Rats and mustelids tend to move along waterways and linear features including along habitat boundaries, tracks, and fence lines, so placing traps along these features often increases catch rate. Table 3. Summary of control tools and spacing for each target species at Wharekirauponga. * Also targets hedgehogs ** Use bait stations on existing trap lines Target species Control tool Spacing Notes Rat DOC200* Double-set DOC200* DOC250* D-rat Toxin in bait station** • 100 m grid (DOC 200s/Double-set) • 200 m grid (DOC 250) • 50 m intervals on tracks, rivers, ridgelines and perimeter • 100 m grid (D-rat trap offset by 50 m on every DOC trap) • 100 m grid across all available habitat Alternate trap types along lines, use same location as feral cat/possum traps (ensure DOC250 every second trap).
