1 . As the world’s oldest living organisms, trees have been our silent companions. Although they inspire a large quantity of fancy tales, the richness of what they say is beyond description.
The German forester Peter Wohlleben spent decades working and learning their secrets. Feelings are rarely applied to trees, but Wohlleben has done so without hesitation. According to Wohlleben, that humans do not speak the trees’ language does not mean they do not communicate. Trees are badly misunderstood even if they communicate with chemical and electrical signals.
Wohlleben claims that trees are creatures as human beings. In one of 50 cases, Wohlleben’s team sees the special friendships between trees, as they can distinguish between one individual and another. This means that trees do not treat all other trees the same. For instance, Wohlleben saw two old beeches standing next to each other. Compared to the usual case, each one growing its branches turned away from the other rather than toward each other. This kind of partnership is well-known to foresters. They know that such tree pairs are really like a human couple. If they chop one down, they need to chop down both because the other will die anyway.
Trees were also found to keep each other alive in different ways. They pass food to nearby sick trees and send signals to warn others of dangerous insects. In one of his investigations, Wohlleben also discovered a beech tree cut about 400 to 500 years ago. The trunk is still alive and was found with green chlorophyll (叶绿素) under the thick bark. Since it has no leaves to create sugar, the only explanation is that neighbouring trees have supported this tree for more than centuries.
The trees that suffered through drought were found to consume less water in the spring so that they will have more water available in the summer months. This implies that a tree can learn and remember a drought its whole life, acting on that memory by being more cautious about its water consumption.
