Predator Free NZ: what will it take to achieve our own ‘moonshot’ – Expert Q&A

Posted in Briefings

Nearly six months ago the Government announced it would aim for a Predator Free New Zealand by 2050.

We asked experts about the tools needed to pull off the audacious plan and what the hurdles to success might be.

Q&A with Neil Gemmell

The goals for Predator Free NZ were ambitious but do you think it’s possible for the project to meets its targets by 2050 using current methods and technologies?

“The goal is ambitious but achievable in my view. Current technologies (poisons and trapping) would get us a long way. We have already shown this through eradication efforts of rats on islands.

“However, to do something at a larger scale, relatively quickly, cheaply and with minimal impact on other species, will require the development and adoption of new approaches.”

One of the goals of the project is to do with technological development. What potential advances could help Predator Free NZ meet its targets?

“There are likely four areas of key technological development:

1. Genetic based approaches that target a species’ specific vulnerability, for example, targeted mutations in key developmental and reproductive genes to make a pest species produce offspring that are all male or infertile.

2. New attractants and toxins that are specific to a given species, which will enable us to make poison baits that are attractive to and toxic to a specific animal. It’s likely that these developments will be assisted by new genomic data.

3. Establishment of better ways to detect pest species in our environments using, for example, a network of biosensor devices that would send a digital signal each time they encounter a pest species. This would enable a more targeted approach to eradication.

4. Establishment of a citizen science movement in support of the challenge. This would be integral to the eradication effort via deployment of traps, toxins, etc. within their communities and also engage these citizens in the active monitoring of outcomes, such as tracking the reductions in pest numbers and the increases in other flora and fauna.”

Researchers call for ban on alcohol marketing in sport – In the News

A paper published overnight in the New Zealand Medical Journal has added to the call to ban alcohol marketing and sponsorship from sports. Researchers at the University of Otago surveyed five televised sporting events over the 2014-15 summer and found audiences were exposed to between 1.6 and 3.8 alcohol brands per minute and up to […]
