A team found the tallest tree in Taiwan. It is a special tree called Taiwania. The tree is very tall. It is 84.1 meters high. This is like a 20-storey building. People call it Heaven Sword of the Da'an River. The tree is very old. It is about 1,000 years old. The trunk is straight. It goes high into the forest.
Dr. Hsu leads this work. She works at the Taiwan Forestry Research Institute. Her team works for over ten years. They look at forests from the air first. Then they walk through hard ground to measure trees. Their work comes out this month in a science journal. The tree supports a whole ecosystem. Flying squirrels and owls live inside the trunk. Yellow flowers grow on the lower branches. Rare orchids grow in the upper part.
Big trees everywhere are in danger. The tallest tree in the world is in California. It is a coast redwood. It is 116 meters tall. A man named Chris Swanston works to save these trees. He says tall trees are like neighborhoods. Many species live in old trees. Old trees also help the air. They take in bad carbon gas.
