Agathis australis, commonly known as kauri, is a majestic coniferous tree found in the northern districts of New Zealand's North Island. It is the largest species of tree in New Zealand, standing up to 50 m tall, with a trunk diameter that can rival California sequoias. Kauri forests are among the most ancient in the world, with antecedents appearing during the Jurassic period. The tree has a unique ecological niche, feeding on the organic litter near the surface of the soil through fine root hairs and several downwardly directed peg roots. Its leaching process, important for its survival, leaves an area of leached soil beneath known as a cup podsol. Kauri is prized for its beautiful timber and long clear lengths, used extensively in boatbuilding. Protecting it from rot requires varnish, epoxy or paint. Kauri is also the best survivor of swamp conditions and is known as Swamp Kauri.
