Russell removes traps in areas with no pest detections

What you need to know

• Trap removal is limited to some bush areas where monitoring has found no pests. RNZ describes Russell as approaching pest-free status, not as having achieved it. 1
• The January 2026 update reported no possum catches in Okiato/Te Wahapu for 24 months. In the buffer zone that month, the Trust recorded 91 ship rats, five Norway rats and six possums. The different results show why progress in one area should not be taken as evidence of eradication across the peninsula. 3
• Predator Free Russell builds on more than 20 years of predator control. The Trust says its aim is to eradicate predators while protecting native wildlife, including kiwi and weka. 2
• The Trust’s 2024 annual report describes an expanded eradication footprint of 1,151 hectares. It also estimates that more than 2,000 adult kiwi were present in winter 2024, compared with 756 in 2005. These are Trust-reported figures and do not establish that predator control alone caused the increase. 4
• The available reports describe substantial work and progress in some areas, but do not confirm that all target pests have been eradicated throughout the peninsula. Continued monitoring and control remain part of the effort. 23

Why this matters

The contrast between a sustained period without possum catches in one area and continuing catches in the buffer zone illustrates the challenge of interpreting local monitoring results. The reported kiwi estimates provide important context, but the available evidence does not show that predator control alone produced the population change. 34

What happens next

The Trust’s reporting describes ongoing monitoring and control, including work in the buffer zone. The available sources do not set out when traps will be removed elsewhere or what evidence would be needed for a peninsula-wide pest-free declaration. 123

What we know

• Traps are being removed in some bush areas where monitoring has detected no pests. 1
• The January 2026 update recorded 24 months without possum catches in Okiato/Te Wahapu. 3
• The same update reported 91 ship rats, five Norway rats and six possums caught in the buffer zone during January 2026. 3
• The Trust reports more than 20 years of predator control and an expanded 1,151-hectare eradication footprint. 24

What we don't know

• The reporting does not specify the monitoring duration, detection methods or thresholds used before traps are removed or an area is described as pest-free. 13
• The available sources do not establish which target species and geographic boundaries would be included in a claim of pest-free status for Russell. 12
• The sources do not detail how detection and rapid response to reinvasion will be maintained after traps are removed, or what results will be reported. 23
• The Trust’s kiwi estimates are reported in its annual report; the available material does not establish whether independent monitoring has confirmed them or attribute the increase to predator control alone. 4
