A three-year inventory of selected rare, endangered and sensitive bird species in the Athabasca Oil Sands area was completed in the late summer of 1977. Aerial and ground surveys were conducted

Imagery from both meteorological and environmental satellite sensor systems was analyzed to determine its applicability in monitoring weather conditions at the Alberta oil sands.

Growth of grasses and legumes in tailings sand, and the effect of adding materials such as peat and glacial till to tailings sand, were studied using lysimeters both indoors and in the field.

An aquatic biomonitoring program must be implemented to ensure that measures taken to protect the water systems are working, so that improvements may be made if need be.

A co-ordinated plan is proposed for the identification of toxic emissions from oil sand developments in the AOSERP study area based on interviews with over 40 specialists in various fields

Appreciable changes in biochemical functions in an epiphytic lichen, Evernia mesomorpha, were observed in response to controlled SO2 exposures even at a very low SO2 concentration (0.1 ppm)

A number of coniferous and deciduous species that had been growing on the Suncor tailings sand dike for five to seven years were fumigated with 0.34 ppm SO2 under controlled environmental conditions
