Researchers have identified what could be Australia’s tallest rainforest tree, a 77-meter hoop pine, in the Border Ranges National Park, located in Far North New South Wales. The discovery was made using advanced laser technology, and if verified, it would surpass the current record of 71 meters.
The tree was found during a comprehensive study aimed at mapping tree-canopy crowns and heights, as well as understanding influences on growth. This groundbreaking research is led by Patrick Norman from Griffith University and marks the first extensive use of Airborne Laser Scanning for forest canopy height in the region.
Unveiling the Giant
The hoop pine, situated near the Queensland border, stood out in the data collected from millions of trees across 3.1 million hectares in the Northern Rivers region. The project is part of a larger effort to develop climate change adaptation strategies for the Northern Rivers and the Wet Tropics of Queensland.
Patrick Norman expressed excitement over the discovery, stating,
“[The team was] very excited to see there was just one tree that really glowed in the Border Ranges National Park.”
Verification Process
To confirm the tree’s height, a ground expedition is planned. Dr. Norman is eager to undertake this task, noting the importance of verifying the laser data with physical measurements. “I’d love to do a ground truth where we can do some tree height measures from the ground and a little bit of drone work to build a 3D model from it,” he said.
If the initial measurements hold true, the next step involves a climber ascending the tree to drop a tape measure from the top, providing the final confirmation. “If the 77-metre is exactly accurate, we will try to get a climber to do the verification. They have to drop a tape from the top to give it the final tick,” Dr. Norman explained.
Implications and Context
While the hoop pine’s estimated height is remarkable for its species, it does not claim the title of the tallest tree in Australia. That honor belongs to a 99.6-meter mountain ash in Southern Tasmania. Nevertheless, this discovery adds significant value to the ongoing research and conservation efforts in the region.
The findings have been published in the Australian Journal of Botany, contributing to the body of knowledge necessary for effective environmental management and conservation strategies. This development follows a growing interest in understanding the impacts of climate change on forest ecosystems, particularly in biodiverse regions like the Northern Rivers.
Looking Ahead
The discovery of the hoop pine not only sets a potential new record but also highlights the importance of technological advancements in ecological research. As scientists continue to explore these remote areas, further discoveries may reshape our understanding of Australia’s natural heritage.
Meanwhile, the anticipation builds as researchers prepare for the ground expedition, which promises to either confirm a new record or provide valuable data for future studies. The journey to the tree is not just a scientific endeavor but a testament to the enduring allure of nature’s giants.
