Our story

Project Janszoon is a philanthropic trust on a mission to restore and preserve the Abel Tasman’s rich wildlife for all to enjoy.  It is a team effort involving conservationists, iwi, locals, scientists and tourism operators. Together we’re making a difference.

Eyes on THE Abel Tasman

our work

We’re working with the Abel Tasman Birdsong Trust, the Department of Conservation, iwi -Ngāti Tama, Ngāti Rārua and Te Ātiawa – and the community to restore the park’s rich wildlife. Together we’re getting rid of pests and weeds, bringing back native wildlife and bush, and inspiring a culture of care for the Abel Tasman.

Predator Control

Introduced predators kill 68,000 native birds in New Zealand every day.
In the Abel Tasman, we want to give native birds and plants a chance to thrive.

Restoring Wildlife

We’re bringing the birdsong back to the Abel Tasman. Since 2014, kākāriki, kākā, tieke/saddleback, whio and pāteke have all been released into the park.

The Fire Smart programme was set up to reduce the fire risk in the park by getting rid of gorse and replacing it with less flammable natives.

Weed Control

There are 113 different weed species in the park – many spread from bach owners’ gardens. The worst of these weeds are known as the ‘Filthy 14’.

Wasp Control

Wasps are a pain for visitors and bad for biodiversity. They compete with bats, birds, insects and lizards for food and eat huge numbers of native insects.

Wilding Pines

Pine trees can dominate the ecosystem and compete with native plants for moisture, nutrients and sunlight. We’re supporting efforts to eradicate pesky pines from the park.

Project Janszoon has a wonderful team of volunteers who do everything from dune restoration and tree planting to possum trapping and kākā monitoring. Volunteering is a great way to give back and see a different side to the Abel Tasman. We’re always keen for an extra pair of hands. If you live locally and are keen to be involved get in touch.

Hares and Hoar Frost – restoring Hadfield Clearing

The 793ha Hadfield Clearing was the last piece of land to be bought into the Abel Tasman National Park, when it was purchased in 2003/4. Restoration efforts were focused on a 25ha paddock which was then covered in rank grass with gorse moving in and the remnants of farm buildings and old fences still standing. Restoration work involved battling against browsing hares and frosty winters to get plants to a point where they could survive.
