Before removal of invasive species, an estimated 200,000 mice on Antipodes Island were eating their way through between 500 kg and 1000 kg of food per day, depriving native species of crucial resources. How are things looking eighteen months later, following a restoration project?
Recent data from the island shows that 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. Continued sampling next summer will help scientists estimate at what number the populations will stabilize.
With the damaging mice now out of the equation, the unique species of Antipodes Island will no longer have to compete for limited resources, and invertebrates will have total respite from being a mouse’s favorite meal.
With each passing year, you can expect to see the island shift 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 subantarctic. Next stop: Auckland Islands…
