Waterfowl and mammals harvested and trapped at various locations in the oil sands region and in reference locations are assessed for contaminant burdens and toxicology. Wildlife samples are obtained from local hunters and trappers. Tissue samples are analysed for concentrations of oil sands-related contaminants (heavy metals, polycyclic aromatic hydrocarbons, and naphthenic acids). Dead and moribund birds collected from tailing ponds are also evaluated for levels and effects of contaminants.

This record contains information on the samples collected and the intended parameters for analysis from sediment cores collected as part of this project including bacteria, chemistry, stable isotopes, fatty acids, or meiofauna.

The national agricultural ecumene includes all dissemination areas with 'significant' agricultural activity. Agricultural indicators, such as the ratio of agricultural land on census farms relative to total land area, and total economic value of agricultural production, are used. Regional variations are also taken into account. The ecumene is generalized for small-scale mapping.A new version of the agricultural ecumene is generated every census years (in vector format) since 1986.This file was produced by Statistics Canada, Agriculture Division, Remote Sensing and Geospatial Analysis section, 2017, Ottawa.

This dataset includes water chemistry data collected from five of the six lakes as part of the Northwestern Ontario Size Series project in 1987 and 1990 including species of nitrogen and phosphorus, carbon, chlorophyll a, conductivity, soluble reactive silica, chloride, sulphate, conductivity, sodium, potassium, magnesium, calcium, pH, alkalinity and organic acids

Pacific Herring spawn index data for British Columbia from 1951 to present. Note that the spawn index is a relative index of spawning biomass. In addition, “NA" indicates that data are unavailable because they are either incomplete or withheld; contact the custodian for more information. For the "Region" column specifically, "NA" indicates that the location is outside stock assessment region boundaries. There are a few caveats to consider when interpreting Pacific Herring spawn index data, which are discussed in the technical report (see supporting documents).

The health of individual amphibians, amphibian populations, and their wetland habitats are monitored in the oil sands region and at reference locations. Contaminants assessments are done at all sites. Amphibians developing near oil sands activities may be exposed to concentrations of oil sands-related contaminants, through air emissions as well as water contamination. The focus of field investigations is to evaluate the health of wild amphibian populations at varying distances from oil sands operations. Wood frog (Lithobates sylvaticus) populations are being studied in Alberta, Saskatchewan and the Northwest Territories in order to examine the relationship of proximity to oil sands activities and to prevalence of infectious diseases, malformation rates, endocrine and stress responses, genotoxicity, and concentrations of heavy metals, naphthenic acids and polycyclic aromatic hydrocarbons.

Plant health assessments and vegetation surveys are undertaken at both terrestrial and wetland sites in the oil sands region and in reference areas. Plant monitoring is being conducted for biodiversity and contaminants, and because plants are important both as wildlife habitat and as traditional-use species. Plant and soil samples are collected at monitoring sites near and at varying distances from oil sands operations. Plant tissues are being examined for levels of naphthenic acids (NAs), polycyclic aromatic hydrocarbons (PAHs) and heavy metals. Plant indicator species include Vaccinium spp. (blueberry), Ledum groenlandicum (Labrador tea), Arctostaphyllos uva-ursi (common bearberry), and Cornus canadensis (bunchberry). Soil samples from riparian banks and boreal forest locations are also collected for greenhouse studies. These experiments evaluate the uptake, distribution, and toxicity of the contaminants in plant tissue.

This data shows anthropogenic polyline disturbance features. Features were digitized using high resolution satellite imagery and orthophotos. Features from the National Road Network (NRN) and the National Railway Network (NRWN) were adapted and included. The following data was not included in the dataset: proposed features.Table 1.
