A new artificial intelligence-enabled trapping system is being trialled on the Heaphy Track, in a move aimed at reducing pest numbers and improving conservation outcomes on one of New Zealand’s most popular Great Walks.
The Department of Conservation is installing 35 AI-powered traps around key hut sites, including Lewis and Mackay huts, replacing older trap systems.
Smarter pest control
The traps use machine learning to identify pest species such as rats, stoats and possums, triggering only when target animals are detected. DOC says this reduces risk to native wildlife while improving efficiency.
Programme lead Jane Williams says the system will also reduce maintenance requirements.
“These new traps will be much easier to maintain, needing only annual check-ups rather than regular servicing,” Jane says.
Supporting visitor experience
The trial forms part of a wider predator control programme on the track, which DOC says is already delivering results.
“With sustained predator control, people on the track are reporting seeing kiwi in the daytime,” Jane says.
The technology is expected to further support biodiversity recovery, enhancing the natural environment experienced by visitors.
Trial under way
The traps will also be deployed near habitats supporting threatened Powelliphanta snail populations.
DOC says the trial will assess how well the technology performs in West Coast conditions and its potential for wider rollout.
