Project 2.3

Leader: Dr James Russell, University of Auckland

Mission Statement

By providing end-users with the tools (and deployment strategies) needed to eliminate small mammal pests across natural and production system through a national partnership that ensures all hurdles to application are recognised and addressed.

Summary

The ability to cost-effectively keep rats, stoats and possums at zero density will be transformational for New Zealand conservation.

The ultimate outcome is to enable scaling-up of current efforts to landscape-scale pest freedom. This project will accelerate the provision of improved tools, methodologies and strategies for mammal pest control in general and for local elimination in particular. They will be socially acceptable, cost-effective and targeted next-generation technologies that have been proven at pilot scale to effectively eliminate small mammal pests.

A step change in research innovation will be achieved by identifying and making the advances necessary to achieve end-users’ and stakeholders’ desired outcomes from within the fields of ‘lures/repellents’, ‘surveillance/detection/monitoring’, ‘improved toxins and devices’, ‘genetic-based tools’ and ‘landscape-scale strategy (the top five themes identified for progress in the 2012 Pest Summit).

Widespread suppression and eradication of small mammal pests (possums, rodents, mustelids):

  1. Novel tools and technologies for cost-effective, landscape-scale control, eradication and surveillance of small mammal pests (e.g. strategy and tools for remote wireless trapping/surveillance systems),
  2. Designer lures to increase knockdown efficiency,
  3. Tailoring specific lethal control agents (and advanced delivery systems) for priority small mammal /invertebrate pests and pathogens (e.g. via genome mining or molecular approaches for designer toxin receptor targets).
  1. What are the current, emerging and on-the-horizon technologies nationally and internationally?
  2. What are the end-user needs and pathways for novel technologies?
  3. What are the new ‘product specifications’ needed to achieve stakeholder and end-user goals?
  4. Are there social hurdles and how can they be overcome?
  5. Can we identify synergies between current and developing technologies?

This project will be led by Dr James Russell, supported by a new collaborative research leadership team including a wide range of skills, including design, engineering, social science and VM, in addition to the conventionally applied disciplines of wildlife management and pest control.

Predator Free 2050

Predator Free 2050 is an ambitious goal to rid New Zealand of the most damaging introduced predators that threaten our nation’s natural taonga, our economy and primary sector.

Vertebrate pests

Research focusing on protecting native ecosystems and primary industry through improved understanding of pest responses to management, and the role of pests as disease carriers (bovine tuberculosis and avian malaria). This understanding is then used to provide new and improved management strategies, tools and techniques - ranging from biological control to traps and toxins.

A conservation summit on Predator Free NZ 2050

From Our Changing World, 9:20 pm on 4 August 2016

The New Zealand Government has thrown its support behind a radical idea: saving our native biodiversity by declaring war on predators. So are we looking at a future where hihi and tuatara can safely roam the mainland forest once more? Andrea Byrom, from Manaaki Whenua, is Director of the Biological   Heritage National Science Challenge. James Russell is a biologist from the University of Auckland. Peter McClelland is an eradication expert, who led the rat eradication on subantarctic Campbell Island. They talk about the importance of ‘social license’ and getting community support, and share their thoughts on what will be needed to make New Zealand predator-free.
