Do trees have brains and talk to each other? They are intelligent, express emotions and make friends, claims a new book. Barking? Judge for yourself
Some research claims trees are able to communicate with each other
Forester Peter Wohlleben believes they are able to transmit information
Scientists are starting to ask whether trees possess intelligence and brains.
It sounds incredible, but when you discover how trees talk to each other, feel pain, nurture each other, even care for their close relatives and organise themselves into communities, it's hard to be sceptical.
Most individual trees of the same species growing in the same copse or stand will be connected through their root systems. It appears that helping neighbours in times of need is the rule, which leads to the conclusion that forests are super-organisms, much like ant colonies.
But the support they give each other is not random. Research by Professor Massimo Maffei at the University of Turin shows trees can distinguish the roots of their own species from other plants, and even pick out their own relations from other trees. Some are so tightly connected at the roots that they even die together, like a devoted married couple.
Diseased or hungry individuals can be identified, supported and nourished until they recover.
Every day in summer, trees release about 29 tons of oxygen into the air per square mile of forest. A person breathes in nearly two pounds of oxygen each day, so that's the daily requirement for tens of thousands of people. Trees don't care about us — but we should care about them.
