The Mother Tree

Suzanne Simard

Suzanne Simard came to realize that there was much more to a forest ecosystem than anyone had ever known. Or even considered. She learned this when she realized that trees were relaying messages back and forth to each other through “a cryptic underground fungal network.”

 

Through that underground fungal network there was “a clandestine path of conversations.” They conversed about dangers each tree had seen and how they might counter it. This sounds like science fiction, but it is science. She found the network was pervasive through the entire forest floor and connected all trees in a constellation of tree hubs and fungal links. She was able to discern,

 

“a crude map revealed, stunningly, that the biggest oldest timbers are the sources of fungal connections to regenerating seedlings…that connect to all neighbors, young and old, serving as lynchpins for a jungle of threads and synapses and nodes…the journey that revealed the most shocking aspect of that pattern—that it has similarities with our own brains. In it, the old and young are perceiving, communicating, and responding to one another by emitting chemical signals. Chemicals identical to our own neurotransmitters. Signals created by ions cascading across fungal membranes.

The older trees are able to discern which seedlings are their own kin.

The old trees nurture the young ones and provide them food and water just as we do with our own children. It is enough to make one pause, take a deep breath, and contemplate the special nature of the forest and how this is critical for evolution. The fungal network appears to wire the trees for fitness. And more. These old trees are mothering their children.

The mother trees.”

 

This is a remarkable new way of looking at a forest.  And, of course, these insights are relevant to other systems as well. How much more can we learn about these other ecosystems? It is a remarkable way about thinking about the world. It ushers in an entirely new attitude to nature.

Intelligence of the Forest

Affinity, Books, Environment, Nature, New Attitude to Nature, World of ideas

Suzanne Simard  is a Canadian forestry scientist  who has become famous for her research on forest ecology which developed into work on plant communication and even intelligence. She is a Professor in the Department of Forest and Conservation Sciences at the University of British Columbia. She is the author of an astonishing book called Finding the Mother Tree.

 

Early on in her career as a forester, Suzanne Simard was struck by the fact that the land would mend itself when left to its own devices. She noted that her ancestors on the land in British Columbia “logged with a lighter touch.  Had they learned something modern foresters had forgotten? Did they have a better relationship to nature?

 

The key thing Simard realized in her work as a forester and later scientific studies was that trees were part of a forest system. They were part of an ecosystem. And the parts of that ecosystem were intricately interconnected. As she said, “I discovered that they are in “a web of interdependence, linked by a system of underground channels, where they perceive and connect and relate with an ancient intricacy and wisdom that cannot be denied.”

 

In the book she goes into fascinating detail about how she reached these startling conclusion on the basis of solid, though not uncontroversial, science. A foundational insight she gleaned from her studies was that “I uncovered the lessons of tree-to-tree communication of the relationships that create a forest society.” She admits that the science of this phenomenon was at first controversial, “but the science is now known to be rigorous, peer-reviewed, and widely published. It is no fairy tale, flight of fancy, no magical unicorn, and no fiction in a Hollywood movie.”

 

Her scientific research led her to entirely new way of looking at nature. As she said, “In this search for the truth, the trees have shown me their perceptiveness and responsiveness, connections, and conversations. What started as a legacy, and then a place of childhood home, solace, and adventure in western Canada, has grown into a fuller understanding of the intelligence of the forest.”

 

We must declare Peace with the World

Affinity, Nature, New Attitude to Nature

 

The temperate Rainforest of British Columbia is a wonder. I had the pleasure of spending 2 months there last winter. It took me a long time to appreciate all that rain. Nearly a year in fact. My bad.

Rachel Carson was one of the finest nature writers, besides really inventing the environmental movement. In her magnificent book, Silent Spring, Carson talked about “a relentless war on life.” That’s what I would say capitalism is. It really seems anti-life.

Suzanne Simard wanted to learn how we had gone so wrong. In my view, we, as a species, started out on the wrong foot, when we took the position that we were not a part of nature. It is out there and we can do with it whatever we want. Heidegger adopted a phrase from Nietzsche to describe that: “the will to power.”

Carson then asked us to consider something very profound: “The question is whether any civilization can wage relentless war on life without destroying itself, and without losing the right to be called civilized.”

Really Simard in a very different way deals with the same issues.

If we are part of nature, we will likely treat it more kindly. It’s time for a peace treaty. Not just in Iran. Everywhere. That would really be a new attitude to nature.

A very radical Theory

A while ago now I read a book that I have wanted to blog about for some time. It is time for me to meander in that direction.

The book is called Finding the Mother Tree, by Suzanne Simard. Simard has an amazing theory, which I think potentially has monumentally important consequences.  It really is a radical theory and it has been attracting both blame and praise. It might be the most important scientific theory since Charles Darwin. I recognize that this is an incredibly bold statement, particularly from someone who admittedly knows little about science and claims to like modesty.

Simard argues that trees show us that they live in a complex, interdependent circle of life in which forests are a system in which the organisms in it are connected to each other through underground networks. She claims that trees perceive one another, learn and adapt their behaviours, recognize neighbours and kin, remember the past, and help each other out. Simard believes, based on her scientific work, that trees have agency about the future, elicit and give warnings to each other, mount defences against attackers, and both compete and cooperate with each other.

Much of what she says is relevant for other ecosystems too.

She bases her theory on work she has done in the rainforests of western North America, particularly Canada. She places importance on the fact that at the centre of these underground networks are often Mother Trees which connect and sustain those around them.

 

If you consider these theories seriously you cannot help but change your attitude to nature. These ideas will force us to change our understanding of ourselves and the world in which we live.

 

I believe that Simard’s theory, though hugely controversial, is as radical and important as that of Charles Darwin. In fact, I consider my immersion into this theory as part of another journey I am on, namely, my religious quest in the modern world. How can that be?  I will explain but it will take some meandering.

Simard starts her book by talking about her work as a young botanist in the forestry industry of British Columbia. She found a world that was very different than she thought it would be. As she said,

“I discovered vast landscapes cleared of trees, soils, stripped of nature’s complexity, a persistent harshness of elements, communities devoid of old trees, leaving the young one vulnerable, and an industrial order that felt hugely, terribly, misguided. The industry had declared war on those parts of the ecosystem—the leafy plants and broadleaf trees, the nibblers, and gleaners and infesters—that were seen as competitors and parasites on cash crops but that I was discovering were necessary for healing the earth. The whole forest—central to my being and sense of the universe—was suffering from disruption and because of that, all else suffered too.”

 

This theory might be the path to a new attitude to nature, something I firmly believe, is urgently needed. from my personal perspective that is the point of this book and Simard’s radical theory.

I will continue to meander through this book and the forest she talks about.

Hummingbirds are Magical

Birds, Hummingbirds, Nature

The American PBS show Nature once had a special on Hummingibrds.   It was indeed special because the subject of the show, hummingbirds are really special. Hummingbirds truly are “a magical work of nature.” Science and technology have struggled to keep up with them. Some modern movie cameras have revealed amazing things about their flight.

Hummingbirds have not stopped evolving. They are like no other birds on earth. Or better yet, hummingbirds are like no other birds in the sky.

“The more we learn, the more fascinating they are.” It has been a great summer. So far.

 

Bedazzled

2024 Trip to Eastern Canada, Nature, photography, Wild flowers of Manitoba

 

I have photographed crocuses many times in the past. I have hundreds of crocus photographs.  I can’t seem to get enough of them. Every year in spring—it is almost the first sign of spring for me—around Easter time I get the urge to go again.  I must be obsessive compulsive.

Why do I do that? Well, I always think I can get a better shot. It is always possible to get better images. I see other images and I want to contribute too. There are always other conditions in which I could photograph crocuses.

For example, this year when I went out the flowers were covered with gorgeous huge water droplets!  I had never seen that before to that extent. I was bedazzled. As a result, they were unlike any I had seen before.

Moreover, this year I had a newer better camera when mine died last year. Perhaps this would help me to get better images? I thought so.

 

Of course, it is always important not to be overwhelmed by the technology. Never let the technicalities get in the way of the photograph. Ultimately, the technology is not important. The photographer is important. The subject is more important.

 

 

The brilliant English poet, William Blake got it right:

 

“To see a world in a grain of sand,

         And heaven in a wild flower,

         Hold infinity in the palm of your hand,

         And eternity in an hour.”

That sums it up. There is a heaven in a wild flower. Every flower is a piece of heaven.

I find heaven down here on earth. I find it in flowers. And birds. And trees. And skies. Heaven is everywhere. I find heaven in forest, on the plains, and even in mosquito infested bogs. If you don’t see it you are not looking. Or you are taking bad advice.

 A Crocus Hunt

Nature, Wild flowers of Manitoba

 

 

Today I went out on my first wild flower expedition in Manitoba this year. I went to Sandilands Provincial Forest, a very special place.  The day was cool and cloudy, but not very windy.  The light overcast skies were perfect for photography. Enough light to avoid a gray world but no shadows that create light that is too contrasty.  Modern cameras are a marvel but they can’t  handle a large contrast between dark and light areas in a photograph. A light overcast is perfect, and that is what I had. They really bring out the colours of the flowers.

 

Those droplets were sparkling like the crown jewels. Not only that. They were huge. I have never seen them so large. This was intriguing.

I also noticed that though most of the flowers were lying down, no doubt to stay away from the wind, or perhaps had been piled on by snow that had disappeared, as a result were not at their best. However, there were some adventurous specimens that stuck their lovely flowers toward the light grey skies sky. Most of the flowers enveloped their yellow feathery centres  like doting helicopter parents.

 

Yet a few adventurous flowers shyly opened up to the very cool sun, searching desperately for light while inviting insects. But largely the yellow centre were hidden. What a pity. This was disappointing but the sparkles were the exchange. I will just have to go back again on a warmer day.

This was a strange but stunning day of searching for flowers. These flowers were gems of colour.

 

The Prairie Crocus, which is what these flowers are called in Manitoba are not really crocuses at all. Just like that sensational bird, the Red Knot, is not red.  My grandson Nolan loves that fact. Well, the Prairie Crocus is not a crocus. It is an anemone.

Just yesterday I learned from Nature Norm that there are no Prairie Crocuses in the Tall Grass Prairie. That shocked me. It  is sort of like going to KFC and finding they don’t have any chicken. I think that might be because so much of the Tall Grass Prairie has vanished.  Less than 1% of it remains in Manitoba. And even at that some people think the The Nature Conservancy of Canada has acquired too much Tall Grass Prairie. I think it also might be because they like disturbed areas as they evolved with prairie fires and heaby grazers–bison.

 

The flower has 5 or up to 7 sepals.  Sometimes these parts are blue and other times tending to white. But it has no petals. The petal is a  separate part of the corolla or inner ring which is often brightly coloured Those are the lovely purple parts of the flower.

 

It is also interesting to me that they seem to prefer disturbed areas.  They like Manitoba ditches. Go figure. Even the infernal ATVs can’t scare them off.

And like so much beauty, these flower come with danger. They should not be touched let alone eaten. Their sap is downright nasty. It can cause skin to blister, and cause vomiting, tremors and even collapse. Don’t tangle with this beautiful flower! Some have used it to colour their easter eggs. Hence their scientific name, Anemone Patens.  It helps that they usually flower around Easter.

In my opinion it is one of the most beautiful flowers of Manitoba and a worthy choice for Manitoba’s provincial flower.  I also like the fact that it is tough. Its flowers can sometimes poke through the snow. Yet they are also extremely delicate.

 

This was a great day in nature. Life is good.

 

St. Mary River, Nova Scotia

2024 Trip to Eastern Canada, autumn, Nature, photography

 

This is a panorama shot of the St. Mary river consisting of about 8 images merged into one.

The St. Mary’s River in Nova Scotia was a delight I discovered about 10 to 15 years ago.  I was surprised by the beauty. So today I was not surprised.  I was confirmed in my high expectations. This is an area of simple, yet great, beauty. After all, it’s a river in a forest. What can be special about that?

The St. Mary’s River runs for about 250 km. (160 mi.) and drains an area of approximately 1,350 sq. km. it has 4 branches with 130 lakes. The river was named Rivère Isle Verte by one Canada’s premier explorers, Samuel de Champlain.  A fort in the area was also called Fort Sainte Marie when the French built it in the 17th century, but it was later taken over the English who changed the name of the fort and the river to English versions of the old French names. Sort of like Donald Trump who wants to change the name of the Gulf of Mexico to Gulf of America.  Little minds do things like that.

The river is one of the many east coast rivers that contain the extremely interesting northern Atlantic Salmon (Salmo salar) species.  This is the 3rd largest of the members of Salmonidae family behind the Pacific Chinook and Siberian taimen salmons. Sadly, it is now an endangered species. Most populations of salmon of are anadromous, meaning that they return up river to spawn where the offspring  hatch in natal streams and rivers but move out to the oceans when they grow older and mature. The adults then move seasonally upstream again to spawn.

But interestingly some populations only migrate to lakes and become “landlocked” and spend all of their lives in freshwater. So iot is not true that they must return to salt water. Some of them just choose to do so.  When the mature fish return to rivers and streams they change colour and appearance.

Unlike the Pacific salmon species, the Atlantic salmon can survive spawning and return to the sea to repeat the process again in another year. About 5-10% of them do exactly that, returning to the sea to spawn again. Such individuals grow to extremely large size.

The life stages of Atlantic salmon are the following: alevin, fry, parr and smolt. The first stage is the alevin stage when the fish stay in their breeding grounds and use the nutrients from their yolk sac. During this stage their gills develop and they become hunters. The next stage is called fry, where the grow and then leave their breeding ground looking for foodk so they move where more food is available. During this stage in freshwater they develop into parr where they start preparing for their trek to salt water.

 

 

Young salmon spend from 1 to 4 years in their natal rivers and when they are large enough they smoltify, which means their skins change colours from colours adapted to streams to colours adapted to the oceans. They also are subjected to endocrinological changes to adapt to the differences in fresh water to ocean water. When smoltification is finished, the young fish (parr) learn to swim with the current instead of against it. That behavioral change  allows the fish to follow ocean currents and find prey such as plankton or fry from other species of fish such as herring. Apparently during their time at sea they can sense changes in the Earth’s magnetic fields. Nature never ceases to astound

After a year of strong growth, they will move to those sea surface currents that lead the fish back to their natal rivers. It is believed by some scientists that they use their sense of smell to detect the “right” rivers as well. They don’t move thousands of kilometres as many have suggested, instead scientists have learned that they “surf” through sea currents. Only 5% of the salmon go up the “wrong” river. As a result, it is more likely that they stay close to the rivers where they were born when they are out to sea and swim in circular paths to do that.

Atlantic salmon have been severely affected by humans as a result of heavy recreational and commercial fishing as well as habitat destruction, all of which have affected their numbers. As a result serious efforts have been made to conserve including aquacultural methods, though those have also been criticized by environmentalists. 50% of farmed Atlantic salmon now come from Norway where the aquaculture has been most effective.

The natural breeding grounds of the Atlantic salmon are rivers in Europe and northeastern coast of North America in both the United States and Canada. In Europe they can be found as far south as Spain and as far north as Russia. Sport-fishing in Europe has been so popular that some of the species in Europe southern populations have been growing smaller. The distribution of Atlantic salmon is strongly influenced by changes in freshwater habitat and climate, particularly changes in water temperatures, which of course are affected by climate change.

When the salmon leave their natal streams they experience very fast growth during the 1 to 4 years that they live in the ocean. In the ocean they must face an ocean of predators including seals, Greenland sharks, skate, cod, halibut, and of course humans. Dolphins have been seen “playing” with salmon but it is not clear that they eat them.

Once the salmon are large enough to undergo the tough track back upstream to their natal streams, the stop eating entirely prior to spawning. It is believed by some scientists that odour allows them to sense when they are again in their natal streams.

 

You will not be surprised to learn that Atlantic salmon populations were significantly reduced in the United States and Canada after European settlement. Rivers were degraded by the activities of humans in the fur trade, timber harvesting, logging mills and the spread of modern agriculture. As a result, the carrying capacity of most North American rivers and streams was also degraded as the fish habitat declined. The historian D.W. Dunfield claimed in 1985 already that “over half of the historical Atlantic salmon runs had been lost in North America by 1850.” In Canada a bill was presented to the Canadian Parliament that called for the protection of salmon in Lake Ontario. In the Gulf region of Nova Scotia where we have been travelling 31 of 35 salmon streams and rivers were blocked off by lumber dams and as a result many watersheds lost all of their salmon.

Where humans come damage often follows.  Then when damage occurs humans learn to regret the error of their ways and sometimes make heroic efforts at great cost to change things back to the way they were. Could there be a better way?

Despite all of that such rivers are flanked by the incredible variety of trees of the eastern forest as shown by the incredible variety of the autumn colours.
