Temperature, Moisture and Freeze–thaw Controls on CO2 Production in Soil Incubations From Northern Peatlands
Resource
Peat accumulation in high latitude wetlands represents a natural long-term carbon sink, resulting from the cumulative excess of growing season net ecosystem production over non-growing season (NGS)...
The Biophysical Climate Mitigation Potential of Boreal Peatlands During the Growing Season
Resource
Peatlands and forests cover large areas of the boreal biome and are critical for global climate regulation. They also regulate regional climate through heat and water vapour exchange with the...
The Boreal-Arctic Wetland and Lake Dataset
Resource
Here we present the Boreal–Arctic Wetland and Lake Dataset (BAWLD), a land cover dataset based on an expert assessment, extrapolated using random forest modelling from available spatial datasets of...
The Hydrology of Interconnected Bog Complexes in Discontinuous Permafrost Terrains
Resource
In the zone of discontinuous permafrost, the cycling and storage of water within and between wetlands is poorly understood. The presence of intermittent permafrost bodies tends to impede and re-direct...
The Influence of Postfire Recovery and Environmental Conditions on Boreal Vegetation
Resource
Climate change is increasing the frequency and extent of fires in the boreal biome of North America. These changes can alter the recovery of both canopy and understory vegetation. There is uncertainty...
The Ongoing Lateral Expansion of Peatlands in Finland
Resource
Peatlands are the most dense terrestrial carbon stock and since the last glacial epoch northern peatlands have accumulated between 400 and 1000 Gt of carbon. Although the horizontal development...
Threatened Québec caribou herd expecting up to 12 calves this year
News
Organization
All twelve of the breeding-age females in the enclosed Charlevoix caribou herd, located northeast of Québec City, are believed to be pregnant. The herd was placed in enclosures in 2022 as part of a...

Organization:
Project Description: Dismantling 76.5 km of forest roads. We test different techniques including soil preparation, water course crossing removing and planting four species of trees. It was to test the...
Unexpected Greening in a Boreal Permafrost Peatland Undergoing Forest Loss is Partially Attributable to Tree Species Turnover
Resource
This resource is available on an external database and may require a paid subscription to access it. It is included on the CCLM to support our goal of capturing and sharing the breadth of all...
Untangling Effects of Human Disturbance and Natural Factors on Mortality Risk of Migratory Caribou
Resource
Abstract Human disturbances are rapidly increasing in northern and Arctic regions, raising concerns about the recovery and persistence of declining caribou ( Rangifer tarandus) populations. Yet, the...
Variation in Photosynthetic Properties Among Bog Plants
Resource
Plant functional types (PFTs) are used to make generalizations in modeling how plants impact ecosystem functioning. In boreal bogs the number of plant species is small, but several PFTs are...
Video - Aerial Survey of the George River Caribou Herd - July 2020
Resource
A 15':30" movie of a powerpoint presentation on the 2020 survey of the George River Caribou herd. The survey estimates the herd is up to 8,100 from 5,500 in 2018. Most of the increase is thought to be...

Water for the Futures We Want - Opportunities for Research, Practice, and Leadership in Achieving SDG 6
Resource
Canada and the world are faced with unprecedented water-related challenges which impact our ability to meet many of the UN sustainable development goals. Climate warming and human actions are altering...
Water Level Drawdown Makes Boreal Peatland Vegetation More Responsive to Weather Conditions
Resource
Abstract Climate warming and projected increase in summer droughts puts northern peatlands under pressure by subjecting them to a combination of gradual drying and extreme weather events. The combined...
Webinar - Forecasting Climate-sensitive Landscape Change Reveals Habitat Shifts and Population Uncertainty for Northern Boreal Caribou
Resource
Climate-induced northern forest change may be severe, altering resources for boreal caribou. Mitigating the conservation challenges associated with caribou could be dampened through forecasts of...
