In the summers of 1975, 1976, and 1977, several field investigations were carried out to determine the amounts of sulphur deposited in rain, in rain washing off trees, and by direct absorption of SO2 by soil. The impact of this sulphur deposition on soils in the AOSERP study area was also...

AOSERP project VE 7.1 was initiated to carry out field investigations in the revegetation of oi1 sands mine wastes (waste dumps and tailing sand) with trees and shrubs. The main objective of the project is to select species of trees and shrubs which are adapted to conditions on these waste...

One of the major environmental problems which arises with surface mining of the oil sands in the Fort McMurray-Fort MacKay area of Alberta is the permanent loss of the natural vegetation and the drastic change in the soils that supported it. It has been estimated that with a production target of...
