Introduced rodents have been eradicated from large numbers of offshore islands using toxic baits; however, toxic baits have been linked with negative impacts on non-target species. The present study assessed the bait take of target (house mouse, Mus musculus) and non-target (buff banded rail, Rallus philippensis) animals on Northwest and Heron Islands in the Great Barrier Reef. Three non-toxic bait formulations (wax block, pellet and grain) were tested and each was applied at 1 kg ha(-1) in six treatment grids. The tracks of animals visiting the baits were identified using 30 tracking stations per treatment grid. A tracking station consisted of a track-board placed in the centre of a sand-pad. Mean bait take differed significantly between the formulations: birds took more grain bait than wax block bait; mice took more wax block than grain bait. Both mice and birds were equally selective of pellet bait. Thus, the findings indicate that wax blocks are the most suitable formulation for future baiting programs to eradicate mice on these and other islands.
人们已使用有毒诱饵在大量近海岛屿上消灭了外来啮齿动物；然而，有毒诱饵已被证明会对非目标物种产生负面影响。本研究评估了大堡礁西北岛和鹭岛对目标动物（家鼠，小家鼠）和非目标动物（斑胸田鸡，菲律宾秧鸡）的诱饵摄取情况。测试了三种无毒诱饵配方（蜡块、颗粒和谷物），每种配方均以1千克/公顷的用量施用于六个处理网格中。使用每个处理网格中的30个追踪站来识别访问诱饵的动物足迹。一个追踪站由放置在沙垫中心的足迹板组成。不同配方之间的平均诱饵摄取量存在显著差异：鸟类摄取的谷物诱饵比蜡块诱饵多；小鼠摄取的蜡块诱饵比谷物诱饵多。小鼠和鸟类对颗粒诱饵的选择性相同。因此，研究结果表明，蜡块是未来在这些岛屿和其他岛屿上消灭小鼠的诱饵计划中最合适的配方。
