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

Baseline states and aquatic habitats of major components of aquatic ecosystems in the southern portion of the AOSERP study area. Quantitative estimate of biological significance to the Athabasca River

Determine what spring spawners utilized these sections of the Athabasca and Clearwater rivers; locate and describe their spawning grounds; and describe the timing of spawning, hatching, and emergence

Fur value produced per square kilometre averaged $7.58 ($19.64/mi2) but ranged more than 500-fold, with much variation seeming attributable to trapper effort. 5% of traplines reported nil catches

Contains all available 1979 hydrometric data including daily discharges for streamflow stations with corresponding hydrographs and stage-discharge curves and water level information for gauged lakes.

Relationship between aquatic macrophyte growth and habitat factors found in the AOSERP study area is outlined, as are some implications of aquatic macrophyte inventory for management and revegetation

Classification system devised for mapping vegetation and surficial geology from 1:60,000 scale false colour infrared photographs; 1:50 000 base maps plus a vegetation and a surficial geology overlay

Ground surveys of vegetation and surficial geology generally confirmed that the classification systems used in the mapping accurately described and defined the ecological habitat features
