Initially, trapping alone controlled rats in the core area to the target level (less than 5% tracking), but after about four years the tracking index increased to 20-30%. Since 2012, rat trapping has been supplemented with a single annual pulse of Pindone cereal pellets in the bait stations. Only small quantities of toxin are required because rat numbers are already substantially reduced by trapping. 300 grams of bait are placed in each internal bait station and 600 grams in perimeter stations. Baits are checked and topped up if necessary 10 days later and all remaining bait is removed after two months. At least half the bait put into bait stations is eventually recovered and carried out of the forest for safe disposal.
Pindone is put out during August – October to coincide with the start of the bird breeding season. Monitoring has confirmed that this is effective.
Bait station for delivering toxin to rats
The Department of Conservation provides the principal effort for control of goats, pigs and dogs. No wild dogs are known to be present. Most dogs that enter the forest are brought in by pig hunters. Control of dogs is therefore via education and permitting for pig hunters, and kiwi aversion training for their dogs.
