Description

Are trees social beings? Forester and author Peter Wohlleben makes the case that, yes, the forest is a social network. He draws on groundbreaking scientific discoveries to describe how trees are like human families: tree parents live together with their children, communicate with them, support them as they grow, share nutrients with those who are sick or struggling, and even warn each other of impending dangers. Wohlleben also shares his deep love of woods and forests, explaining the amazing processes of life, death, and regeneration he has observed in his woodland.

Wohlleben's anecdotes are engaging, but sadly his book contains only a few.

I had actually been avoiding this because I was leery of what looked like its blatant, unapologetic anthropomorphism. Its "woo woo" feel. The author describes forests as communities, trees as having friendships, personalities, parenting skills. He talks about the way they hear, feel, touch, talk. Even love. Really, it's enough to drive a person nuts.

But...as it turns out, Wohlleben takes this approach deliberately, in order to make his readers do one very specific thing -- let go of the instinctive hierarchy we all implicitly assume exists between the plant and animal kingdoms. And between humans, and all the rest of life on earth. So when he discusses the difference between a solitary tree planted in a park setting that rarely lives up to its potential girth or age and the tree in a forest setting surrounded by many others of the same species which lives longer and grows stronger, as the difference between being raised on the streets and being raised in a good stable family -- he's not exactly imposing human centric concepts on an oak tree. He's really trying to get the reader to view the plant world -- the tree world -- as something dynamic, sensitive and responsive to its own environment, participatory and engaged in that environment. And that is something that is surely true, even if the language of intention he often falls into makes me squirm.

But then, people tend to regard themselves as apart from the ecosystem. They are, one might say, unempathetic, blind and deaf to the pulse of other kinds of life. So they do not consider it a moral problem to, say, cut down a tree, because in a human's mind, they are not "hurting" anything. Wohlleben's book is basically an extended explanation and description of how someone hurts a tree-- and the forest -- by cutting it down. In the world of trees, the book would probably come with warning labels for graphic violence.

But it is all science -- all a detailed account of how a wounded tree attempts to heal itself, what happens if it can't, what happens when opportunistic species -- fungi, bugs, critters, (people!), exploit a weakness. And the science, it has to be said, is absolutely fascinating. Do you know, I never realized that the circulatory system of trees which brings water up and down the trunk -- explained to me in grade school as "osmosis and capillary action" -- is not understood? That neither osmosis nor capillary action can account for the amount of water that has to be pushed up sometimes hundreds of feet, gallons at a time. And in fact we just don't know how trees do it.

Wohlleben packs a lot of truly very cool scientific research into what is really a quick and very readable book, and if he is sometimes a little too speculative on what all that research is telling us, nevertheless he succeeds in what he set out to do: convince the reader that if we want to understand and be awake to the rhythms of life around us, then distinctions between plant and animal are arbitrary and not particularly useful.

In the woods just north of the house I grew up in lived a massive hemlock, about ten feet off the main trail. During winter the snow would pin its lower branches to the ground. If you tucked the collar of your coat up under your toque, you could sneak through the branches without getting too much snow down your back. Once inside those perimeter branches, you entered a different world. The frigid wind and cold was gone and the snow that made walking so difficult was less than an inch thick. Every time I walked that trail in the winter, I made sure to pause underneath that hemlock.

Trees have always fascinated me which is why I was quick to pick up German forester Peter Wohlleben's book. The Hidden Life of Trees is interesting reading. Did you know that trees can feed nutrients to the stumps of their fallen comrades, keeping the stump alive for centuries? Did you know that trees communicate with each other, warning their neighbours of pests?

Wohlleben convincing demonstrates that trees are far more complex organisms than we have understood. A fully functioning forest—forests that take five centuries to develop—are perfectly balanced examples of biodiversity.

Unfortunately, Wohlleben's fascinating information and observations about the forests are mixed with overly anthropomorphic ideas. You get the impression that Wohlleben has spent a little too much time in the woods alone! The Hidden Life of Trees walks the fine line between research and romanticisation, falling too often into the latter.

A well structured and easy read through a series of revelations after revelations of how trees interact with the space they occupy and with each other. Just managing to mostly side-stepping overt anthropomorphism. Once read you will never ever look at trees in the same light again. They will no longer be just a tree. The underlying theme that comes out so strongly is 'interconnectedness' of not just Nature in a broad brush sense but at every level down to the smallest cell, co-operating reacting or defending against other cells and back up to the big organism, plants, animals, man, trees, weather systems and the climate we all depend. All is connected. It is just that with trees the timescale is beyond our ready comprehension. their timescale is measured in our generations.

It is an easy read inviting you to glide along effortlessly as you are led deep and deeper into the marvels that are trees. This is then perhaps its weakness, to keep it easy reading it is light on the scientific support for claims that some might find startling,erring on the absurd. Do trees really talk to each other? The scientific justification is hinted at but with insufficient detail to be able to critic the soundness of the studies referred to. So a highly speculative romanticised look at trees or a well researched look combing all the latest evolving knowledge. Your choice, but I challenge you to walk past another tree and just dismiss it as a tree.

The Hidden Life of Trees is a fantastic little big book. It's little in length but big on new perspective and ideas. Originally published in German, Peter Wohlleben is an ex-forestry manager who decided to look beyond the typical knowledge of trees. He is a lifetime close observer who sees trees as a form of animal with memory, sensory input, paternal instincts. His basis is recent science.The other great thing is Wohlleben projects a sense of mystery about trees, he's like a Gandalf character speaking about the Ents, but always remaining grounded in the facts. Great stuff and great book.… (more)

a meditation on these companions we we have always had but often overlooked.
LibraryThing member ivan.frade
This books captures very well the complex interactions than make nature run. It explains how trees "work" and how forests are more than the sum of their trees. It manages to break down in short and easy to read chapters how fungus, animals, weather, different species help/fight/harm-but-not-too-much each other to form a resilient ecosystem.

I liked a lot the information exposed, the mix of research data with the "once you think about it, it makes sense" explanations and the easy-going tone of the book, but the excessive "personification" of the trees (specially at the beginning) made it difficult to take it more seriously.

Fascinating! Some of what he writes is hard to believe. Can't quite tell if wishful thinking stretches the science. But his ecology of coastlands makes all kinds of sense. I hope people who can adopt these practices are listening.

This is an excellent, if challenging book, on trees. I love trees and this is why I picked up the book. I have also been contemplating buying a book on the trees of Delhi by Pradip Kishen, and maybe I will.

Why do I say it is challenging? I say say because Peter challenges us in a gentle manner, to review our own beliefs of trees. In the beginning, I read the chapters with complete disbelief and incredulity and, then I asked myself what people thought before they were challenged to believe in the spherical nature of the Earth.

Once you allow yourself to go past this stage, then you open your senses to enter a world that is alien, magical and wholly believable.

An excellent book. I would only have loved some photographs. It is my hope that this lacuna is fulfilled in future editions.

You will never look at trees and woods with the same eyes again after reading this book: it literary opens your eyes and you become sensitive to features you had simply not been aware of. When first opening the book its popular language made me skeptical: it is however well researched, its sources are listed and an Index provided. It is a young research area and much more information about the lives of trees is to be expected in the future. Two small points: The drawing supposedly of a „Birch“ is never a birch tree; it looks like a tree of the genus ‚prunus‘. And, considering European readers of this American-English translation, temperatures should also be given in degrees centigrade and heights in meters. (VI-17)… (more)

Wow! A stunner of a book revealing secrets of how trees live long lives, and what causes them to die prematurely. I didn't know about and was amazed to learn of the 'social' network of support in a forest to assist each other with help from fungus and other organisms.

This gem of a book is rich in information that can be overwhelming to most readers. For me this means purchasing this book is a must because I've always adored trees, and this beautiful book already has and will continue to teach me more about how trees communicate, suffer, heal, and effect the environment and people.… (more)

What an incredible read! Wohlleben's book is absolutely brimming with enlightening details about the next of trees and forests. His experience raises so many questions about what we think we know about plants and nature in general. I'm eager to read what further research will reveal.

Peter Wohlleben manages commercial forests in his native Germany, which has given him the opportunity to amass a lifetime of observations of trees at all stages of their life cycles. His sole has also given him access to a huge body of research papers from all around the world.

The premise of the book is extremely simple, yet remarkable in its impact. Naturally occurring forests (as opposed to those generated principally for commercial yield) are highly connected, delicate networks, in which individual trees actively collaborate with each other. He cites examples such as African acacia. These are particularly vulnerable to giraffes, which will eat the higher placed leaves. The tree can sense this happening and responds by releasing a hormone which is borne by the wind to neighbouring acacia trees. These neighbouring acacia plants will then release a bitter tasting toxin into their leaves, which will deter the giraffes. Of course, evolution being the wonder that it is, giraffes have developed ways of countering this, starting with one acacia and then moving upwind, so that the warning hormone will be of no avail.

Wohlleben produces a vast array of equally amazing examples of trees’ proactive engagement with their surroundings, and the manner in which individual trees will interact with fellows, both within and beyond their own species, for the greater good of the wider forest.it is down to such constructive collaboration that some of the great ancient forests have survived.

Knowing precious little about the biology of trees I found this book fascinating, although it was not without its petty annoyances. Wohlleben is clearly very knowledgeable on his subject, but seemed unsure whether he was writing for an equally well-informed audience or for people like myself who are largely ignorant of the technicalities of botany. This led to an irritating mix of the scientific with the patronisingly chatty, which I found simply irritating. I would have preferred a straightforward, technical account, without attempts at happyish humour with talk of tree love happening every year, or other syrupy attempts to make the book humorous. I was certainly left wondering whether all the critics whose encomia were splattered all over the cover had read the same book as me: this was an enjoyable and informative volume, but fell rather short of being ‘a paradigm-smashing chronicle of joyous entanglement’, as Charles Foster asserts!

Trees are people, forests are community. This book is for anyone who loves green beings. Trees aren't so different than us.
LibraryThing member Gwendydd
This has the potential to be an interesting book, but suffers from some major flaws.

I am usually annoyed by scientists' reluctance to anthropomorphize their subjects, but this guy takes it way too far. He takes anthropomorphism to an extreme when talking about trees, which not only makes him sound totally koo-koo, but also, I think, does a disservice to the variety and ingenuity of nature. By reducing trees to humans, he disregards how amazing it is that completely different organisms can behave in ways that seem so alike and yet are not.

Wohlleben's other annoying habit is that he is often talking about his own specific forest, but he makes it sound like he is talking about all trees in the world. He apparently lives in a part of the world where trees grow really slowly. I live in a part of the world where trees grow very fast. A lot of what he says about trees does not apply to trees in my part of the world.

If you're interested in the information in this book, I recommend that you read "What a Plant Knows" instead. That book is very scientific, and digs into the exact mechanisms by which trees and other plants communicate, feel, remember, and grow, and how we have discovered that plants do these things.

can trees feel? Can they think? A German naturalist will get you questioning everything you thought you knew about trees.

One thing's for sure: I'll never look at trees and forests in the same way again. The variety of means trees use to communicate with one another and the lengths they go to nourish each other is stunning, and while there will be doubts about whether this is done in any deliberate sense, the same thing might be said by alien species watching us from afar. Individual trees can learn, plan, and cooperate with others of their own kind . Do they have memory, emotions, intelligence? How would that affect the divisions we have laid on the natural world: plant, animal, and the in-betweens? Trees live on such a different time scale than us that our species, with our short lives and even shorter attention spans, can barely comprehend the patterns of behavior they share among themselves and with fungi, animals, and other inhabitants of the forest and ground.

How do we define a tree? By the area of it above the ground or below, where up to half of its biomass is hidden? There is a case to be made for considering at least some aspen groves as one individual, as with Pando, a clonal colony of a single male quaking aspen determined to be a single living organism by identical genetic markers and assumed to have one massive underground root system. The plant occupies 106 acres, and its root system, at an estimated 80,000 years old, is among the oldest known living organisms (adapted from Wikipedia). How are we to put this into our own context?

Before blooming, deciduous agree among themselves. Should they go for it next spring, or would it be better to wait a year or two? "Trees in a forest prefer to bloom at the same time so that the genes of many individual trees can be well mixed...When a pollen grain lands on a stigma, its genes are activated and it grows a delicate tube down to the ovary in search of an egg. As it is doing this, the tree tests the genetic makeup of the pollen and, if it matches its own, blocks the tube."

Despite all the planning done for storing up energy, producing young, etc., if the normal order of things are disturbed by weather, insects, overgrowth by other species, logging, or a plethora of other events, action can be taken by either the tree or an interdependent organism. For instance, lack of nutrients might cause a fungi to release a toxin into the soil to kill off a different type of organism and therefore release nitrogen to fertilize both tree and fungi.

"There are more life forms in a handful of forest soil than there are people on the plant." A tree without a forest is unable to take advantage of the life that would make it its healthiest, and it is doomed to a short existence (by tree standards, if not our own).

And here's something I didn't know, even surrounded by deciduous trees: leaf colors in autumn indicate what nutrients are being withdrawn back into the tree to help it winter over and plan for the following spring. Oaks (which surround my house) make use of every little scrap, which is why the leaves are just a dull brown by the time they fall.

Wohlleben's writing is geared to the non-specialist, and he has a sense of humor, too. Includes a note section and an extensive index.

I have absolutely no science background so I can't address the science behind the thoughts in this book. But, I do love being in the woods and I thought this book was great. It was jam packed full of really fascinating and interesting tidbits.
