Boffa Miskell Ltd | Pest Animal Management Plan | Wharekirauponga Compensation Package | 30 May 2022 25 wooden chimney boxes to help exclude non-target species. Equal numbers of each type are recommended to increase trap diversity. 7.3 Trap locations Trap locations are shown in Maps 5-7 and their spacings are summarised in Table 3. This trap network is designed to complement and work alongside the bait station network, and as such spacings are designed for suppression alongside the use of toxins. Rat/mustelid/hedgehog traps (e.g. DOC series traps) will be deployed on a 100 m grid across the entire control area and at 100 m intervals along tracks, rivers, ridges, and the perimeter. Some standard DOC200 traps will also be swapped out with Double-set DOC200 traps to better target stoats. DOC250 (also capable of killing ferrets) traps will be every second trap on a 200 m grid and all other trap lines. For rat and mice control, D-rat traps will be set every 100 m on the DOC trap grid and this will be offset by 50 m from every DOC trap (D-rat traps will be in between DOC traps). D-rat traps can be set to the mouse sensitivity setting placed alternating in tunnels and on trees (to target both mice and rats). Additionally, standard ‘snap-trap’ mouse traps will also be placed inside all DOC trap boxes, as per Fig. 1 to reduce bait interference and to assist with ongoing mouse control. Fig. 1. Example of mouse trap placement inside DOC trap. Possum/cat-capable traps (SA2 Kat traps and Timms traps) will also be deployed along the same lines and locations as rat/mustelid/hedgehog traps (to allow for ease of servicing and reduce trampling disturbance), the traps will however be placed at 200 m intervals along rivers and ridges and 100 m on tracks and the perimeter, these traps will not follow grid spacing. The control devices required are summarised in Table 3. Note bait stations targeting rats and possums (e.g. Philproof Mini Gen II) will also be deployed, as shown in Map 4. Bait stations will be spaced on a 100 m grid at existing trap locations across the control area where possible. Each trap location will need to be micro-sited upon deployment (i.e. refined on a fine scale within several meters in the field, based on the broad-scale locations in Maps 5-7). This ensures each trap is placed within suitable micro-habitat for the target species to maximise capture success. The target mammalian predators do not move through the landscape uniformly but
