Defining Disturbance and Recovery: The Influence of Landscape Specific Ecological Responses to Oil and Gas Linear Disturbances in North Yukon
Resource
Across northern Canada evidence of oil and gas seismic exploration remains from the 1950's to current day. While many of these linear features are still visible, others can no longer be seen. Research...
Design and Performance Enhancement of Mine Drainage Settling Ponds in Alberta
Resource
There has been increasing concern in recent years regarding the environmental impact of sediment laden runoffs discharged from land disturbing activities in Alberta. Settling ponds represent the most...
Development and Application of Soil Quality Criteria for Alberta's Resource Extraction Industries
Resource
Soil quality criteria for Alberta's resource extraction industries were prepared by the Soil Quality Criteria Subcommittee of the Alberta Soils Advisory Committee. The document produced was intended...
Development of Soil Quality Criteria for Contaminated Site Remediation
Resource
There can be little argument that contaminants are now a ubiquitous presence in our environment. Though large-scale efforts to deal with contaminant issues have traditionally focused on water and air...
Disposal of Drilling Wastes in the Mountains
Resource
The foothills and mountain regions are extremely varied in soils, vegetation, climate and geology. Oil and gas drilling wastes must be contained ana then dispose □ of, despite of this extreme...
Do Highway Rights-of-way Have to be Dull?
Resource
Highway rights-of-way in Alberta, and elsewhere, are dull because they consist of limited, non-native species mixes that are frequently mowed. These rights-of-way are therefore not much more exciting...
Ecotypic Variation in the Reproductive Response of Poa alpina
Resource
In 1983 the Alberta Environmental Centre (AEC) at Vegreville began a program to develop licensed, commercially available seed varieties suitable for use in the reclamation of rangeland and man-made...
Effect of Grasses and Soil Amendments on Soil Aggregates and Aggregate Strength
Resource
Four solum and subsoil materials from Alberta were treated to determine if soil aggregation and aggregate strength could be increased to reduce succeptibility to soil compaction. Each soil was treated...
Effectiveness of Soil Conservation Procedures on Recent Major Pipeline Construction in Western Canada
Resource
The effectiveness of a soil conservation method employed on recent major pipeline construction in Western Canada was investigated. Prior to any major construction activities, topsoil was salvaged over...
Elk Winter Food Habits and Forage Quality Along the Eastern Slopes of Alberta (A Review)
Resource
A review of the limited number of studies on elk winter food habits along the Eastern Slopes of Alberta shows that elk prefer grasses and grasslike plants over shrubs. When available, rough fescue (...
Emerging Issues – Land Degradation
Resource
Problems associated with soil degradation have, in some parts of Canada, reached crisis proportions. Combatting these problems is a complex task involving the consideration of social, economic, and...
Environmenta1 Planning for Rights-of-way
Resource
A recent study (using a 10% stratified random sample) estimated the amount of area physically disturbed by energy related activity, to be 66,576 acres (26,963 ha) for a selective study area...
Environmental Fate and Transport of Organic Contaminants in Soils at Waste Disposal Sites
Resource
Current approaches for describing the environmental dynamics of organic constituents in complex waste mixtures are reviewed. Factors controlling equilibrium and nonequilibrium sorption of organic...
Erosion Monitoring on Mountain Foothills Waste Dumps
Resource
The erosion study was designed to examine the effects of the regraded configuration (i.e. slope angle, slope length), waste material characteristics, age since reclamation, amount of precipitation...
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...
Establishment of Trees and Shrubs on Mined Land in the Grande Cache Area
Resource
The Terrain Sciences Department of the Alberta Research Council has been conducting a reclamation research program at the operations of Smoky River Coal Limited in the Grande Cache area since 1972...
Evaluation of Alternative Procedures and Equipment for Conserving Topsoil During Pipeline Construction in Western Canada
Resource
Topsoil conservation has become standard practice on pipeline construction in western Canada over the last 30 years. Pipeline contractors have used a variety of procedures and equipment with different...
Factors Influencing the Native Species Invasion of a Reclaimed Subalpine Minesite Near Grande Cache, Alberta
Resource
Factors affecting native species invasion were studied on a subalpine minesite (Smoky River Coal Limited No. 8 Mine) in the vicinity of Grande Cache, Alberta. The site had been revegetated with...
Faro Mine Complex Revegetation Activities
Resource
In preparation for remediation and closure of the Faro Mine Complex (FMC), significant work has been completed to develop and test revegetation methods at the mine site. Development and implementation...
