The TVO and National Film Board of Canada film Borealis by Kevin McMahon opens with ‘tree song’ and Diana Beresford Kroeger’s voice: “The design of Nature is music. If you listen to the trees, you will hear their song. And some people actually hear an individual song for certain species.”
Early in the film, you see Edmund Metatawabin, a Fort Albany First Nation writer, walking ghost-like in the forest. His voice tells us that when the trees look at us, we would just be like “these little things flitting by.” This simple comment underscores the difference that time plays to a tree that may live to a thousand years in contrast to a human who—if they are lucky—may live to a hundred. Says Metatawabin:
In a frank interview with Madeline Lines of POV Magazine about the making of Borealis, filmmaker Kevin McMahon talked about how the rugged beauty of the boreal forest belies a fragility poised on a precarious balance with humanity.
The film discusses some of the major relationships and mechanisms of this complex and unique ecosystem through the voices of scientists and naturalists who study and know the forest: botanists, population and aquatic ecologists, atmospheric scientists, forest entomologists and researchers and guides.
“The story of the boreal forest [is that] basically … it goes up, burns itself down and like a phoenix, goes up again,” says McMahon. “There’s a complexity—the trees influence the animals, the animals influence the trees, so a community grows up over at least two centuries, usually, and sometimes three, or four.”
One of the narrators tells us that the boreal forest has “survived and thrived in this regime of semi-regular stand-renewing fire.” This natural cycle of creative destruction is common in most ecosystems where destruction engenders rebirth and renewal by a community of species well-adapted to these cyclical changes. Botanist Diana Beresford-Kroeger adds, “the jack pine cones will only open on fire. The resin needs to be melted off the cone and then they shed their seeds.” The cones of tall spruce trees aggregate at the top of the tree, where the fire provides enough heat to open them but not burn them. White birch saplings sprout—phoenix-like—from the burnt tree base and roots. Aspen roots also send up thousands of suckers to become new clone trees of a renewed forest. The dead trees provide substrate for mosses, lichens and fungi that bring in moisture and decompose the logs into nutrients used by the living forest.
The movie showcases some of the most vivid details of tree function, including the microscopic view of opening and closing stomata (pores on a leaf). Stomata take in CO2 and release oxygen during photosynthesis. They also release water vapour as part of transpiration and other chemicals such as metabolic aerosols.
The devastation of climate change strongly features in the film as does our own mismanagement of the forests. A particularly telling scene was shot in the Yukon by Joshua See where squirrels have co-evolved with spruce trees in a relationship they’ve developed over 1000 years. The squirrels have timed their reproduction with the spruce production of cones and release of seeds; but climate change has knocked the trees out of sync with the squirrels, which is threatening the survival of the squirrel.
“I think that’s probably the first time any human being has seen such a vivid example of the rhythms of nature being thrown out of sync by climate change. And the funny thing is, if you listen to the climate change debate, as I obviously do fairly closely, that is something that has not really sunk in with the general public,” said McMahon. “People know about storms, and because of Australia and California they’re starting to learn about the impact it has on fires. But the reality that the rhythms of the world are all screwed up has not really sunk in, and Borealis has two really powerful examples of this. One is what happens to the squirrels, and the other is what’s happening to the trees, with what’s happening with the pine beetles.”
McMahon then adds soberly, “That last big dramatic drone shot [in the film] where you see that, basically, the boreal forest is dying – that’s Jasper National Park. This iconic forest that Canadians have sort of hung their identity on – you know, the snow-capped pine trees, and whatever – that forest is dying. It’s in a death spiral.”
McMahon admits: “I didn’t know when I started this project 10 years ago about the state of the forest. I was intending to make a film about how the forest worked. I did not realize until I started really talking to scientists that it is dying…The boreal forest is dying, and we are doing a super shitty job of taking care of it.”
This resonated particularly with me; I’d just published my latest eco-novel A Diary in the Age of Water with Inanna Publications. The novel—about four generations of women and their unique relationship with water—begins with a blue being in the unknown future as she runs through a dying forest of the north, the last boreal forest in the world…
McMahon adds a sober note about Canadian awareness:
“I think that in Canada – and this has been a theme of mine for decades – we pat ourselves on the back for being fresh faced boy scout-types, and we have this sense of ourselves as being green because we have so much green. The best thing about my career is I’ve been able to travel so much around this country. And it is a huge, huge country, and we do have just incredible, astonishing wilderness here–and we are wrecking it. We’re wrecking it in an extremely heedless, pointless, stupid kind of way. So I want that to sink in with people.
All those people at the end of the film that talk about the fact that the forest is collapsing, and we’re going to end up with a shrubland, and the forest emits more carbon than it sequesters–those are all Canadian government scientists. They’re not environmentalists. There’s no environmentalist voice in this film, in fact. I didn’t go to Greenpeace or any of those kinds of people, I went only to people who have a direct, material day-to-day interaction with the forest. Those people at the end of the film are on your payroll, and their job is to figure out what’s going. That’s what they’ve figured out, and I don’t think hardly anybody in this country knows that.”Kevin McMahon
But McMahon remains hopeful. He cites Ursula Franklin, a scientist and peace activist who said, “Despair is a luxury we cannot afford.” McMahon responds with, “That’s the model that I live by really, because if I didn’t have hope I wouldn’t bother making these films, I’d just retire.”
Near the end of the film, tree planter Isabella reminds us that, “We have the ability to make whatever it is that we imagine, so let’s just start imagining a new path, let’s start imagining a new way. We are so tied to this experience and whatever happens to that forest is going to be a reflection of what happens to us.”
The film ends with the powerful wisdom of indigenous writer Edmund Metatawabin:
