Do Trees Communicate?

Watch this fascinating video.

Another source of information about tree (and plant) inter-species communication that I highly recommend is Stephen Harrod Buhner's "Lost Language of Plants." His work focuses on the pheromone signaling shared within plant communities as well as the impacts of industrial chemicals (medicines, solvents, caffeine, but especially estrogen analogues) which are disrupting such communication pathways - even when found only in trace amounts "in the wild." He also discusses the notion of "mother plants" that act to establish a foothold in an environment, then providing (via chemical extrusions and physical mechanisms such as shade and humidity moderation) a more hospitable ecosystem for a wider plant community to develop and thrive.
