save our world.: Kauri dieback






Kauri are among the world's mightiest trees, growing to more than 50 metres tall, with trunk girths of up to 16 metres and living for more than 2000 years. Kauri forests once covered 1.2 million hectares from the Far North of Northland to Te Kauri, near Kawhia and were common when the first people arrived around 1000 years ago.

Kauri dieback: how you can help

This webpage is the home for information on kauri dieback for the whole of New Zealand. It has information on what kauri dieback is, the symptoms of the disease and how you can help stop it spreading. You can also find our fact sheet, technical documents and links to the organisations involved in the management of the disease.
What is Phytophthora taxon Agathis?

Commonly known as PTA, Phytophthora taxon Agathis is a microscopic fungus-like plant pathogen (a disease causing agent) that only affects kauri. Recent research has identified PTA as a distinct and previously undescribed species of Phytophthora.
What does it do to kauri trees?

Symptoms include yellowing of foliage, loss of leaves, canopy thinning and dead branches. Affected trees can also develop lesions that bleed resin, extending to the major roots and sometimes girdling the trunk as a ‘collar rot'. PTA can kill trees and seedlings of all ages.

Kauri dieback: a disease that kill the trees.

I posted on my Sunday Stills a photo and asked my blogging friends to guess what it is. Many are curious.

Ed guessed right that it is a sterilser. When you enter and exit a place where there are kauri trees, you brush off the soil, and then spray some chemicals to your shoe.

I was going to post this in my Save the world meme when I saw this. So it is time to do it, and Ed was the first to know about it.

Some people don’t take this seriously, so we had an argument on our way home.

New Zealand takes Bio security very seriously. If you play golf, you have to declare it and clean your shoes very well.

I wish I have photos of the giant kauri to show you. I had been to kauri land, but I can't find the photos.

I'm glad they are taking it seriously, my guess was so far off!!!
