Shortjaw Cisco species at risk assessment 2001


Author(s): Steinhilber, M.

Year: 2004

Abstract:
the shortjaw cisco is considered "threatened" in Canada and has been approved for listing in "threatened" in Alberta. The Alberta designation is based on the restricted redistribution in this species in the province and its isolation from other populations. To date, it has been verified at only one locality - Barry Lake in the Canadian Shield region north of Lake Athabasca - although unconfirmed reports have also come from Lake Athabasca, Gregoire Lake, and Cold lake. The main objective of the work undertaken in 2001 was to search for other populations of shortjaw cisco in the province. Additional distribution data would assist in assessing the status of this species by providing 1) updated distirbution data, 2) a search effort context in which to evaluate the number of reported element occurrences, and 3) a baseline for evaluation of future distribution trends. Previous work on the shortjaw cisco in Barrow Lake determined that this population appears stable and is under little immediate threat.

Tracking changes in water quality due to catchment land-use and lake morphometry across spatial and temporal scales


Author(s): Taranu, Z. E.

Year: 2007

Abstract:
Past studies have shown that diffuse nutrient loading from agricultural activities is an important cause of lake eutrophication. The degree to which this relationship can be scaled-up (e.g. at an inter-regional scale) has not, however, been widely addressed. My thesis objectives were therefore to define the generality and the impact of agriculture land use and lake morphometry on lake water quality. Analyses along spatial and temporal scales were conducted to evaluate the significance of these effects. In the first manuscript, we tested whether agricultural activities explain a significant proportion of the variation in lake water quality at a broad inter-regional scale. The degree to which lake mean depth modulates this response was also assessed. From our meta-analyses of 358 lakes, we noted a significant correlation between total phosphorus concentration and the extent of agricultural catchment development. This relationship was further strengthened by including lake mean depth as a second predictor. We also observed among-study variability in the relationship between these three variables. Thus, although there is a general relationship between total phosphorus concentrations and our two predictors, agriculture catchment development and lake mean depth, regional baseline nutrient differences modify this relationship. To address the issue of lake morphometry more closely, we adopted a spatio-temporal approach to investigate whether the effect of agricultural catchment development on water quality differed between dimictic and polymictic Albertan lakes. We found that the correlation between surface water total phosphorus concentration and the percent of agriculture in a lake's catchment was strongly modified by lake mixis patterns (which in turn are related to morphometry). Furthermore, with our paleo-indicators of lake water-quality, the chironomid communities, we detected opposing responses between the dimictic and polymictic basins to temporal land-use change. We suggest that external nutrient loading exerts a more notable effect on dimictic lakes, whereas internal loading is more important in polymictic systems.

Traditional foods study literature review


Year: 2003

Abstract:
The purpose of this traditional foods study was to "provide baseline information regarding trace concentrations of metals in First Nation traditional foods to which impacts of future development activities can be compared, and to identify traditional use resources and food gathering areas." This study, which includes the First Nations of Fort McMurray and Chipewyan Prairie, is meant to complement an earlier northern study that had included the communities of Fort McKay and Fort Chipewyan. For information on trace metals in traditional foods, the literature reviewed included six environmental impact assessments, a report by the Trace Metals and Air Contaminants Working Group, several reports from the Northern River Basin Study, the NRBS Human Health Monitoring Program report, the Aquatic Resource Management Study report, the Lesko Study report, and the RAMP Report on Chemical and Biological Monitoring. A summary of metal contaminants found is provided for each report. For information on traditional use resources and food gathering areas, the authors also reviewed six environmental impact assessments, three traditional land use and occupancy studies done for the Forest management Task Force, and the Northern River Basins Study. The traditional use and knowledge, concerns, and recommendations from each are summarized. A section on information gaps notes that very little monitoring of metals in wildlife, fish, and vegetation has been done south of Fort McMurray. Indeed, there is very little information from which to build a baseline assessment. RAMP and TEEM do not actively monitor in the study area. The possibility for exposure to contaminants identified in environmental impact assessments was not followed up with sampling. No dietary studies have been completed on communities in the area. Furthermore, TLU studies done with Fort McMurray First Nation and Chipewyan Prairie First Nation have been industry initiated and may not reflect all the traditional knowledge available. Likewise, GIS data from ANDC/AlPac is ten years out of date and needs to be cleaned up to be usable. The report provides several recommendations towards completing a baseline study of the region and identifies gaps in the traditional knowledge presented in environmental impact assessments that should be filled to assist in the design of broader environment management programmes.

Traditional land use and occupancy study: Anzac, Gregoire Lake Reserve, and Fort McMurray; Janvier and Chipewyan Prairie; and Conklin Settlement: Final Report. Volume 1


Year: 1993

Abstract:
The Traditional Land Use and Occupancy Study (TLUOS) grew out of the Parallel Aboriginal Process to Participate in Alberta Pacific's Forest Management Task Force, which was signed by senior representatives of the Athabasca Native Development Corporation (ANDC), Alberta Pacific Industries Inc. (AlPac), and the Alberta Department of Environmental Protection. The Aboriginal forum process detailed in the above document commits to: assessment of previous and current levels and extent of utilization of wildlife by Aboriginal people in the target region of the FMA land base; and assessment and discussion of traditional aboriginal land use in each compartment so that this information may be considered in the Detailed Forest Management Plan and during the Public Involvement Action Plan. Timber harvest plans will be reviewed under the Parallel Aboriginal Process prior to their approval. This report is to be used in conjunction with "Mapping How We Use Our Land: Using Participatory Action Research"
