LA FORÊT

Comment les forêts en transformation
redessinent les terres et les eaux au fil du temps

Les forêts canadiennes évoluent de façons qui ne sont pas toujours immédiatement visibles. Dans certains endroits, les paysages se transforment en quelques années. Ailleurs, les changements se manifestent plus lentement, influençant les systèmes d’eau douce et la régénération des écosystèmes pendant des décennies. Ces transformations façonnent les milieux naturels et révèlent ce que les forêts canadiennes peuvent nous apprendre sur un avenir en changement.

Les trois projets présentés ci-dessous abordent les changements forestiers sous différents angles. Ensemble, ils explorent les conséquences de la disparition des forêts anciennes, les effets durables de l’exploitation forestière sur les écosystèmes d’eau douce et les archives écologiques qui montrent comment les forêts et les feux ont façonné le paysage pendant des millénaires.

Annie Sakkab
Disposable Forests: The Boreal Forest Sacrificed for Softness

Dans certaines régions de la forêt boréale canadienne, l’exploitation forestière liée à des produits de consommation courante, comme le papier hygiénique, contribue à la disparition de certaines des plus anciennes forêts du pays. Ces milieux abritent des arbres centenaires et des écosystèmes qui ont mis tout aussi longtemps à se développer.

Annie Sakkab prépare un projet photographique qui explorera les liens entre la perte des forêts, les écosystèmes d’eau douce et les communautés qui en dépendent. Par la photographie et le reportage, elle examinera comment cette perte est vécue au quotidien et comment ses répercussions se font sentir bien au-delà des zones récoltées. En suivant ces liens, son projet cherchera à comprendre ce qui est en jeu lorsque des forêts anciennes et les sols qui les soutiennent depuis des siècles sont transformés en produits à usage éphémère.

Dalal Hanna
The Legacy of Forestry on Freshwaters

TL’exploitation forestière peut laisser une empreinte durable sur les écosystèmes d’eau douce. Dalal Hanna dirige une étude pancanadienne sur les cours d’eau, analysant 100 sites où l’intensité et l’ancienneté de l’exploitation forestière varient afin de mieux comprendre comment ces écosystèmes réagissent au fil du temps.

Lorsque les forêts sont récoltées, les cours d’eau peuvent se réchauffer et les concentrations de nutriments se modifier, avec des effets qui se reflètent dans la qualité de l’eau et la diversité des espèces.

En comparant des bassins versants récemment exploités à d’autres récoltés il y a plus de 50 ans, le projet suit l’évolution de ces changements sur plusieurs décennies et contribue à la création d’un ensemble de données national reliant les pratiques forestières à l’état des écosystèmes d’eau douce à travers le pays.

Dorian Gaboriau
Deciphering the natural variability of past forest landscapes and fire regimes

Comprendre les changements climatiques et environnementaux actuels exige de remonter plus loin dans le temps.

Dorian Gaboriau recueille des carottes de sédiments lacustres dans l’est du Canada afin de reconstituer les conditions forestières passées et l’activité des feux. Ces archives naturelles permettent de comparer les dynamiques actuelles à la variabilité naturelle observée au fil du temps. Les couches de sédiments conservent des traces écologiques remontant sur des centaines, voire des milliers d’années, révélant l’évolution des forêts et des régimes de feu.

Les travaux de terrain se déroulent dans plusieurs régions de l’est du Québec, y compris sur des sites étudiés en collaboration avec des communautés autochtones dans des territoires encore peu documentés. Ensemble, ces données contribuent à mieux comprendre l’évolution des forêts et des feux au cours des 10 000 dernières années.

PROJET VEDETTE

LÀ OÙ LES FORÊTS PEINENT À SE RÉGÉNÉRER APRÈS LES FEUX

Ellen Whitman - Mapping Forest Vulnerability to Wildfire-Catalyzed Change

Les feux de forêt transforment l’Ouest canadien à un rythme et à une échelle sans précédent. Bien que de nombreuses forêts se soient historiquement régénérées après les feux, cette tendance change dans certaines régions.

Ellen Whitman a étudié comment les feux de forêt et le climat influencent la régénération des forêts d’altitude et des forêts nordiques, où les conditions limitent déjà la croissance des arbres. Dans ces milieux, la période qui suit un feu est déterminante, car les jeunes arbres doivent s’établir dans un environnement en changement.

Son équipe a mené des travaux de terrain sur un vaste gradient latitudinal, du sud de l’Alberta jusqu’au Yukon, en collaboration avec des partenaires autochtones et des organismes provinciaux. En comparant des sites brûlés et non brûlés, les chercheurs ont observé que certaines forêts se régénèrent comme prévu, tandis que dans d’autres secteurs, la régénération est limitée, voire absente, et la végétation est remplacée par d’autres communautés végétales.

En combinant observations de terrain, données climatiques et télédétection, le projet permet d’identifier les secteurs où les forêts sont les moins susceptibles de se rétablir après un feu. Les résultats mettent en lumière des régions où la régénération pourrait ne plus suivre les modèles historiques et où les paysages pourraient se transformer en de nouveaux types d’écosystèmes, contribuant ainsi à la planification et à la gestion des forêts. Lorsque les forêts ne se rétablissent pas après un feu, les répercussions vont bien au-delà des arbres, touchant l’habitat faunique, le stockage du carbone et l’avenir des paysages de l’Ouest canadien.

SUBVENTION TREBEK

PREVENTING FOREST LOSS
WITH PROTECTED AREAS

TJ Watt – Exploring & Documenting BC’s Endangered Ancient Forests

In British Columbia, efforts to conserve old-growth forests are increasingly focused on protecting connected landscapes rather than individual sites. Through his Trebek-supported project, TJ Watt documented endangered ancient forests using before-and-after photography to show how quickly these landscapes are being altered. By returning to the same locations after logging, his photographs made visible the scale of change in forests that are otherwise difficult to access.

This work helped bring wider attention to old-growth forests through Watt’s role as co-founder of the Ancient Forest Alliance, where his documentation has informed efforts to protect threatened forests across the province.

Building on this foundation, TJ is now involved with the Nature-Based Solutions Foundation, which helps enable new protected areas through conservation financing and partnerships with Indigenous and local communities. The work has expanded from documenting individual sites to a broader conservation model, where communities play a central role in establishing and managing conservation areas. 

What remains after an old-growth forest is cut. In the Caycuse Valley, TJ Watt’s powerful visual evidence of forests that can take centuries to grow and only days to disappear.

Project Outcomes:

  • Before-and-after photography documenting forest loss in threatened old-growth landscapes

  • National and international media coverage expanding public awareness

  • Collaboration with Indigenous and land-based communities on long-term conservation

  • Development of a conservation financing model supporting new protected areas

  • Protection initiatives advancing ~200,000 hectares of endangered ecosystems

MEET OUR NEW GRANTEES

Each year, Trebek supports people exploring some of the most important changes taking place across Canada. Meet our newest grantees as they introduce their projects in their own words.

INTRODUCING THE 2026 GRANT RECIPIENTS

MICHAEL CHRISTOPHER BROWN
Sacred Balance: Climate Change & Co‑Stewardship in the Muskwa‑Kechika

The Muskwa-Kechika Management Area in northern British Columbia is one of the largest intact wilderness regions in North America—six million hectares of roadless mountains, rivers, and valleys that have been cared for by the Kaska Dena and other First Nations for thousands of years. At its heart flows the Kechika River, a vast corridor for wildlife like moose, caribou, and grizzly bears to move and adapt as the climate changes.

Nearly two decades after first photographing this region for National Geographic Magazine, I am returning to document how the land and its people are responding to accelerating climate shifts—warmer winters, melting permafrost, and changing wildlife patterns. Working alongside Kaska Dena Land Guardians, Elders, and youth, our project, Sacred Balance, will combine traditional knowledge and science to record this transformation through storytelling, including imagery, sound and mapping.

Together we’ll create a visual record of change which includes repeat photography, motion and audio, and the building of an interactive StoryMap that weaves maps, voices, and stories from the Kechika basin. Beginning with exhibits in Kaska Dena communities, the project will share how First Nations stewardship and ecological resilience intersect in one of Earth’s last great intact wildernesses.

A new source of earthquakes and tsunamis shaping Vancouver Island’s iconic west coast

Vancouver Island’s outer coast is one of Canada’s most iconic landscapes, but also its most important locus of earthquakes and tsunamis. It constitutes the northern ~300 km of the ~1,000 km-long Cascadia subduction zone, where the oceanic Juan de Fuca plate plunges beneath continental North America along a gently-dipping “megathrust” fault that surfaces ~100 km offshore.

Currently locked, the fault is being steadily loaded with tectonic strain that will be released in the inevitable next Cascadia earthquake and tsunami. However, since the last such event was in 1700 CE (well before modern observations), exactly what it will look like is unclear. An important clue can be found in our unexpected discovery of a surface rupture on Flores Island, in the Clayoquot Sound UNESCO Biosphere Reserve near Tofino. We hypothesize that the fault, which lies within the upper North America plate and is the first of its type recognized anywhere in Cascadia, was generated by a particularly large offshore megathrust earthquake, possibly the one in 1700 CE. This will be tested by determining the rupture age using a suite of field sampling and dating techniques and comparing it with the known chronology of megathrust earthquakes.

The project sheds light on a "worst-case scenario" Cascadia earthquake and tsunami, provides a vital benchmark for improving early warning systems and evacuation measures, and illuminates the tectonic forces shaping Canada’s Pacific margin.

Listening to whales: using hydrophones, drones, and AI to unravel killer whale communication dynamics

Killer whales live in tight-knit societies held together by sound. In Northern Resident killer whales, each pod has its own distinct dialect, passed down through generations, a remarkable example of non-human culture. Yet even after decades of study, we still don’t know what most of these calls mean or how whales use them to navigate their complex social lives.

This project brings together whale biologists and AI researchers to explore orca communication through a new, integrated approach. Using synchronized underwater recordings, drone footage, and machine learning, we aim to link specific calls to the behaviours, social roles, and group contexts in which they occur – and to understand how human ocean noise disrupts their vital interactions. By studying both fish-eating Northern Resident and mammal-eating Bigg’s killer whales, we can compare how communication strategies evolve across ecotypes with different diets, social systems, and vocal behaviours.

A successful 2025 pilot proved the feasibility of this approach under field conditions on the NE coast of Vancouver Island. Our next phase will expand this work, laying the foundation for a cross-population standardized framework for studying killer whale communication – work that connects to a planned parallel effort in Iceland. By listening closely to these whales, we will deepen our understanding of their cultural richness and help design and advocate for strategies to restore the quality of their acoustic environment.

RAQUEL ALFARO SANCHEZ
Tracking Climate-Driven Shifts in Canada’s Latitudinal Treeline

The transition from boreal forest to tundra in northern Canada, where forest cover becomes sparse and patchy, marks a sensitive ecological boundary where even small climate shifts can trigger major landscape changes. Yet, because of its remoteness, this treeline zone remains one of the least studied regions of Canada.

With support from the Trebek Initiative, Raquel will navigate the Coppermine River in Nunavut to explore 469 km² of Canada’s northern treeline, studying how the dominant tree and shrub species are responding to a rapidly warming climate and determining whether the boreal forest is advancing northward beyond its current limits. This expedition will provide essential ground-based insight into how climate change is reshaping Canada’s northern ecosystems.

MONICA TAIS ENGEL
Water Bears and People on Canada’s Eastern Edge

People along the coast of Newfoundland and Labrador have been observing a rise in polar bears walking through backyards, breaking into cabins, venturing into hot tubs, and often posing a risk to themselves and pets. The ice is melting faster, and bears from the Davis Strait subpopulation are spending more time on land. They also have their migration routes crossing land and towns along the coast, so when not on water, they inevitably run into people. And this may cause problems for bears, coastal residents, wildlife managers, and policymakers. Coexisting with polar bears takes many forms, but without understanding what is happening in the region, mapping these interactions, and learning from past encounters, there will always be a blind spot in the decision-making process, and conflict will likely grow without preventive planning.

My project is exciting because it will be the first to document and map human-polar bear interactions in the region, combining evidence from historical and current media, interviews with people who have encountered bears and those managing these interactions. In collaboration with local residents, we will set up trail cameras on a small island just 15km from the coast of Newfoundland to look for a long-suspected but undocumented denning site. This discovery would have a massive impact on our understanding of critical maternal habitats in the Davis Strait and prove once more that we must listen to people and work together.

With a strong storytelling component, we will produce a documentary and deploy additional trail cameras near the communities to document bear sightings along their terrestrial migration paths. This project is also a perfect case for exploring when people stop being tolerant of polar bears, and conflict becomes an issue for managers, communities, and policymakers. It is about learning what it means to coexist with polar bears.

M’HAMMED KILITO
Confluences: A Human and Aquatic Cartography of the Laurentian System

Confluences is a photographic expedition following the 3,700-kilometre course of the St. Lawrence River from Lake Ontario to the Atlantic Ocean. Created in collaboration with local communities, it tells the story of those who live along the river and explores how they influence it and how it, in turn, shapes their lives. I will take a 4,100-kilometre road trip along its shores, photographing the life of its cities, the traces left by its industries, and the strength of the people who inhabit its banks. Canada’s greatest river stands at a turning point, facing the combined pressures of industry, climate change, and pollution.

The journey will begin in Kingston, where the river flows out of Lake Ontario, and will continue through Cornwall, Montreal, Trois Rivières, Québec City, the Gaspé Peninsula, Tadoussac, and Havre Saint Pierre, reaching the Innu community of Ekuanitshit, where residents experience ecological transformations firsthand and speak out about the changes they witness. It will end on the Lower North Shore and the Magdalen Islands, where coastal erosion and rising seas threaten people’s ways of life.

Along the way, I will meet individuals from many backgrounds, including workers, farmers, scientists, artists, and fishermen whose experiences together reveal how deeply our lives are connected to the river and to the landscapes that sustain us.

UPCOMING EVENTS

Through a new partnership with Exploring By The Seat Of Your Pants, Trebek Grantees are connecting with students through live virtual field experiences. Created by National Geographic Explorer Joe Grabowski, the platform has reached more than 1.5 million students in over 113 countries.

Our first Trebek sessions launched this spring, connecting students with grantees working across Canada. Additional events will return in the fall when schools are back in session. In the meantime, you can explore the recordings of two recent presentations below.

Wild Caving with Christian Stenner

Venture into some of the darkest and most unique places inside the Earth: Caves formed where glacier ice and volcanic heat interact, creating otherworldly environments that are both cold and hot at the same time. Christian Stenner has explored the largest and deepest of the world’s glaciovolcanic caves. Caves that tell us about volcanic activity and changing climate, the extreme microorganisms that can survive there, and how we might first find life on other planets.


Freeze the Future – Exploring Frozen Lakes with Andrew Budziak

Explore a hidden world beneath the ice. Canadian explorer, filmmaker, and wildlife photographer Andrew Budziak leads Freeze The Future, a project that takes divers beneath frozen lakes to study microscopic algae and understand how climate change is affecting freshwater ecosystems. Through film, science, and exploration, Andrew reveals that some of the most important discoveries can be found much closer to home than we might expect.

National Geographic Live brings leading explorers to audiences across Canada through a series of live events. These sessions extend fieldwork into public conversation, connecting audiences with the people and ideas shaping our understanding of the world.
