Keeping your kauri safe

 

 

Do you have kauri on your land? or part of your view?

We've spoken to a number of Kaipatiki people for whom the kauri on their land, or just over their fence, are very important - a source of pride and pleasure.

They are horrified at the thought of losing it and ask what can they do?

 

The answer is that at this stage there is no cure for kauri dieback.  But there are sensible precautions we all can take.

The main vector for kauri dieback disease is dirt on the feet of people or animals.  Or water running down from an infected area.

Kauri dieback spores are microscopic - you can't see them. They live for years in dry soil. Dirty boots, tyres or tools that you used years ago in an infected area could bring kauri dieback into your place.

To keep your favourite kauri safe, you and your neighbours will need to take the same precautions as visitors to kauri reserves.
 

  • Clean feet and paws and tools that have been offsite 

    • Clean any feet, paws, footwear, clothing, tools, bikes etc which have been on soil ANYWHERE outside your garden by

      • Washing them thoroughly in hot water and detergent - scrub off every spec of dirt in a bowl or tub

      • Tip the dirty water down the toilet or wash tub so it goes to the sewer - don't tip it on the lawn, path or down a stormwater drain - or you'll spread any spores.

    • Make sure your friends, family, tradespeople and other visitors are aware of this.  

    • Ensure that any builders, drainlayers, etc are fully aware that they should take full precautions to avoid the risk of spreading kauri dieback.

  • Keep away from kauri

    • Do not go closer to a kauri than "3 times the width of the dripline" - this is the likely rootzone - where the roots are much more vulnerable to the dieback spores

    • If necessary, fence the area off

    • Keep any visitors and pets away from kauri trees or from slopes up hill from kauri

    • If you must go closer to the kauri, undertake the Council's "phytosanitary" precautions -  email Pest Free Kaipatiki about hygiene training

  • Undertake pest control with your neighbours

  • Check the kauri (from a distance) and report concerns 

    • Take a photo of the kauri with a telephoto lens and send it to the Auckland Council kauri team (see kauridieback website below)

  • Keep a record of your kauri; help create a map of all kauri

You can contact the Auckland Council direct for advice if you have kauri on your property:

If you see a tree in Auckland that looks suspicious (see below for typical symptoms), please email the details (location and photos) to the Auckland Council kauri dieback team at kauri@aucklandcouncil.govt.nz with a copy to info@pestfreekaipatiki.org.nz. Include the iNaturalist link if you have one.

Assistance with innoculating trees:

If you are a private landowner, see also kaurirescue.org.nz  for a community approach to innoculating kauri to improve their resistance to dieback.

Here's what they say about reporting suspected dieback on their Contact Us page:

 

  • You can also call the Kauri Dieback Programme hotline on 0800 NZ KAURI (69 52874) or email kauridieback@mpi.govt.nz for more information or to report a tree that looks unhealthy. 

    The programme team will send any reports of unhealthy trees to the appropriate council or land authority to manage.


    You can't tell just by looking whether a kauri tree is infected with dieback or not.
     

  • An infected kauri may show symptoms like yellowing leaves, a thinning canopy, dead branches or large lesions (areas of damage) near the base of the tree that bleed resin.

    However, symptoms like these might be caused by other factors – for example, drought or age. Infected kauri may appear healthy and not show any symptoms during early-stage infection for many years – and some never develop trunk lesions.
