Did you know that Spruce trees communicate during a solar eclipse?
Led by UWE Bristol Visiting Professor Alessandro Chiolerio, a team of scientists from around the world discovered the Norway Spruce trees (Picea abies) can anticipate and collectively respond to a solar eclipse. Detectable up to 14 hours before an eclipse, these trees shift from irregular, multi-patterned electrical signals to more stable and coordinated rhythms during the eclipse.
The study was carried out in the Dolomites' Val di Fiemme (Trento) at 2,000 meters above sea level, where trees were continuously monitored before, during, and after a partial solar eclipse.
This research has been published in Royal Society Open Science, as part of the pioneering “Cyberforest Experiment”, which combines tools from quantum field theory, complex systems science, and biological signal analysis to explore how forests behave as coordinated, living networks.
As we face increasingly extreme heat and drought, studying tree responses to stressors from solar eclipses to severe environmental changes provides vital insights. By exploring things such as chemical signals, sap movement, fungal networks, and other communication systems, we can better understand how trees cooperate and how we can support them, especially within an urban environment.
I wonder what Norway Spruce trees will be saying to each other tomorrow.
