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.

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.

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.
