Nelson Halo - a community predator trapping initiative
The Nelson Halo is a community‑driven predator control and habitat enhancement initiative led by Nelson Nature. It surrounds the predator‑free Brook Waimārama Sanctuary, extending predator control and restoration work into the wider landscape to create a safe haven for native wildlife.
The goal is to bring the wild back into people’s lives, enabling native birds, lizards, bats, insects, and other species to move freely beyond the Sanctuary fence into surrounding neighbourhoods, reserves, and catchments.
Why the Halo?
The Brook Waimārama Sanctuary is predator‑free — but predators remain immediately outside the fence.
Without landscape‑scale control, native species leaving the Sanctuary encounter:
- rats
- stoats
- weasels
- possums
- feral cats
The Halo expands the Sanctuary’s protective buffer, helping:
- native bird populations recover
- lizards and invertebrates survive
- urban biodiversity flourish
- the wider ecosystem become more resilient
The Halo model is used to connect people, community groups, and backyard trappers into a shared biodiversity movement.
Nelson Halo Map
The Brook Waimārama Sanctuary
The Brook Waimārama Sanctuary is a 691‑hectare, pest‑free fenced sanctuary located in the Brook Valley, just a few kilometres from Nelson City Centre. It provides a safe haven for native wildlife and forms the core of long‑term wildlife restoration efforts in the Nelson region.
The Nelson Halo builds on the success of the Sanctuary by creating a pest‑reduced wildlife corridor linking the Sanctuary with the city and surrounding hinterland. The aim is to increase the number of native birds and other wildlife by providing abundant food and safer habitat beyond the Sanctuary fence. As populations grow within the Sanctuary, birds and other species naturally spread into surrounding areas, where the Halo supports safe feeding and breeding.
The core Nelson Halo extends from the city backdrop toward Richmond, covering Council reserves from Marsden Valley in the south to Sir Stanley Whitehead Park in the north, along with the parks, rivers, streams, gardens, and private land in between.
The wider Halo reaches through Atawhai and Nelson North, into the Maitai and Roding water catchments, and out to the coast.
The success of the Halo relies on collective effort and collaboration. It is supported by community trapping and restoration groups, iwi, the Department of Conservation, private landowners and residents, researchers, and Nelson City Council, all working together to restore and protect Nelson’s native wildlife.

Take up backyard Trapping
If you haven’t already, be sure to grab yourself a predator trap for your backyard. Backyard trapping is one of the most effective ways our community can help restore the mauri of our environment.
If you’re already trapping at home, encourage your neighbours — the more people trapping, the safer our environment becomes for native birds and invertebrates.
For more information on which traps to use visit our 'Animal Predator Control' page.
Or contact Nelson Nature at nelson.nature@ncc.govt.nz or visit trap.nz to find a community trapping group in your area.
What You Can Do
- Trap your backyard for rats, stoats, and possums
- Join a local trapping or restoration group
- Remove invasive weeds (old man’s beard, banana passionfruit, climbing asparagus)
- Keep cats inside at night
- Keep dogs on leads where wildlife (weka, shorebirds) are present
- Report wildlife sightings on iNaturalist
- Participate in the NZ Garden Bird Survey
- Plant native trees to provide bird feeding habitat
- Build a wētā hotel or lizard shelter with rocks and dense shrubs
Every backyard and every trap strengthens the Halo.
