Studies were continued in 1976 into the improvement of a five year old revegetated area on a tailings sand dike by the implementation of different fertilizer programs.

Ten sites in the system were sampled regularly for physical-chemical parameters, phytoplankton, zooplankton and benthic macroinvertebrates. Additional surveys were done for fish, aquatic macrophytes,

Peak discharge for the year was 22.5 m3/sec and the low 0.2 m3/sec. A total of 80 benthic macroinvertebrate taxa and 19 fish species were collected.

Of the 14 species seeded in 1976, only Lupine and the oat cover crop did not grow in 1977. A comparison of fall seeding versus spring seeding indicated that fall seeding could be successfully used

While a total of 11 species were encountered in the study area, only 6 were recorded in the upper diversion system (i.e., upstream of the Poplar Creek dam).

This monograph reports the selection of native and naturalized species suitable for use in revegetation of disturbed sites in the Athabasca Tar Sands Area. Growth chamber tests using 25 species

Objectives of the research were to study methods for the establishment of a stable vegetative cover that would prevent erosion of the slope and, in time, might become a self maintaining unit.

Study was designed to investigate the survival of selected organisms in Beaver Creek Reservoir during 1979 following discharge of mine depressurization water from the mining area into the Reservoir

Overall objectives of this study were to determine the abundance and diversity of terrestrial breeding birds and conduct waterbird inventories to determine what changes, if any, have occurred

Study to determine the scientific, technical and economic feasibility of establishing air pollution effect gradients using lichenological methods on a radially arranged pattern of observation sites
