Dating back until at least middle school, I have wished I could see time lapse footage of root movement in a forest. Specifically, when my dad told me we couldn’t plant a Weeping Willow in our backyard because of their knack for finding water pipes and bursting them, it just seemed to me that trees weren’t nearly as static as we think they are. This thought was later built upon when I took an ecology and evolution summer class in college, and my professor explained that the trees are constantly fighting one another for sunlight, albeit so slowly that humans do not perceive it without something like time lapse.
So, these ideas had been on my radar for some time. However, when my sister sent me this video just prior to my departure, it blew my mind. It was exciting and magical, while tragically hopeless and sad about what we have destroyed.
If you found this interesting, there is a very interesting book that takes this topic from another interpretation: that the fungi (closer in DNA to animals than plants) is actually farming/herding the trees. It is called Mycelium Running, and while I have been unable to find a copy in Zambia I have heard a lot of great things about it from an impassioned fellow volunteer.
