East Asia’s Tallest Tree Is the ‘Heaven Sword,’ an Environmental Guardian
Researchers used LiDAR and field surveys to confirm an 84.1-meter Taiwania fir after a decade-long search and a map of 941 giant trees.
Researchers identified East Asia's tallest tree, 'The Heaven Sword,' in a secluded valley in Taiwan, according to a study published Friday in the journal Frontiers in Forests and Global Change.
A group nicknamed the Taiwan Tree Seekers spent nearly 10 years surveying vegetation, using LiDAR technology and crowdsourced volunteers to analyze 57,065 candidate images to find the tallest specimen.
The Heaven Sword, a fir tree estimated to be about 1,000 years old, measures 84.1 meters tall and stands near the Da'an River in northern Taiwan.
Lead study author Dr. Rebecca Chia-Chun Hsu from the Taiwan Forestry Research Institute scaled the massive tree, using tape-drop measurement that confirmed the record height of 84.1 meters.
Taiwan's steep, mountainous terrain and stable oceanic climate create a rare environment sustaining giant trees, though the Heaven Sword remains shorter than the 116-meter Hyperion coast redwood in California.
Researchers in Taiwan call the "Heaven's Sword of the Da'an River" a cypress plant that is now named the highest tree in the region. An indigenous people has a different name for the botanical giant.
With laser scans, volunteers and laborious expeditions, researchers in Taiwan searched for tree giants. According to them, the "heaven sword" is the highest known tree in East Asia.
