For centuries, one of the most extraordinary living giants in Asia stood unnoticed among the remote mountains of Taiwan. Hidden within rugged forests and protected by difficult terrain, the colossal tree escaped scientific documentation despite its immense size. Now, after years of painstaking exploration, researchers have finally located and measured what is recognised as the tallest known tree in East Asia.Nicknamed the “Heaven Sword of the Daan River”, the giant Taiwania tree rises an astonishing 84.1 metres above the forest floor, making it taller than most urban skyscrapers and among the most remarkable trees ever documented in Asia. The discovery was not the result of chance. Rather, it resulted from the culmination of a decade’s worth of science involving advanced LiDAR scanning techniques, on-ground surveys, expert tree climbers, and ecology studies. The discovery gives a rare insight into Taiwan’s ancient forests, stressing their significance as centres of biodiversity and serving as a reminder that some of Earth’s biggest natural mysteries lie unexplored in far-flung locations.
How scientists found East Asia’s tallest tree hidden in Taiwan’s remote mountains
The search began in 2014 when researchers from Taiwan’s Forestry Research Institute, National Cheng Kung University, and the Taiwan Champion Trees project started mapping giant trees across the island using airborne Light Detection and Ranging (LiDAR) technology.LiDAR enables scientists to scan the forest areas using LiDAR to develop a three-dimensional map of the area. Using this technique, the scientists were able to detect hundreds of giant trees that were taller than 65 meters in height.According to the Taiwan Champion Trees project, the tallest giant Taiwania cryptomerioides tree was found near the upper parts of the Daan River after many years of analyzing and verifying its existence in the wild. Then, a difficult expedition had to be organized with the involvement of mountaineers, ecologists, geologists, remote sensing experts, and arborists.The tree’s measurements revealed that the tree’s height was 84.1 meters with a circumference of around 8.5 meters.Recording the journey in the form of a research article titled ‘The journey of finding the tallest tree in Formosa Taiwan,’ the researchers described their mission as a long-term effort to locate and document Taiwan’s remaining giant trees.“Since 2014, our dedicated group, the Taiwan tree seekers, has been on a mission to locate and document these sky-piercing giants,” said Rebecca Chia-Chun Hsu, Chi-Kuei Wang and Chung-Cheng Lee.
Why the Heaven Sword tree is one of Asia’s most extraordinary natural wonders
The newly documented giant belongs to Taiwania cryptomerioides, an ancient conifer species sometimes referred to as the Taiwania cypress. The species is considered a living relic of ancient forests that once covered large areas of East Asia.Researchers estimate that the Heaven Sword tree may be close to 1,000 years old. Towering above surrounding vegetation, it forms part of a unique old-growth ecosystem that supports countless plants, insects, fungi, birds, and other wildlife.Scientists involved in the expedition noted that Taiwan is one of the few places on Earth capable of supporting trees that exceed 70 metres in height.In their published account, the researchers wrote:“Taiwan is one of the rare locations on our planet capable of supporting giant trees, specimens that tower over 70 metres in height.”The discovery also highlights Taiwan’s remarkable forest diversity. Earlier surveys identified more than 900 giant trees across the island, demonstrating that Taiwan contains one of the most significant concentrations of large old-growth trees in East Asia.
What the discovery reveals about ancient forests, biodiversity and conservation
Apart from setting world records, this find holds great scientific value. The giant trees store carbon, stabilize soil, regulate local weather, and create ecosystems through habitat creation.In many cases, old-growth forests that house such giant trees hold decades’ worth of biodiversity data and can inform researchers of historical climates.According to the Taiwan Champion Trees research group, a lot of giants go unnoticed due to their remote locations that cannot be accessed easily. As such, modern technological advances such as airborne LiDAR play an important role in opening up access to these natural wonders that would otherwise go unnoticed.The find of the Heaven Sword should be viewed as a reminder that in the twenty-first century, there is still room for discovering something spectacular. In the mountainous regions of Taiwan, there are some of the oldest and largest trees found anywhere on Earth.
