Rebecca Hsu, a forest ecologist working at the Taiwan Forestry Institute in Taipei, is at the forefront of monitoring climate change effects through tree climbing data collection. Alongside photojournalist Dave Tacon, Hsu ventures into the lush forests of Taiwan to study the impact of climate change on the majestic trees that tower above the canopy.
The Thrill of Tree Climbing
Tree climbing is not for the faint of heart. Hsu describes the physical challenges of ascending tall trees, feeling the stretch in the rope as she bounces around and expends energy to reach the top. Despite the difficulties, she finds solace in the unique experience of being in the high tree canopy. The different light and wind patterns at such heights offer a perspective that is unparalleled on the ground.
In a photograph captured by Tacon, Hsu is seen abseiling down from the canopy of a giant Taiwania tree known as Great White. This specific tree, located in a forest at an elevation of 1,900 meters in northern Taiwan, is one of only 941 trees taller than 65 meters in the country. The age of such towering trees is challenging to determine due to their hollow nature caused by fungal rot. Instead, Hsu and her team rely on environmental disasters like earthquakes and landslides, occurring approximately once every 400 years, to estimate the age of these ancient giants. Great White, having survived two of these disasters, is estimated to be between 800 and 1,000 years old.
Research Focus and Data Collection
Hsu’s research centers on vascular epiphytes, plants that thrive on other plants without being parasitic. However, the Taiwan Forestry Institute’s broader research scope encompasses various aspects of plant life. Recently, they launched a four-year project investigating how giant trees are impacted by climate change, including the installation of weather stations in the canopy of Great White. This data collection marks the initial step in understanding the complex interplay between climate change and ancient tree ecosystems.
Venturing into the forest canopy is an adventure for Hsu, each tree climb revealing new discoveries and surprises. Despite having climbed Great White four times, she continues to uncover hidden treasures such as a rare species of lily, Heteropolygonatum altelobatum, flowering during her latest ascent. The thrill of exploration drives Hsu to delve deeper into the secrets of the forest canopy, shedding light on the intricate biodiversity that thrives high above the forest floor.
Implications for Climate Change
The data collected from the weather stations in the canopy of Great White hold significant implications for understanding the effects of climate change on ancient trees. As global temperatures rise and weather patterns shift, these towering giants serve as vital indicators of environmental stability. By monitoring changes in the canopy microclimate, researchers can gain insights into how these trees adapt and respond to the evolving climate conditions.
In a rapidly changing world where the impact of human activities on the environment is becoming increasingly evident, the work of ecologists like Hsu is crucial for preserving our planet’s biodiversity. Through innovative research methods and daring tree climbs, Hsu and her team are paving the way for a deeper understanding of the intricate relationship between trees and climate change.
In conclusion, the collaborative efforts of researchers and photojournalists in exploring the forest canopy shed light on the hidden wonders of ancient trees and their resilience in the face of environmental challenges. By scaling great heights and delving into the heart of the forest, Hsu and her colleagues are unraveling the mysteries of nature’s oldest inhabitants, providing invaluable insights into the impact of climate change on our planet’s fragile ecosystems.
