Pest animal control

Pest animal control regime: Possums and rats are controlled across the site using Timms traps and Pelifeed bait stations. Traps and bait stations are spaced at approximately 150 m intervals. The bait stations are serviced four times a year with pellet baits containing brodifacoum.

Mustelids and hedgehogs are controlled using DOC200 kill-traps and A24 traps at 100 m spacing on lines across the KNE site. More intensive predator control is undertaken behind the banded dotterel habitat on the coastal platform with a line of DOC200 kill-traps and Timms traps spaced 50 m apart. Traps are serviced monthly by volunteers. Between July and February GW provide an additional eight services of the traps across the site to reduce hedgehog numbers and support the banded dotterel breeding. Management plans for the new track network at Baring Head restrict where DOC200 traps can be located.

Mice are controlled in a core area of lizard habitat on the Wainuiomata River escarpment. This is done using block baits containing brodifacoum in wooden tunnel bait stations spaced at 25 m intervals through this area. Additional DOC200 traps were added in the lizard habitat in 2021 to target mustelids and hedgehogs.

Cats are controlled using Timms traps in the lizard habitat on the Wainuiomata River escarpment.

Pest animal control milestones: Timms and DOC200 kill-traps were installed in 2013, with the Pelifeed and wooden tunnel bait stations installed in 2016. The KNE site is part of an OSPRI (formerly TBfree New Zealand) control area for possums.

Surrounding pest control regimes: DOC200 kill-traps are present in the adjacent property to the east. OSPRI’s TBfree programme undertakes intermittent possum control in the area.
