My Drive Across Canada: Part 2—Boreal Forest

The second leg of my drive west from Peterborough, took me past Thunder Bay, northwest from Lake Superior and into the heart of the boreal forest. Named after Boreas, the Greek god of the Northwind, the boreal forest is also called taiga (a Russian word from Yakut origin that means “untraversable forest”). Canada’s boreal forest is considered the largest intact forest on Earth, with around three million square kilometres still undisturbed by roads, cities and industrial development.

Canaada’s Boreal Forest

The boreal forest is the largest forest region in Ontario, covering two thirds of the province—some 50 million hectares—from the Great Lakes-St. Lawrence forest to the Hudson Bay Lowlands. 

I drove the Trans-Canada Highway (Hwy 17) through mixed coniferous forest, wetlands and marsh. The highway generally marks the boundary or transition zone between true Boreal Forest and the Great Lakes-St. Lawrence Forest, both dominated by coniferous trees.

I stopped at English River overnight and the following morning woke to the echoing calls of two loons on the lake. I left at dawn with a peach sky behind me and a dark charcoal sky ahead of me. Soon the dark clouds unburdened themselves and the rain fell in a deluge as I continued west, barely making out the dense forest through flapping windshield wipers. The forest here was a mix of balsam fir, white and black spruce, white pine, aspen and white birch.

When the rain abated to a steady sprinkle, I ventured out to photograph the spruce-moss-lichen forest by the side of the road. I stood in the drizzle and set up my tripod and camera to take my shots, careful not to tread on the reindeer lichen. Reindeer lichen is highly susceptible to trampling. Branches break off easily and they take decades to recover. This foliose lichen is a key food source for reindeer and caribou during the winter; it also helps stabilize soil and recycles nutrients.

I drove into the tiny community of Vermillion Bay on Highway 17, looking forward to stopping in Quacker’s Diner for a hearty breakfast as advertised by a fetchy sign on the road. Alas, the place had closed long ago, according to the lady at the Moose Creek Trading Co., and hadn’t been replaced. And she couldn’t suggest anything else in the village. Disappointed, I felt I was truly in the middle of nowhere…

Then, a ways down the main road, I spotted the sign: “Nowhere Craft Chocolate & Coffee Roastery” and felt like I’d entered a dream-state where the north was run by hipsters.

It was a husband and wife team who ran this wonderful craft bean-to-bar chocolate making and coffee roasting enterprise.

No sooner had I started to feel like I was back in trendy southern Ontario, when I met one of the locals, Simon, who worked in the bush and was patiently waiting for some dark roasts to take back to his buddies. We got to chatting and he shared some colourful stories about ‘the bush’ and folks who live in it, reminding me where I really was.

When I mentioned the experience to a friend, she made the astute comment: “It is somehow satisfying to think of loggers and trappers and campers emerging out of the forests to go have a great cup of coffee and a hunk of chocolate. Why does that seem totally normal for Canada?”

The Nowhere craft chocolate I bought—dark chocolate infused with ginger and Colombian coffee—was the best chocolate I’ve tasted this side of Switzerland. I bought some dark blends of Nowhere Coffee and continued my journey, happy despite no breakfast.

Black Spruce Forest

The black spruce (Picea mariana) dominates much of Canada’s boreal forests, frequently occurring in the Canadian Shield ecoregion where it forms extensive stands with groundcover of various mosses and reindeer lichen. Which of the two groundcover types depends on soil conditions and gaps in the forest from disturbance or fire.

The black spruce tree thrives in acidic peatlands, bogs and poorly drained mineral soils in wet, cold environments, but also grows in drier soils. It is particularly common on histosols (soils with peat and muck) on the Canadian Shield. Fires play a significant role in its regeneration as it replaces pioneer species such as white birch and tamarack after a fire, and grows with lichen and moss.

Mosses & Lichen Groundcover of Spruce-Dominated Forest

Both mosses and lichen (particularly reindeer lichen) help cool the forest by regulating evaporation and soil temperature; they can also fix nitrogen from the air, providing this key nutrient to an often nitrogen-limited ecosystem.

This spruce-moss woodland is typified by fairly dense closed canopy of black spruce (Picea mariana), along with white spruce (Picea glauca), balsam fir (Abies balsamea), paper birch (Betula papyrifera) and trembling aspen (Populus tremuloides); this association creates a fairly shaded environment on the forest floor, inviting groundcover of various mosses such as feathermosses and Sphagnum that thrive in stable moist, shaded conditions.

Common mosses in the spruce-dominated forest include Knight’s Plume Moss (Ptilium crista-castrensis), Red-Stemmed Feathermoss (Pleurozium schreberi), Glittering Feathermoss (Hylocomium splendens), and various species of Sphagnum. Knight’s Plume Moss and Sphagnum are key carbon cyclers in the poorly drained acidic boreal forest, contributing significantly to net primary productivity. They decompose slowly, leading to substantial organic matter accumulation.  Sphagnum in particular influences soil organic matter and carbon consumption during wildfires. Due to their ability to retain water, their acidity and resistance to decay, Sphagnum plays a crucial role in both the development and long-term persistence of peatlands where black spruce likes to live.

Spruce-lichen woodlands are characterized by an open canopy of black spruce trees, often with jack pine (Pinus banksiana) and white birch (Betula papyrifera) and a ground layer of mostly lichens, particularly fruticose species such as Cladonia rangiferina, C. mitis and C. stellaris.  This association is typically found on well-drained, often drier soils and may experience more extreme temperature fluctuations than spruce-moss associations. Through their release of acids that break down rock and organic matter, fruticose lichens contribute to soil formation.

A dense Cladonia mat also creates a microclimate that helps retain moisture. Lichen may also inhibit spruce regeneration, maintaining the open, park-like nature of lichen woodlands through the release of allelochemicals, such as usnic acid, that inhibit growth of plants and other lichen. Spruce-lichen woodlands may represent a stage in forest succession moving toward a closed-crown forest and may result from fire and insect disturbances that create openings in the forest canopy.

This is what I observed where I’d stopped the car by the side of the road; closer to the disturbance of the open road, reindeer lichens—likely Cladonia rangiferina, C. mitis and C. stellaris—formed a thick continuous mat on the ground, which was fairly open with young spruce growing here and there. Further up the slope, where the canopy became more closed with mature trees, the mosses dominated the ground.

Boreal Wetlands & Kabenung Lake

On my drive through the boreal forest north of Wawa, I encountered extensive wetlands—mostly marshes, bogs and fens, forming winding networks of water habitats. These water features are key to the environment’s water regulation, excellent carbon stores and provide habitat for many species. Boreal wetlands are seasonally or permanently waterlogged (up to 2 metres deep) with plant life adapted to wet conditions, including trees, shrubs, grasses, moss and lichen. Organic wetlands (peatlands or muskegs) such as bogs and fens accrue deep organic deposits. Mineral wetlands (marshes, swamps and open water) have shallow organic deposits; these open water systems have nutrient-rich soils.

I stopped at Kabenung Lake, considered a prime fishing lake, supporting diverse populations that include Northern Pike, Whitefish, Bass, Walleye, Brook Trout, Lake Trout, and Perch. Judging by the map, I had only a small view of the large convoluted 16 km long lake from the highway. The angler’s bathymetric map suggests a maximum depth of fifteen metres near the lake’s centre.

Before my journey west took me out of Ontario (and the boreal forest) into Manitoba’s flat prairie, I continued on the Canadian Shield across rugged terrain dominated by conifer trees with ancient Archean rock outcrops of granite and gneiss revealed in rock cuts on the highway. I reached Kenora, a charming old town with character architecture and a vibrant downtown. The town is located in the Lake of the Woods area, near the transition to the Great Lakes-St. Lawrence Forest to the south and the Aspen Parkland to the west. I saw lots of spruce, fir and pine alongside birch, maple and poplar. Lake of the Woods is a huge lake about 4349 km2 with over 14,000 islands with a highly convoluted shoreline and serves as an active hub for fishing, recreation and sightseeing.

In Kenora, I made a short stop at the craft brewery Lake of the Woods Brewing Company, bought some Sneaky Peach Pale Ale to take with me, and continued west to the Manitoba border.

On my way, I had to stop the car to let a red fox cross the road. It looked like it owned the road, just sashaying across in a confident trot and smiling at me…Yes, smiling!

The Sound of Snow…

Heavy snowfall where I live in Ontario (photo by Nina Munteanu)

I currently live in Ontario, Canada, where the four seasons are still distinct and winter comes with signature cold temperature well below zero degrees Centigrade along with lots and lots of snow. I grew up in Quebec, where the snow often piled up higher than I stood tall. Temperatures often went into the minus zero teens and twenties with wind chills reaching minus thirty degrees. This called for the right equipment. Insulated coat or jacket, snow pants, wool toque and mittens and/or gloves that are also well insulated. And, of course, warm snow boots.

Since moving to the West Coast then back east to Ontario, I’ve come to realize that I love winters. I love how snow covers everything, how it quiets the landscape and changes it in subtle ways. I love the frigid wind, how it bites the face with invigorating energy, reminding me that I am so alive. I love the sounds of winter, of walking on snow, crunching and squeaking, of the howl of the wind and the creaking and groaning of the trees, or the cracking and booming of the ice forming and reforming on the river.

I am currently finishing my fiction book Thalweg, which takes place throughout Canada, but predominantly in northern British Columbia and the arctic of the Northwest Territories. My main character, a Gwich’in scientist, explores the land during a time of climate change, and much of it involves the expansive vast snowfields of northern Canada in which she describes the look, smell, feel, and sounds of snow. She thinks with great fondness of home in the Arctic where snow prominently features and, bringing in all her senses, of course, includes sound:

There are many different kinds of snow, and any native of the north can recognize them. We can not only tell something of the quality of weather from it, but also its history. Without having experienced the day or history of the place, we will know simply from walking through it. For instance, on a minus twenty-degree Centigrade day, when the cold bites your face and your breath coils out of your mouth like steam, old snow shines under a raking sun like an ice sheet. As though clear plastic was stretched over it. Sometimes, a hoar frost will form on the glassy thin layer, adding more glitter. Walking through it creates a symphony of crunch, pop and skittle sounds as each step breaks through the thin brittle layer into soft snow underneath. The scattering flat shards tingle like glass across the glistening ice-snow sheet.

Fresh snow that has fallen on a frigid night of minus fifteen degrees in a drier climate is fluffy, individual snowflakes glinting like jewels in the sun, and emits a high-pitched squeak and crunch as your boots press down on it. The colder the temperature, the higher the squeak. I just made that up. I’m not sure if it’s true. But considering the relationship of harmonics with temperature, it’s plausible.

Squeaky snow is the snow of my home up north, where it arrives in a thick passion in October with the winter darkness, and where a constant minus 16°C to minus 30°C pervades until spring, six months later. The snow resembles powdered sugar, glittering like millions of tiny mica flakes under the moonlight of an arctic winter night. It covers everything, the ground, the trees and tiniest vegetation with a white blanket of snow. And when the wind teases the trees, they rain glitter-dust. In places where the north wind freely drifts across open landscape, sastrugi form; frozen wavelets, mini-barchans and dune chains that resemble the wave ripples of a sandy white beach. In some vast open areas, the wind will sculpt a frozen sea of irregular ridges and grooves up to a metre high. Mary’s friend Jem from Igloolik calls these snowdrifts qimugruk, whose distinctive shapes become permanent features of the snowscape, with tips always pointing west-northwest. Igloolik hunters use these uqalurait to set their bearings when travelling across the expansive tundra, particularly during poor visibility from storms or darkness.

One of the sensitivity readers for Thalweg, anthropologist and Gwich’in scholar Ingrid Kritsch, related to me an interesting account during attempts to open up to oil and gas development the Arctic National Wildlife Refuge–a critical area where the Porcupine Caribou herd calve. “To many Americans, it was just a big, white, barren expanse of unused lands,” said Ingrid. “She recalled a Senator speaking for development on these lands. The Senator held up a blank sheet of white paper and claimed ‘this is what the area looks like!’

The vast snowfields look nothing like that…
