For Mother Earth"s big day, we"re shining the spotlight on a tree known as "Father of the Forest," or Te Matua Ngahere in the Maori language. This giant kauri tree lives in the Waipoua Forest of New Zealand"s North Island. At more than 1,500 years old and more than 52 feet around, it"s one of the oldest trees in New Zealand and one of the largest. It"s long been revered by the Maori, and is protected by Maori elders.
