Deciduous trees and shrubs were much more sensitive than conifers, presumably because SO2 can enter broad leaves much more easily than needles. Jack pine was more sensitive than spruce
A set of 11 sites were established in the Alberta Oil Sands Environmental Research Program study area to provide baseline information on vegetation and soils with respect to air pollution impact
No measureable air pollutant effect was observed on either vascular or lichen communities at any site even though significantly high tissue pollutant concentrations were documented within 10km of GCOS
There was only very limited evidence of biological responses to increased pollutant content in spite of significantly higher pollutant levels in tissues close to existing industrial developments.
In this report an attempt has been made to relate the vegetation to a group of soil factors as well as climate and to examine soil texture in more detail and effects on plant communities and species
General survey of roadside vegetation done to see what species it consisted of. The results were then compared to the Department of Highways and Transport's records of seeding conducted from 1963-1972
Powerline rights-of-way were surveyed throughout Alberta to find out what vegetation was growing on them and if reseeding was required. The Whitewood coal mine at Wabamun was surveyed
Determine which native plant species might be useful in the revegetation of disturbed sites such as pipelines, cutlines and strip mining areas and collect seed for further studies
Reviews what is currently known of fish ecology and production of the Athabasca Basin, and includes discussions of fish production, sport and commercial use of fish populations
