More evidence that trees display group cognition and communication has arrived from the Dolomites where a multidisciplinary team monitored a forest during a solar eclipse. Their research witnessed two things, that the trees of the forest synchronized bioelectrical activity during the eclipse, and that the process of synchronization was started and directed by the eldest trees—a full 14 hours before the eclipse even started. The results of their experiment, which was published in Royal Society Open Science, demonstrate both the incredible value of old trees to the forests in which they live, but also the extent to which our woody cousins respond to their environment… The two older trees in the study, about 70 years old, had a much more pronounced early response to the impending eclipse than the young tree.
