Finding the Mother Tree - the connectedness of nature.

Review: Finding the Mother Tree, by Suzanne Simard 
 by Clement Kent 

Debuting in fourth place on the New York Times Best Seller list for hardcover non-fiction is not bad at all for a book on fungi and trees. Keeping me reading avidly throughout three hundred pages is pretty good. But changing the present and future course of how we plant, care for, and harvest trees will be the best impact of all for this book by UBC forest scientist Suzanne Simard. 

Suzanne Simard, from Radio Canada

I knew enough about Simard to buy two copies (from Indigo or your local independent bookstore), one for keeping and the other for circulating among friends. Although I normally relax by reading fiction, this was my sole reading material until I finished it. Simard’s storytelling mixes her life growing up in the mountains of British Columbia with the developing story of her scientific discoveries about how forest trees share support, warnings, and other messages with their neighbours via the underground network of fungi that go from the roots of one tree to the roots of the next. When she first proved that birch and fir in the BC forest can send carbon (as photosynthetically manufactured sugars) through fungi to each other in the most prestigious science journal in the world, the editors of Nature featured her paper on the cover and coined the phrase “the Wood Wide Web” to describe it. 

But the profound impacts of Simard and others’ work describing mutualistic relationships in the forest isn’t what will keep most readers going. Simard has written a very readable autobiography. Her family roots in the BC mountains as loggers and ranchers are lovingly described. Some of the climactic moments occur when her brother competes at rodeos. Family photos going back a century show what logging in BC used to look like, and Simard’s personal experience of how forests her own family had logged regenerated helped inspire her scientific questions. Going from early childhood (the scene in which the family dogs falls into the outhouse pit is a classic!) to young adulthood, motherhood, family crises and her life-threatening struggle with breast cancer and her mature life goals, the development of Suzanne Simard as a person, as a young woman fighting the scientific and forest business establishment, and finally as a central figure of modern forest science will engage you fully. 

To finish this review, I can’t do better than let Simard’s words from the last page of Finding the Mother Tree inspire you: 

We have the power to shift course. It’s our disconnectedness – and lost understanding about the amazing capacities of nature – that’s driving a lot of our despair, and plants in particular are objects of our abuse. By understanding their sentient qualities, our empathy and love for trees, plants, and forests will naturally deepen and find innovative solutions. Turning to the intelligence of nature itself is the key. 

It's up to each and every one of us, Connect with plants you can call your own. If you’re in a city, set a pot on your balcony. If you have a yard, start a garden or join a community plot. Here’s a simple and profound action you can take right now: Go find a tree – your tree. Imagine linking into her network, connecting to other trees nearby. Open your senses.

You need an artist to bring the science back to the way we live, to a human scale.

That's a quote from artist David Buckland, founder of Cape Farewell, a group promoting a cultural response to climate change. Long based in England, Cape Farewell is opening its North American office in Toronto with a benefit concert on Thursday November 10.

Why am I noting Cape Farewell's efforts in a blog on pollinator gardens? Well, pollinators depend on flowers and flowering dates are changing because of climate change. At the recent North American Pollinator Protection Campaign meeting in Washington DC, I heard a short presentation on this issue by scientist David Inouye. He has been tracking wildflowers and their pollinators for 40 years in the Colorado Rockies. There are many different stories of individual pollinator-plant interactions, but one example given by Inouye in a 2009 talk deals with the flower Erigeron speciosus and the Mormon Fritillary butterfly Speyeria mormonia. The butterfly is an alpine species and depends on alpine wildflowers. Inouye  and Carol Boggs of Stanford University have shown that earlier snowmelt in the Rockies is reducing butterflies, because flower buds are emerging earlier when frosts are still a high risk. As a result there are fewer flowers. Inouye has shown this trend for several early-blooming alpine flowers whose populations are declining. The pictures shown here (all from the 2009 talk) illustrate some of the flowers and pollinators.

These unexpected interactions aren't confined to the mountains.This chart from a research report by Simon Potts and colleagues shows how blooming time of blackcurrants in England (green circles) used to coincide with emergence dates of a key pollinator (red triangles) in the 1970's. Now the flowers bloom almost a month earlier than the bees emerge, reducing fruit set.

So, going back to Cape Farewell - climate change and pollinators turn out to have interesting and non-obvious overlaps. Explaining these to the public takes time, patience, and a gift for presentation that artists and media people have more than most scientists. That's why we as people interested in pollinators and their plants should be learning from Cape Farewell's example.

In another blog to be posted soon, I'll be asking you the readers about celebrities and pollinators.
