse invasion state – providing even more inspiration to look towards the next big goal; a predator free New Zealand sub Antarctic. Next stop: Auckland Islands…
