I read Peter Wohlleben’s The Hidden Life of Trees: What They Feel, How They Communicate - Discoveries from a Secret World (translated from German by Jane Billinghurst) as a sort of follow-up to Robin Wall Kimmerer’s Braiding Sweetgrass. Although they are coming at the question from different angles, both books make the same point that plants are, like, alive??

On the one hand, this is something that I think most people vaguely know. But it’s still startling to discover the plants communicate with each other through their root systems, and can send sugars through those roots so effectively that other trees can keep a tree trunk alive for centuries after its crown has died.

But this only occurs in trees in naturally occurring forests. When humans dig trees up to transport them and plant them where we want them, we sever the root tips, and trees never recover the ability to interface with other roots - even if there are other trees available to commune with, which there often aren’t if a tree is planted, for instance, alongside a street.

This helps explain why trees along streets and trees in tree plantations tend to be, in tree terms, quite short-lived. Also, Wohlleben points out, the qualities that humans consider “good” in trees are usually not the qualities that are actually good for trees. For instance, humans like to see trees growing fast, and sometimes point at the quick rate of growth in spruce plantations as proof that these plantations are actually good for trees.

But in fact fast growth is dangerous for a tree, as it creates structural weaknesses that will often kill a tree when it’s around a hundred years old. For human foresters, this is fine, as that’s about as long as we let plantation trees grow anyway, but from a tree’s perspective, 100 years is not a long time at all.

In Wohlleben’s view, humans struggle to understand trees because their perspective is so alien to ours. They’re stationary. Their senses and methods of communication are so different from ours that we struggle to believe trees have senses at all. (“In Wohlleben’s analysis, it’s almost as if trees have feelings and character,” says the incredulous author of this Guardian article, apparently unable to grasp that Wohlleben is arguing that trees DO have feelings, no “almost” about it.)

And, as Upton Sinclair pointed out, “It is difficult to get a man to understand something, when his salary depends upon his not understanding it.” The modern industrial lifestyle depends on seeing not just trees but the entirety of the natural world as raw materials we can dispose of as we will. Now, of course we’re capable of accepting that trees have feelings and then blithely refusing to change our behavior on account of that fact: after all, we do this with other humans all the time. But why bother embracing extra cognitive dissonance? It’s just easier all around if we continue to see trees as technically animate but more or less inert objects.
