Yes, they are lovely trees, but if they are looking at the world's biggest trees, I wonder why the ancient kauri tree known as Tane Mahuta, king of the forest, in North Island, NZ, wasn't included. This tree has reached the age of 1500 years, is more than 51 metres high and has a girth of 13.7 metres. Kauris have been cut down in the past for building Maori canoes and homes; and by European newcomers for the timber trade. Now the emphasis is on conservation.
