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

Water quality of the Athabasca River within the oil sands area has been monitored since 1976. Several studies of benthic invertebrate communities have been conducted to provide descriptive information

Point measurements of maximum depth showed that over 50% of the rainstorms occur in June and July, with only a small percentage in April (5.6) and September (10. 1).

Research project set up to study the establishment and survival of ground cover vegetation on roadsides, utility rights-of-way, and non-cultivated disturbed areas in Alberta

By the fall of 1974 34 test sites had been obtained and on 27 of these at least some planting had taken place. In 1975 more small sites (see included map) were obtained and these also were planted
