As we competed for space and nutrients, the weakest of us died. At 25 years old, I became an adolescent, with a slender trunk and short branches that tapered to a narrow crown of leaves. My siblings and I stood shoulder to shoulder, keeping out other competing trees. As we thrust our way upwards towards the roof of the forest, we began shedding our lower branches. It took me the best part of 80 years to break out into the light. By then I had a tall straight trunk crowned by a ring of strong branches that I held high above the forest.

At the same time, the branches and bark platelets we continually shed were forming mounds of litter at our feet. Efficient recyclers, we extracted nutrients from our own shed skins to continue our growth in girth over many hundreds of years. Our litter is acid enough to exclude most other plants, helping us preserve this patch for ourselves. Shorter-lived trees and plants around our patch died and were replaced, but we lived on. We were now undisputed kings of the forest. Our crowns supported many other plants, forming a living garden high above the forest. Kokako sang from the tips of our branches and kaka nested in hollowed-out cracks in our trunks. After 500 years only a few of us were left, towering over the surrounding forest.
Key facts
Ancestors of the kauri first appeared in the Jurassic Period 190-135 million years ago.
Kauri forests are among the most ancient in the world.
Kauri forests once covered a million hectares of the north. Now only 7455 hectares of mature forest remain.
Waipoua Forest is the largest remaining kauri forest in the world.
3/4 of Northland kauri forest were felled between 1800 and 1900.
Younger kauri trees (rickers) carry short branches up their trunks until they are 120 years old.
