Kauri dieback is a serious disease affecting Kauri trees, which are native to New Zealand. This disease is caused by a soil-borne pathogen called Phytophthora Agathidicida. It attacks the roots of the trees, leading to their decline and eventual death. The spread of this disease is a major concern for the unique ecosystems that depend on these ancient trees. To prevent the spread of Kauri dieback, it is important for visitors to forests to clean their footwear and equipment before entering. Efforts are being made to raise awareness and protect these iconic trees, as they play a vital role in New Zealand's natural heritage.
