Biogeochemical Response to Vegetation and Hydrologic Change in an Alaskan Boreal Fen Ecosystem
Resource
Boreal peatlands store approximately one third of the earth’s terrestrial carbon, locked away in currently waterlogged and frozen conditions. Peatlands of boreal and arctic ecosystems are affected...
Buried Wood Effects on Macronutrient Supply and Microbial Activity and Metabolic Potential in Different Oil Sands Reclamation Soils in Northern Alberta
Resource
Buried wood is an important yet understudied component of natural and anthropogenic soils. Nutrient immobilization as a response to wood addition during oil sands' reclamation may be a concern since...
Effects of Elemental Sulfur on Soil pH and Growth of Saskatoon Berry (Amelanchier alnifolia) and Beaked Hazelnut (Corylus cornuta) Seedlings
Resource
The land disturbed by open-pit oil sands mining must be restored to support the survival and growth of native boreal plants. Because tailings sand and sodic shale overburden are commonly used as an...
Establishment of Native Boreal Plant Species on Reclaimed Oil Sands Mining Disturbances
Resource
Current revegetation strategies for disturbed oil sands sites include values such as biodiversity and sustainability. As a result, a wide range of species are sought for inclusion in revegetation...
Field Emergence of Native Boreal Forest Species on Reclaimed Sites in Northeastern Alberta
Resource
This study evaluated the effect of sowing season (spring versus fall) and propagule type (clean seeds versus whole fruit) on emergence of 41 species on oil sands mine reclamation sites.
Peat Loss Collocates with a Threshold in Plant–Mycorrhizal Associations in Drained Peatlands Encroached by Trees
Resource
Drainage-induced encroachment by trees may have major effects on the carbon balance of northern peatlands, and responses of microbial communities are likely to play a central mechanistic role. We...
The Third Generation of Pan-Canadian Wetland Map at 10 m Resolution Using Multisource Earth Observation Data on Cloud Computing Platform
Resource
Development of the Canadian Wetland Inventory Map (CWIM) has thus far proceeded over two generations, reporting the extent and location of bog, fen, swamp, marsh, and water wetlands across the country...

This is a hybrid seminar (in-person and virtual) sponsored by the Alberta Chapter, Canadian Land Reclamation Association. The presenter is Kira Gerow, a reclamation coordinator with Canadian Natural...
Translating the Closure Plan into an Operational Reclamation Programme at Canadian Natural’s Horizon Oil Sands Mine
Resource
Horizon Project reclamation goal is to achieve self-sustaining ecosystems with capability equivalent to predevelopment conditions using locally common boreal forest communities as a guide for reveg
Video - COSIA Design of Experimental Study in Support of Development of a Standard for Fines Measurement in Oil Sands
Resource
Dr. Ron Currie was project lead for a study conducted at NAIT Applied Research Centre for Oil Sands Sustainability (NARCOSS) to help develop a standard for Alberta's oil sands producers to measure...
Video - Flooding of In-line Flocculated Tailings After Thin Lift Drying
Resource
Dr. Aref Najafi is a Technology Development Engineer with Canadian Natural Resources Limited. He described the tailings research at CNRL as they develop an open-pit oil sands mine in NE Alberta. The...
