Our peatland trading cards each showcase only one study conducted at that card's peatland (referenced below). These studies are a small subsection of various important peatland research in Canada.
In addition, Western peatland science lacks proper acknowledgment of and contribution from Indigenous Peoples even though the peatlands in Canada are largely located in the lands and traditional territories of many Indigenous Nations and have been safeguarded by these communities since time immemorial. Within Can-Peat, we aim to conduct ethical research by braiding Western and Indigenous Science and supporting Indigenous data sovereignty by working with Local Contexts. Regarding our trading cards, we are planning to release a series in collaboration with Indigenous Communities/Peoples focused on peatlands important to them in their languages.
To explore more past peatland research, watch out for the release of our Canadian Peatland Data Portal.

Series 1
001: St Charles-de-Bellechasse
Les tourbières sont connues pour leur capacité à stocker de grandes quantités de carbone dans le sol et à libérer du méthane. Ces fonctions peuvent être altérées par les effets du changement climatique tels que la baisse du niveau de la nappe phréatique.
En abaissant artificiellement le niveau de la nappe phréatique, les chercheurs ont découvert qu’une plus grande absorption de carbone par les plantes compenserait certaines des pertes de carbone induites par des conditions plus sèches.

002: Harmon Valley
Seismic lines, clear cut linear pathways created for oil and gas exploration, are prevalent in Alberta. Even after decades, the natural forest has not recovered in these areas.
This study found that changes in ground-layer plant community on the seismic line disturbance can contribute to slow tree recovery.

003: Bois-des-Bel
Disturbance from human activities can cause peatlands to release carbon into the atmosphere. Ecological restoration is recommended to reduce these emissions. However, peatland restoration can also produce emissions of the greenhouse gas (GHG), methane.
In this study, methane emissions remained low after restoration suggesting that peatland restoration can help mitigate GHG emissions.

004: Burns Bog
Canada is home to many peatlands. While much of our peatland area is intact, the largest raised bog on the west coast of the Americas, Burns Bog, has been significantly degraded.
In this study, Sphagnum colonies, important for peat formation, were found to be re-establishing following restoration efforts.

005: Mer Bleue
Northern peatlands are especially important in the global carbon cycle because they hold a quarter of the world's soil carbon. However, changing temperatures and precipitation under climate change may alter peatland carbon cycling.
In this study, carbon balances over 6 years at Mer Bleue were not significantly changed from historical records.

006: Pauciflora Fen
Les tourbières sont un élément important de l'hydrologie du paysage car elles fournissent de l'eau à de nombreux écosystèmes. L'eau dans les tourbières est stockée sous de multiples formes qui ne sont pas toutes bien comprises.
Dans cette étude, on a constaté que la glace souterraine saisonnière affectait l'hydrologie des tourbières, permettant à ces dernières de fournir de l'eau aux zones situées en aval au printemps.

007: Beverly Swamp
Ground and water temperatures in peatlands effect plants, animals, and energy balances. These important thermal regimes are in turn affected by human disturbances.
In this study, a model was developed and tested to simulate thermal regimes and can be used to predict response to disturbance across mid-latitude swamps.

008: Kirby
Canada’s boreal region is crisscrossed with seismic lines, long linear disturbances created for oil and gas exploration. Restoration efforts involve re-creating small-scale topography, e.g., 1 m high soil mounds. This may have unintended effects on soil properties.
In this study, changes in soil properties following restoration suggests carbon may be lost at the expense of vegetation recovery.

009: Robinsons Pasture
Peatlands are important to global carbon cycling, taking up carbon dioxide and releasing methane. Human activities, such as agriculture, may have impacts on peatland carbon cycling and its drivers.
In this study, methane emissions were near zero with changing seasonal drivers, like temperature and water table. Models will need to account for these drivers to estimate methane exchange in managed peatlands.

010: South Julius
Peat is extracted in Canada to produce growing media. Following peat extraction, peatlands are often restored via the moss layer transfer technique to re-establish carbon storage. While generally successful, this technique has had less success in fens.
In this study, active rewetting was found to be a potential alternative to the moss layer transfer technique in specific scenarios.
