Interim report on small mammal populations and related tree damage in the AOSERP study area, October and November 1977
Download1977
The afforestation program in the Athabasca Oil Sands area has been only moderately successful, because of the high mortality of the planted seedlings--much of which Is believed to be the result of high levels of small mammal damage. The objectives of the present study were: (1) to determine the...

Interim report on symptomology and threshold levels of air pollutant injury to vegetation, 1975 to 1978
Download1979
Malhotra, S. S., Addison, P. A.
Six boreal forest plant species were fumigated in a newly developed environmental growth chamber with SO2 control capability,for up to 40 days at 0.34 ppm SO2. All species showed a gradual decline in CO2 gas exchange which was related to symptom development characteristic of SO2 toxicity. Paper...

Interim report on symptomology and threshold levels of air pollutant injury to vegetation, 1978-79
Download1979
Malhotra, S. S., Addison, P. A.
The dominant woody boreal forest plant species were fumigated with 0.34 ppm SO2 under controlled conditions in the laboratory in order to rank their physiological and visual sensitivities to the air pollutant. Deciduous trees and shrubs were much more sensitive than conifers, presumably because...

Interim report on the acidification of Lake 223, experimental lakes area: Background data, the first year of acidification (1976), and pilot experiments
Download1979
Wagemann, R., Hesslein, R. H., Schindler, D. W.
At the outset of AOSERP there was considerable concern that significant quantities of acid precipitation and heavy metals emanating from oil sands plants might adversely affect lakes near the oil sands area. Thus, the Aquatic Fauna Technical Research Committee initiated this project with the...

Lindsay, J. D., Turchenek, L. W.
Soil mapping of the AOSERP study area using the ecological or biophysical approach to land classification was continued in 1978. Work consisted of air photo interpretation, field checking, preparation of interim maps, and analysis of soil samples. About 150 townships were field checked during...

Inventory of selected raptor, colonial, and sensitive bird species in the Athabasca oil sands area of Alberta
Download1980
Ealey, D., Beaver, R., Munson, B., Fyfe, R.
A three-year inventory of selected rare, endangered and sensitive bird species in the Athabasca Oil Sands area of northeastern Alberta was completed in the late summer of 1977. Aerial and ground surveys of the Alberta Oil Sands Environmental Research Program (AOSERP) study area and selected...

Inventory of water use requirements and effluent discharge characteristics related to oil sands development
Download1980
An inventory of historical data on water use requirements and effluent discharge characteristics related to oil sands developments has been collected and tabulated. The inventory data indicate that surface water bodies are the main sources of the water supply and main recipients of effluent. ...

Investigations of the spring spawning fish populations in the Athabasca and Clearwater Rivers upstream from Fort McMurray: Volume 1
Download1979
Fisheries investigations were undertaken in the spring of 1978 (28 April to 25 June) in the Athabasca and Clearwater rivers upstream of Fort McMurray. The major objectives of the studies were to determine what spring spawners utilized these sections of the Athabasca and Clearwater rivers; to...

Lake acidification potential in the Alberta oil sands environmental research program study area
Download1979
Numerous lakes in Scandinavia and eastern North America have been damaged by acidic precipitation induced by anthropogenic oxides of sulphur and nitrogen. On first approximation, lakes near present oil sands operations would not be susceptible to acidification due to buffering provided by their...
