Researchers discover 84‑meter Taiwania fir, tallest tree in East Asia, in Taiwan's remote mountains

Researchers mapping Taiwan’s remote, steep mountain ranges have identified an unprecedented giant among the island’s ancient Taiwania fir forests. Using a combination of LiDAR aerial surveys and extensive citizen‑science investigations, the team located a Taiwania tree measuring 84.1 meters (276 feet) in height, establishing it as the tallest known tree in East Asia.

The discovery also revealed clusters of similarly massive specimens, described by scientists as “temples of giants,” where dozens of towering firs grow in close proximity. These dense stands are situated in some of the most inaccessible forested valleys, where years of arduous field expeditions were required to verify the trees’ dimensions and health.

Ecologically, the newly documented forests rank among the world’s most carbon‑rich ecosystems, storing substantial amounts of biomass in their massive trunks and extensive canopies. The findings underscore the importance of preserving Taiwan’s high‑elevation woodlands, which serve as critical carbon sinks and habitats for a range of endemic species.
