A review and assessment of existing information for key wildlife and fish species in the Regional Sustainable Development Strategy study area. Volume 1: Wildlife

Year: 2002

This report summarizes the life history and habitat requirements, distribution and population characteristics (e.g., size and trends) of key wildlife species and communities in the Regional Sustainable Development Strategy (RSDS) study area of northeastern Alberta. A summary of information on key fish species is presented in Volume 2 of this report. Key wildlife included 7 priority #1 species/communities (woodland caribou, moose, muskrat, fisher/small mammal, lynx/snowshoe hare, old growth forest bird community, and Canadian toad) and 8 priority #2 species/communities (black bear, beaver, river otter, ruffed grouse, pileated woodpecker, boreal owl, mixedwood forest bird community, and ducks and geese). Key fish included 2 priority #1 species (northern pike and walleye) and 4 priority #2 species (lake whitefish, Arctic grayling, longnose sucker, and burbot). The information presented in this report is organized into detailed species and community accounts. Data was compiled from numerous sources, including government, industry, university and private/ non-profit organizations. Over 300 published and unpublished reports were reviewed to assimilate the information presented in this report. Habitat/life history requirements for each wildlife species were summarized as general living, foraging, reproducing, protective/thermal cover and migrating/ moving habitat requirements. Habitat elements that characterize moderate-high suitability habitats were also identified based on the results of existing habitat suitability index (HSI) models. Population sizes and trends, as well as the natural variability in population size, were reported where possible. Limited information was available on the population dynamics of most species. Information on population trends was augmented by a discussion of habitat trends within the oil sands area using the results of Cumulative Effects Assessments for various oil sands development projects. Data collected from oil sands projects, as well as other sources, on species sightings/ occurrences and important habitat areas were mapped using GIS. Finally, information gaps pertaining to habitat use, habitat requirements, and population characteristics for each key species/ community were identified.

"This study examined water and sediment quality indicators in the area of Fort Chipewyan, Alberta. Data were analyzed and discussed in the contexts of water and sediment quality guidelines, wildlife contaminants, and ecosystem and public health.

Food habits of mink (Mustela vison) and otter (Lutra canadensis) in northeastern Alberta

Author(s): Gilbert, F. F.

Year: 1982

Scats of mink (Mustela vison) and otter (Lutra cawdensis) in northeastern Alberta contained different food items in different habitat types according to type of water body. Brook stickleback (Culaea inconstans) was the most frequently encountered food item in scats of both species from a drainage system dominated by lakes and for otter from a second drainage system dominated by streams. However, mink had varying hare (Lepusamericanus) as their primary food item by frequency of occurrencein this latter situation and mammalian items were significantly ( P < 0.01) more frequent. Otter scats contained more fish and invertebrates ( P < 0.01) and fewer mammals ( P < 0.01) and birds ( P < 0.05) than mink scats. Both otters and mink appeared to exploit avian species to a greater degree ( P < 0.01) in the lake-dominated drainage. The frequency of avain remains in otter scats was very high and probably reflected high utilization of breeding and moulting waterfowl.
