New Zealand is heavily reliant on agricultural exports so the introduction of an invasive pest or disease could be devastating for the local economy. Pests have already caused havoc with native flora and fauna and many species are now under threat, including the flightless bird, the kiwi. But a new system called PAWS, which stands for print acquisition and wildlife surveillance can monitor pests remotely, and even be used to alert border protection agencies to threats in real time. Simon Morton reports from the outskirts of Christchurch. (Photo caption: Wildlife surveillance monitor for pests in New Zealand 漏 Helen Blackie, Lincoln University/Lincoln Agritech Ltd)
