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...
Reindeer Lichen Transplant Feasibility for Reclamation of Lichen Ecosites on Alberta’s Athabasca Oil Sand Mines
Resource
This project is a pilot study to assess the viability of transplantation as a technique to establish reindeer lichens on reclaimed areas of oil sands surface mines in the Athabasca region of Alberta...
Restoring Drained Peatlands: A Necessary Step to Achieve Global Climate Goals
Resource
Peatlands cover about 400 million hectares (ha), or 3% of the land surface of our planet. Yet they store more carbon, more effectively and for longer periods, than any other ecosystem on land. Intact...
Revegetation of Tailings Sand Without a Soil Cover in the Alberta Oil Sands
Resource
Reclamation in the oil sands in Alberta is a high priority and can be challenging. Suncor Energy is in the process of reclaiming one of its consolidated tailings (CT) ponds (Pond 5). The CT is being...
Riparian Classification to Benchmark Reclamation of the Athabasca Oil Sands
Resource
A Riparian Classification and Reclamation Guide (‘Riparian Guide’) was recently produced to direct the re-establishment of riparian ecosystems in areas disturbed by oil sands mining in Alberta, Canada
Soluble Calcium and Sulphate Excesses Related to Stress in Pinus contorta on Peat Amendments of Reclaimed Landscapes in the Boreal Oil Sands Region
Resource
Results indicated a negative relationship among pine performance with increasing soluble calcium and available sulphate-S
Spatial and Temporal Variation in Forest Transpiration Across a Forested Boreal Peatland Complex
Resource
Transpiration is a globally important component of evapotranspiration. Careful upscaling of transpiration from point measurements is thus crucial for quantifying water and energy fluxes. In spatially...
The Effect of Cover Crop Species on Growth and Yield Response of Tree Seedlings to Fertiliser and Soil Moisture on Reclaimed Sites
Resource
Comparatively the suppressive effect of barley was higher than that of oats probably due to a combination of vigorous growth and possible allelopathic effects.
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...
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 - Demystifying the Methylene Blue Index
Resource
Dr. Heather Kaminsky is a Research Engineer with Suncor Energy. Her work involves understanding the behaviour of fine clay particles in the fluid fine tailings from Alberta's oil sands open pit mining...
Wet Pond Reclamation at Suncor
Resource
The issue of how to best manage the wastes resulting from the bitumen extraction processes is complex. When clays contained in the oil sands are subjected to the Clark Hot Water Extraction Process a...
