Canadian Wetland Inventory (CWI) ; Lac Saint-Pierre region

Canadian Wetlands Inventory (CWI) data for the lake Saint-Pierre region. 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. This mapping was carried out as part of the Canadian Wetland Inventory (CWI), an initiative launched in 2002 in order to classify wetlands into the five major classes of the Canadian Wetlands Classification System, namely: bogs, fens, marshes, swamps and shallow open water. The selected approach combines Landsat-TM/ETM and RADARSAT-1 satellite imagery with object-oriented image classification.

The mapped sites are situated in a variety of ecozones and represent different types of landscapes and ecosystems. These sites include Lac Saint-Pierre, Lac Brome, Montérégie, Lac Saint-François (Appalachians), Grande-Plée-Bleue, Montmagny, Cap Tourmente, Baie de l’Isle-Verte, La Mauricie National Park, Îles-de-la-Madeleine, Radisson and Eastmain. These twelve sites represent 4% of Quebec’s land mass. The method was tested in British Columbia (Vancouver) and in the Northwest Territories (Kendall Island).

A total of 8% of the territory constituted by the twelve sites is covered by wetlands, with the percentage for each site ranging from 2% to 15%. The classifications were validated using a method developed by CWS-QC which involves the visual interpretation of Landsat colour composites. Validation was performed in two ways: between wetlands and dry areas and between the five different types of wetlands. The overall accuracy for the first validation method ranges between 61% and 91%; for the second method, accuracy ranges between 47% and 98%.

Land cover of lake St.Pierre, 1950, 1964 and 1997

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 digitized, georeferenced and interpreted to categorize 28 fish habitat classes. For each of the three periods, interpretation made it possible to categorize and georeference polygons (e.g. wet meadows, perennial crops) and linear elements (e.g. windbreaks, riparian strips, roads) and to compile these with their properties (habitat class, length, perimeter, surface area). To facilitate and refine subsequent analyses, all polygons and linear elements were delineated with the aid of several layers of information, including the boundaries of regional county municipalities, drainage basins, several flood scenarios, and three large units: the north and south shores of Lac Saint-Pierre and the Sorel archipelago. This report describes the methods used and the constraints encountered; it also presents certain interpretation limits and a summary analysis of habitat classes in the three periods studied. A temporal trend analysis of habitat dynamics in the three periods has yet to be completed. Source files containing the data have been published and are available to anyone interested in land use in the floodplains of Lac Saint-Pierre or wishing to extend the study of changes in these landscapes and habitats over the past fifty years, depending on their field of interest (e.g. fish habitats, waterfowl nesting, agricultural landscape).

Assessment of changes in wetlands between 1964 and 2006 - Monteregie region

With the aid of aerial photographs from 2006 and the stereoscopic principle, the wetlands of Montérégie were mapped in 2007 as part of a project of the Monteregie Geomatics Agency (GéoMont). The Canadian Wildlife Service had indicated that it needed more up-to-date maps of the wetlands in the region, as well as the ability to evaluate the evolution of these environments to their present condition. Consequently, GéoMont was given a mandate to map the changes in wetlands in Montérégie.  

The goal of the project was to map the changes that took place in the wetlands of Montérégie between 1964 and 2006. This included: 

the mapping and statistical analysis of changes in the following protected areas: 
- Îles de Contrecoeur National Wildlife Area
- Îles de la Paix National Wildlife Area
- Lac Saint-François National Wildlife Area
- Mont Saint-Hilaire Migratory Bird Sanctuary
- Couvée Islands Migratory Bird Sanctuary
- Île aux Hérons Migratory Bird Sanctuary
- Philipsburg Migratory Bird Sanctuary

Also part of the project was the mapping and statistical analysis of changes in a hundred-odd sectors throughout the territory of Montérégie on the basis of a remote sensing inventory produced by the Canadian Wildlife Service. 

A number of recommendations were also made with respect to the monitoring of wetlands using geomatic capabilities.

The contract was completed ​​in 2008 by the Monteregie Geomatics Agency (GEOMONT). A report describing the methodology and results is available.
