And if all of that wasnt impressive enough, the average lifespan of this tree is anywhere between 600 to 1000 years old. From this place of clarity, we can take the necessary action needed to create a healthy environment for growth. The bark of a kauri tree grows in smooth flaking sheets. [17] One 1700 year old swamp wood kauri that dates to approximately 42,000 years ago contains fine-scale carbon-14 fluctuations in its rings that may be reflective of the most recent magnetic field flip of the earth.[18]. clean of parisites.

Sailors quickly realised the trunks of young kauri were ideal for ships' masts and spars, and the settlers who followed felled the mature trees to yielded huge quantities of sawn timber of unsurpassed quality for building. This results in a large buildup of litter around the base of a mature tree in which its own roots feed. While they played a major role in the destruction of the forest, they were also impressive engineering feats, built without drawings or detailed calculations, yet able to withstand the pressure of tonnes of water and kauri logs which were swept through with tremendous force when the dam was tripped. If no anatomical adaptations take place, the horizontal sap flow presumably occurs via existing vascular rays. This is because estimates of the total carbon content in living above ground biomass and dead biomass of mature kauri forest are the second highest of any forest type recorded anywhere in the world. New Zealand is deploying dogs to sniff out a deadly disease that is causing havoc to ancient kauri trees in the North Island.. The tree's retreat can be used as a proxy for temperature changes during this period. forests", "Hydraulic Coupling of a Leafless Kauri Tree Remnant to Conspecific Hosts", "Trees share water to keep this dying stump alive", "Re-evaluation of forest biomass carbon stocks and lessons from the world's most carbon-dense forests", "McGregor, William Roy 18941977 Zoologist, university lecturer", "Phytophthora cinnamomi in indigenous plant communities in New Zealand", Groups join forces to fight kauri-killer fungus, Masters thesis on growth and yield of NZ kauri, https://en.wikipedia.org/w/index.php?title=Agathis_australis&oldid=1140632818, Moisture content of dried wood: 12 per cent. Kauri in Waima ForestImage: Sarah Wilcox | Creative Commons. They make up for their dallying by growing for a long, long, long time. Because the stands of kauri were dense, the ecological destruction in the affected plateau area (approximately a fifth of the forest by area, and a quarter by volume of timber) was essentially complete (as of the early 1990s most of the affected area contained a thick covering of native grasses with little or no kauri regeneration). It has been found in Northland, Great Barrier Island and the Coromandel Peninsula. These roots are necessary for the tree to stay upright and strong against wind and storm damage.

Its popularity with boatbuilders is due to its very long, clear lengths, its relatively light weight and its beautiful sheen when oiled or varnished. In fact, because kauri live so long and their leaves are high in tannins, they modify the soil they live on, and create specialised habitats such as gumlands.
