Predator Control Programme

In partnership with Auckland Council, and with funding from five local boards; Albert-Eden, Puketāpapa, Maungakiekie-Tāmaki, Waitematā, Ōrakei, Conservation Volunteers NZ (CVNZ) currently operates a predator control programme in over 30 parks throughout Auckland. 

Introduced predators such as possums, rats, mustelids, and mice impact all levels of the ecosystem by browsing on native vegetation, preventing forest regeneration, and predating on native wildlife thus pushing many species to the brink of extinction. Our predator control programme aims to eradicate introduced predators from our urban parks, allowing our native flora and fauna to flourish.  

Each year CVNZ and the Auckland Council host two, 3-hour training sessions, in which we equip volunteers with all the hands-on experience and knowledge they will need to successfully monitor and maintain a trapline. Volunteers are only required to attend one training session and once trained, are assigned to one of the many parks where we currently operate a predator control network. Here, volunteers are responsible for baiting and resetting traps, and recording their catches using a data management software called CatchIT. Previous experience using CatchIT is not required as this is taught as part of our training sessions. Monitoring a trapline can take anywhere between 30 and 90 minutes, depending on the number of traps and the location and terrain of the trapline. Volunteers have the freedom to choose when they monitor their trapline, although most volunteers tend to check their traps fortnightly or monthly. Before assigning volunteers to a trapline, we ask that volunteers can commit to a minimum of 12 months and ensure that they are comfortable working alone in forested areas and handling rodent and possum carcasses. Spaces on our training sessions are often limited, so priority is generally given to those who either live or work locally to one of our pest control areas.  

The Auckland Council and CVNZ supply all the tools, equipment and knowledge needed to maintain traplines safely and successfully.  

Our predator control programme wouldn’t be possible without the help of our dedicated volunteers.
