Experience: I climbed the tallest tropical tree in the world
A conservationist from Tawau, Malaysia, shares his journey from logging camp upbringing to scaling the world’s tallest tropical tree in Borneo’s Danum Valley. He details the technical climb, encounters with wildlife, and the scientific importance of canopy research.
In the heart of Borneo’s Danum Valley, a 100‑meter‑tall yellow meranti stands as the tallest tropical tree on Earth. The story of how a young conservationist from Tawau, Malaysia, reached its summit is one of determination, scientific curiosity, and a deep respect for the forest.
From Logging Camps to Conservation
Born in the coastal city of Tawau on Borneo’s east coast, the author grew up amid logging camps where his father worked. The early 1990s saw large swaths of the island’s rainforest cleared for commercial development, a reality that seemed inevitable to the boy at the time. That perception shifted when he began volunteering with the South East Asia Rainforest Research Partnership in Danum Valley during his teenage years.
His early tasks involved planting seedlings in clear‑cut areas, a hands‑on introduction to the importance of forest regeneration. By 19, he witnessed colleagues scaling trees to measure heights and install wildlife cameras—a niche yet vital part of ecological research. Despite a fear of heights, he felt drawn to the canopy, recognizing that most conservation work occurs on the forest floor while the canopy remains largely unexplored.
Discovering the World’s Tallest Tropical Tree
In 2018, researchers from the University of Nottingham identified a yellow meranti tree in the valley that could reach 100 metres. A GPS coordinate was provided, but locating the tree required three to four hours of trekking through dense undergrowth. The team’s excitement grew as they approached the towering specimen, its trunk rising like a silent sentinel above the surrounding forest.
Three months later, in January, the climber organized a dedicated expedition. A crew of ten, equipped with 400 metres of rope, fishing line, and a rope‑walking system, prepared for the ascent. Two climbers, including the author, wore harnesses and walked along the rope, moving from branch to branch while a third team member held the other end of a tape measure to record height increments.
The Ascent: Challenges and Triumphs
Climbing a tree of this magnitude is far from a simple hike. The author recounts pausing at every branch to assess its strength, checking for snakes, scorpions, wasps, and other insects. An encounter with aggressive bees left him with a hundred stings and a brief fainting spell upon descent—an experience that taught him to avoid bright colours in future climbs.
At 70 metres, the view shifted from the forest floor to a vast canopy that stretched like a green sea. The isolation intensified as the tree towered 50 metres above its neighbours. To maintain visibility, ground crew wore orange helmets, appearing as tiny ants from the canopy. The climber’s fear subsided as the landscape opened up, revealing layers of foliage, cloud‑piercing branches, and a serene, almost otherworldly atmosphere.
Reaching 95 metres, the branches became too thin for safe passage. The final push involved a pole to tap the top, confirming a height of 100.8 metres. The descent was swift, but the experience left an indelible impression of the forest’s grandeur and the quiet calm of the canopy.
Scientific Impact and Future Work
Beyond the personal triumph, the climb served a scientific purpose. The author and his colleague installed cameras to monitor wildlife and gather data on the canopy’s microclimate. Subsequent climbs were faster—about forty minutes—thanks to experience and improved equipment, yet each ascent reinforced the importance of canopy research in understanding forest dynamics and biodiversity.
For the climber, every tree tells a story of history and ecological resilience. The experience underscores the need to preserve these towering giants, not only for their ecological value but also for the unique perspective they offer on the world’s largest rainforest.
Looking Ahead
While the author’s next climb is already planned, the broader goal remains clear: to raise awareness of Borneo’s forests and inspire conservation efforts worldwide. The towering yellow meranti stands as a testament to the forest’s resilience and a beacon for future research.
In a world where tropical forests face relentless pressure, stories like this remind us of the delicate balance between human ambition and environmental stewardship.
Why it matters
The climb highlights the critical role of canopy research in understanding tropical forest ecosystems and underscores the urgent need to protect Borneo’s remaining forests from deforestation and exploitation.
