Early performance of some native and cultivated grasses on oil sands mine disturbance materials
Download1982
The adaptability of native and cultivated grasses to oil sands disturbance materials is being studied in a field trial in northeastern Alberta. The native grasses originated from the mountains and foothills of the province. The trial was established on blended materials consisting of native...

Establishment and survival of ground cover plantings on disturbed areas in Alberta. Progress Report #2. Revegetation of disturbed sites. such as power line rights-of-way and strip mines
Download1973
Introduction This the second in the series of progress reports on the non-cultivated disturbed areas revegetation project deals with powerline rights-of-way and to a limited extent strip mines. The previous report dealt with pipeline rights-of-way and tar sand mining areas. Powerline...

Establishment and survival of ground cover plantings on disturbed areas in Alberta. Report No. 1. Revegetation of disturbed sites such as pipelines, cutlines and stripmining areas
Download1973
Objectives: To determine which native plant species might be useful in the revegetation of disturbed sites such as pipelines, cutlines and strip mining areas. To make recommendations of which plants to include in further studies and to collect seed of these plants for future study.

Establishment and vegetation survey of 16 Pinus banksiana – dominated permanent plots for the Athabasca oil sands ecological monitoring project in 1981
Download1982
Sixteen, undisturbed, 5-hectare, permanent plots dominated by Pinus banksiana (jack pine) were established along an impingement gradient of atmospheric emissions from oil sands processing plants north of Fort McMurray in northern Alberta in August of 1981. Four plots were burned over by wildfire...

Minisonde data collected in the Athabasca Oil Sands area from 1975 to 1979 were analysed to determine regional values of roughness length (Zo). A rigorous selection re reduced the working data set to a small fraction of the original size. A least squares technique was used to determine from...
