Using birdsong to help make NZ predator-free

One of New Zealand’s leading inventors says new technologies and data crunching should mean the country is predator-free before the Government's set target of 2050.

Grant Ryan, the man who started NZX listed company SLI systems and invented the YikeBike says the goal should be achieved in 2040, 10 years ahead of the target.

Ryan is behind a new project called “Cacophony” which turns birdsong into data and uses sound and light to lure predators into traps.

He thinks the approach has the potential to increase trapping efficiency by up to 80,000 times in the long-term.

The Next Foundation, a philanthropic organisation backed by the Auckland-based Plowman family is investing a significant sum into the Cacophony project.

Next says it will spend $100 million over the next 10 years on conservation projects in New Zealand.
