Health of North American Forests
Resource
Forests are environmentally and economically important in North America, and forest health is monitored to enable policy decisions to be made on factors affecting forest health. Forests are subject to...
Heavy Metal Dynamics in the Athabasca River: Sediment Concentrations Prior to Major Alberta Oil Sands Development
Resource
To document the natural heavy metal geochemistry of the sediment and to assess cultural influences if any on concentrations. Absolute concentrations are low compared to data for polluted sediments
Heavy Metals in Bottom Sediments of the Mainstem Athabasca River System in the AOSERP Study Area
Resource
Dredged sediments and sediment cores were collected from sites along the Athabasca River system from between Fort McMurray and the confluence of Riviere des Rochers with the Slave River
Hemlock Woolly Adelgid
Resource
The hemlock woolly adelgid ( Adelges tsugae) is an introduced pest of hemlock trees in eastern Canada and the eastern United States. Hemlock woolly adelgid is also present in British Columbia but is a...
Herald Oilfield Service Reclamation Project
Resource
The Herald Reclamation Project began in the summer of 1989 and, to date, has involved clean up of a 2 acre oil spill, salvage of metal equipment used by a now defunct oil cleaning business, and proper...
High-Resolution Interpolation of Climate Scenarios for Canada Derived from General Circulation Model Simulations
Resource
Projections of future climate were selected for four well-established general circulation models (GCMs) forced by each of three greenhouse gas (GHG) emissions scenarios recommended by the...
How Climate Change Might Affect Tree Regeneration Following Fire at Northern Latitudes: A Review
Resource
Climate change is projected to increase fire severity and frequency in the boreal forest, but it could also directly affect post-fire recruitment processes by impacting seed production, germination...
How Does Canada Report on Forest GHG Emissions?
Resource
Each year, the Canadian Forest Service (CFS) provides estimates of the amount of carbon in our managed forests and the changes in these amounts over time. Environment and Climate Change Canada (ECCC)...
How Woodland Caribou use Post-fire Landscapes in Northeastern Alberta
Resource
To examine the effects of forest fires on woodland caribou, we collected GPS location data on five caribou ranges in northeastern Alberta.
Human Health Monitoring Program: A Summary of Findings and Recommendations
Resource
Data base and a series of maps on where certain diseases, conditions and visits to physicians and hospitals were reported. Assembling an extensive environmental data base was more difficult than expec
Human System Alberta Oil Sands Environmental Research Program 1975-1980: An Integration and Synthesis of Research Results
Resource
Describe, ananlyse, and interpret the socio-economic changes which had occurred in Fort McMurray from development of Suncor and Syncrude operations and assess changes in relation to development stages
Hydrotechnical Research in the Alberta Oil Sands
Resource
Hydrotechnical research in the Alberta Oil Sands has been oriented toward establishment of baseline (pre-development) environmental conditions and identification of contaminant transport mechanisms
Impact of Air Pollutant Mixtures on Forest Vegetation and Soils
Resource
No impact on jack pine physiology was found when concentrations of the dominant pollutants from Oil Sands operations equivalent to 104 years of soluble disposition were added to intact soil cores
Impacts of a Stump Uprooting Operation on Properties of a Calcareous Loamy Soil and on Planted Seedling Performance
Resource
Six hundred Douglas-fir (Pseudotsuga menziesii) and 600 lodgepole pine (Pinus contorta var. latifolia) seedlings were planted on seven plots in a cutover north of Golden, British Columbia, to...
Impacts of Blading and Burning Site Preparation on Soil Properties and Site Productivity in the Sub-Boreal Spruce Zone of Central British Columbia
Resource
We investigated soil factors and tree growth on sites that were clearcut during the 1970s and early 1980s and were subsequently site prepared with either blade scarification (blading) or prescribed...
Impacts of Climate Change on Photosynthesis and Carbon Sequestration / Impactes des changements climatiques sur la photosythèse et le piégeage du carbone
Resource
Global warming may cause photosynthesis to start earlier. As the climate warms, spring arrives earlier and fall ends later. This change in temperature affects how trees grow. Gretta Goodine of the...
Impacts of Cross-Contour Skidroads on Properties of a Gravelly Sandy Loam Soil and on Planted Seedling Performance
Resource
Soil conditions, growth of 1200 planted seedlings each of lodgepole pine ( Pinus contorta var. latifolia) and Douglas-fir ( Pseudotsuga menziesii), and development of other vegetation were studied to...
Impacts of Different Methods of Mechanical Site Preparation on Foliar Nutrients of Planted White Spruce Seedlings
Resource
The impacts of different methods of mechanical site preparation (MSP) treatments on foliar nutrients of planted plug+ 1 white spruce seedlings were examined at two mixed-wood boreal forest sites (Judy...
