Bait aggregation to reduce cost and toxin use in aerial 1080 baiting of small mammal pests in New Zealand
Abstract BACKGROUND: The metabolic toxin sodium fluoroacetate (‘compound 1080’) is widely used for controlling introduced mammalian pests in New Zealand. For large‐scale operations, 1080 is distributed aerially in bait to kill brushtail possums ( Trichosurus vulpecula Kerr) and ship rats ( Rattus ra...

Here, trials with spatial aggregation of baits in forested habitats were conducted to determine whether this can reduce toxin usage while maintaining operational efficacy. RESULTS: When 1080 baits were aggregated into clusters (by hand sowing) or into strips (by precision aerial deployment), indices of possum relative abundance were reduced by 92–100%, compared with 73–100% reductions using conventional aerial broadcasting, while all methods reduced relative abundance indices of rats by 88% or greater. Radio tracking indicated a kill rate of > 90% against possums, regardless of bait distribution method. CONCLUSIONS: Simply by modifying bait distribution patterns, spatial aggregation can be used to maintain the high encounter rate of pests with 1080 bait that is necessary for operational efficacy, while reducing current toxin usage by up to 80%. Aggregated bait delivery could have relevance for other mammalian pest control scenarios internationally.
