Sidney Island Shorebirds Survey peep counts.

The surveys are conducted along the sandspit and within a 96 ha lagoon that encompasses mudflats, eelgrass beds, and saltmarsh at the northwest end of Sidney Island, located in the Strait of Georgia, British Columbia. The survey counts numerate two species, Western Sandpiper (Calidris mauri) and...

These shorebird surveys are conducted intermittently at a series of sites near the town of Tofino on the west coast of Vancouver Island, British Columbia, during northward (April to May) and southward migration (July to November). This survey includes all shorebird species. Surveyors used...

The subjects of this study – the St. Lawrence (river, estuary and gulf) and the Ottawa and Richelieu rivers – present a range of natural shoreline habitats that are conducive to the flourishing of avian, aquatic and terrestrial fauna. Avian fauna, particularly migratory birds, use wetlands as...

Canadian Wetlands Inventory (CWI) data for the La Mauricie National Park. Created according to the method developed by the Canadian Wildlife Service, Quebec Region. Between 2003 and 2007, the Canadian Wildlife Service, Quebec Region (CWS-QC) produced wetland maps for several sites in Quebec....

Since 1988, the governments of Canada and Quebec have been working together to conserve, restore, protect and develop the St. Lawrence River under the St. Lawrence Action Plan (SLAP). One of the projects identified under the theme of biodiversity conservation is the development of an integrated...

Recent efforts to model spring breeding habitats of fish in the St. Lawrence have revealed significant gaps in land use descriptions for the floodplains of Lac Saint-Pierre. In order to fill these gaps, aerial photographs taken in 1950, 1964 and 1997 were assembled in mosaic fashion and then...

From August 10 to September 10, 2013, ground-based monitoring was significantly augmented at the Fort McKay South site (AMS13) to measure additional air pollutants and meteorological properties beyond what was available from the established long-term air quality monitoring in the area. This air...

To assess the toxicity of winter-time atmospheric deposition in the oil sands mining area of Northern Alberta, embryo-larval fathead minnow (Pimephales promelas) were exposed to snowmelt samples. Snow was collected in 2011–2014 near (< 7 km) oil sands open pit mining operations in the...

Parasite communities were examined in Johnny Darters (Etheostoma nigrum) collected from five localities in the St. Lawrence River in southwestern Quebec: two reference localities, one polluted locality upstream of the Island of Montreal and downstream of industrial and agricultural activity, and...
