Kauri

Agathis australis · Araucariaceae · also New Zealand kauri

New Zealand's giant, a conifer typically 30 to 60 m tall with a smooth grey branch-free trunk 3 to 4 m (rarely 7 m) across and a huge spreading crown. Tāne Mahuta in Waipoua Forest is the most famous tree in the country. Logging and gum digging destroyed most kauri forest, and the soil-borne pathogen Phytophthora agathidicida (kauri dieback) now kills trees of all ages; the species is listed At Risk - Declining and is managed under a National Pest Management Plan.
