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.

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.

Kākā to be sourced from around the region

Kākā are one of the noisiest and most sociable birds in the forest and Project Janszoon is working on different ways to increase the numbers of these charismatic native parrots in the Abel Tasman.With a beech mast predicted for 2019 we are looking at taking kākā eggs from the wild, hatching them in captivity, and then releasing them into the park.

Aerial predator control results encouraging

Birds and snails in the upland areas of the park are going to enjoy two consecutive years of low rat numbers, thanks to last year’s aerial predator control.Monitoring results show that, in August this year (nearly a year after the October aerial predator control operation), rats above 600m altitude were still tracking at less than 10%. Experts say this is a level below which native bird species will be largely relieved of predation pressure.

Beech planting project expanding

The eroded hills behind Anchorage and on Motuareronui Adele island are not what nature intended.  What we should be seeing is a low forest of kanuka, along with hard and black beech. Instead, fire events over the last 200 years (sometimes planned, sometimes not) have left exposed ridgetops ripe for colonisation by introduced weeds like hakea. Restoration supervisor Helen Lindsay updates us on the beech planting project aiming to bring beech back to the hillsides.

“If you had a Project Janszoon for every national park in New Zealand the whole challenge of biodiversity that we have now would be far, far less.”

Martin Rodd, DOC partnerships director

“Project Janszoon are doing an awesome job in our rohe, we are really supportive and hugely grateful for everything they have done, and are continuing to do.”

John Ward-Holmes, Manawhenua Ki Mohua
