The Kauri tree (Agathis australis) is a large conifer native to New Zealand. It is known for its impressive height, often reaching up to 50 meters (164 feet) and a trunk diameter of over 4 meters (13 feet). Kauri trees can live for over a thousand years, making them some of the oldest living trees in the world. Their wood is highly valued for its durability and resistance to decay. Kauri trees grow in unique ecosystems, primarily in the northern regions of New Zealand. They play a crucial role in their environment, providing habitat for various species and contributing to soil health. However, they face threats from Kauri dieback disease, a soil-borne pathogen that affects their roots, leading to significant conservation efforts to protect these majestic trees.
