Researchers recently climbed the world’s largest tree, General Sherman, located in Sequoia National Park, California, to inspect its health, specifically checking for damage caused by bark beetles. The 275-foot giant sequoia, estimated to be 2,200 years old, passed its health check with no signs of infestation by these insects. This inspection was led by Anthony Ambrose, executive director of the Ancient Forest Society.
The health of giant sequoias has been increasingly threatened by climate change, which has resulted in hot and dry weather conditions and severe wildfires. These environmental stresses weaken the trees, making them more susceptible to bark beetle attacks. Bark beetles, which were not a serious threat in the past, have killed approximately 40 sequoia trees in recent years.
To address this emerging threat, researchers are exploring new methods such as using drones and satellite imagery to monitor the trees. The health check of General Sherman was part of an initiative by the Giant Sequoia Lands Coalition, a collaborative group of government agencies, Native tribes, and environmental organizations. This coalition aims to establish a comprehensive health monitoring program for giant sequoias and to develop strategies for mitigating beetle infestations, including water and chemical treatments or removing affected branches.
The climb and inspection of General Sherman underscore the importance of ongoing research and innovative solutions to protect these ancient giants from new and evolving threats.
