Large Stocks of Peatland Carbon and Nitrogen are Vulnerable to Permafrost Thaw
Resource
Northern peatlands have accumulated large stocks of organic carbon (C) and nitrogen (N), but their spatial distribution and vulnerability to climate warming remain uncertain. Here, we used machine...
Łeghagots'enete ́, (Learning Together): The Importance of Indigenous Perspectives in the Identification of Biological Variation
Resource
Using multiple knowledge sources to interpret patterns of biodiversity can generate the comprehensive species characterizations that are required for effective conservation strategies. Caribou...
Mapping Smouldering Fire Potential in Boreal Peatlands and Assessing Interactions with the Wildland-Human Interface in Alberta, Canada
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...
Methylmercury in Managed Wetlands
Resource
Methylmercury (MeHg), a bioaccumulative neurotoxin, is microbially produced in anoxic wetland environments. The direct or indirect management of wetlands is pervasive, but many questions remain...
Preparing Variance Justifications for Reclamation Certification of Wellsites and Associated Facilities on Forested Land: 2023 Update
Resource
In 2021, PTAC sought verification of the Guide to Preparing Variance Justifications and stakeholders were asked to apply the document to current sites in their work portfolio.
Proceedings of the 13th North American Caribou Workshop
Resource
The 13th North American Caribou Workshop which was held in Winnipeg, Manitoba, was a great success with more than 400 participants: people from Canada, the United States, Norway and Greenland...
Recent Climate Change has Driven Divergent Hydrological Shifts in High-latitude Peatlands
Resource
High-latitude peatlands are changing rapidly in response to climate change, including permafrost thaw. Here, we reconstruct hydrological conditions since the seventeenth century using testate amoeba...
Revegetation of Post-mined Land Using Directly Planted Native and Local Shrub Species
Resource
Hand collecting vegetative propagules from surrounding pre-mined land and directly planting these propagules on post-mined land may be the only method to successfully establish key shrub species
Surface Soil Handling on Mines in the Boreal Forest – from Textbook to Operations
Resource
Research has shown forest surface soil provides an economical, diverse and abundant source of native propagules and an important source of nutrients and soil fauna. Salvage depth affects soil quality
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 Effects of Black Spruce Fuel Management on Surface Fuel Condition and Peat Burn Severity in an Experimental Fire
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...
The Essential Carbon Service Provided by Northern Peatlands
Resource
Northern peatlands have cooled the global climate by accumulating large quantities of soil carbon (C) over thousands of years. Maintaining the C sink function of these peatlands and their immense long...
The Unrecognized Importance of Carbon Stocks and Fluxes from Swamps in Canada and the USA
Resource
Swamps are a highly significant wetland type in North America both in terms of areal extent and their role in terrestrial carbon cycling. These wetlands, characterized by woody vegetation cover...
Towards a Shared Foundation for Innovation and Evolution
Resource
At the 2023 Alberta Chapter, Canadian Land Reclamation Association annual conference, Chris Powter, Tanya Richens, Andy Etmanski, Amanda Schoonmaker, and Dean MacKenzie participated in a panel...
Video - Can Woodland Caribou and Timber Production Coexist on the Boreal Landscape?
Resource
This presentation addresses some of the threats facing woodland caribou in the boreal, and the effects on wood supply.
Video - PTAC Knowledge Transfer Session: New Draft Wellsite Certification Guidance Documents for Sites in the Boreal Forest
Resource
Since 2018, InnoTech Alberta, Vertex Resource Group Ltd., Northern Alberta Institute of Technology, and Enviro Q&A Services have been working on a PTAC-sponsored project to provide recommendations for...
Whitewood Mine Closure
Resource
1665 ha has been reclaimed, including one end pit lake, numerous wetland features, woodland/wildlife areas revegetated through assisted natural recovery and perennially cropped agricultural lands
