The Committee has brought together a group of biological scientists from all across Canada to give us their views on our direction and the questions we should be asking over next three to five years.

Laboratory studies were conducted during 1976 to investigate native grasses and legumes potentially useful for revegetation on various soils with and without the addition of fertilizer.

Soil morphology, site descriptions, and physical and chemical data for 130 soil profiles from the AOSERP study area are presented.

Recurring patterns of soils, landforms, and vegetation were delineated. The information was transferred first to 1:50,000 preliminary maps and then to eight 1:126,720 maps which accompany this report

Samples were taken from eight mineral and eight organic soil profiles. In addition, samples of parent materials from eight mineral soil sites were taken for analysis.

About 150 townships were field checked during the summer field season, and samples were taken from 44 mineral and 20 organic soil profiles

The emphasis in this inventory is on soils and the landforms on which they occur; both are indicated on maps. Air photo interpretation and field checking have been completed

Mine depressurization groundwater was acutely toxic to the three species of invertebrates tested. The 90 d LC50 was 8.5 to 9% for rainbow trout, 13.2% for lake chub, and 5.8% for white suckers.

Benthic macroinvertebrate and fish catch data from the Christina, Gregoire, and Hangingstone rivers
