Temporal changes (1970–2016) in St. Lawrence River wetlands were assessed between Cornwall and Québec to assess wetland response to cumulative anthropogenic pressures in the watershed. Emergent wetlands area and biomass of submerged aquatic vegetation (SAV) were contrasted among five regions subjected to sharply different water level/discharge regime (stabilized, semi-natural, tidal), nutrient concentrations and shoreline use (rural to urbanized). Between 1970 and 2016, over the growing season, St. Lawrence River mean water level have dropped and mean water temperature increased. Reductions in phosphorus concentrations were observed over time both in water and in SAV tissues, in phase with improvements of urban wastewater treatment and phosphorus reduction in upstream Lake Ontario.

The specific composition, biomass, vertical distribution and metal content of submerged and emergent aquatic plants in the St. Lawrence were evaluated. The riparian vegetation community of the St. Lawrence is characterized by the presence of extensive wetlands in the floodplain, a border of emergent plants and vast underwater meadows dominated by American wild celery (Vallisneria americana), a strong indicator species of metal concentration.

The St. Lawrence Action Plan (SLAP) 2011 to 2026 (see http://planstlaurent.qc.ca/en/home.html) is the latest Canada-Quebec Agreement on the St. Lawrence and builds on the four previous agreements implemented since 1988.

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 feeding and resting areas. These wetlands develop primarily in bays that are sheltered from currents and their flora varies depending on water salinity and the presence or absence of tides. In the lowlands of the St. Lawrence, which are washed by fresh and brackish waters, wetlands contain submerged and emergent aquatic plants in areas unaffected by tidal action and are dominated by the American bulrush in areas where tidal variations uncover muddy sediments.

Long-term freshwater quality monitoring data for over 40 sites in the St. Lawrence River basin for the past 15 years or longer for nutrients, metals, major ions, and other physical-chemical variables are included in this dataset. Monitoring is conducted by Environment and Climate Change Canada (ECCC) as well as through the Canada-Quebec Water Quality Monitoring Agreement and the St. Lawrence Action Plan to assess water quality status and long-term trends, detect emerging issues, establish water quality guidelines and track the effectiveness of remedial measures and regulatory decisions. Data for sites operated by the province are available from Quebec's Sustainable Development, Environment and the Fight against Climate Change Ministry.

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Nutrients in the St. Lawrence River indicator reports on the status of total phosphorus and total nitrogen concentrations along the St. Lawrence River. It rates total nitrogen and total phosphorus status based on whether total phosphorus and total nitrogen concentrations exceed Quebec's total phosphorus water quality guideline for the protection of aquatic life and a total nitrogen water quality guideline for the protection of aquatic life specific to the St. Lawrence River. Exceeding a water quality guideline suggests a greater risk to the health of the St. Lawrence River ecosystem posed by phosphorus and/or nitrogen.Information is provided to Canadians in a number of formats including: static and interactive maps, charts and graphs, HTML and CSV data tables and downloadable reports.

The main purpose of the Conservation Atlas of Wetlands is to develop a portrait of the wetlands of the St. Lawrence Valley using innovative mapping methods in order to favor bird conservation by helping land managers to make decisions about land use and bird habitat conservation. Another objective was to develop methods needed to allow a monitoring of the St. Lawrence Valley wetlands and make a link to a potential national mapping project of that type as an indicator on environment quality in Canada. The Atlas is considered a large-scale project because of the area covered, the great variability in the area’s characteristics and the various types of wetlands encountered. Using Canadian RADARSAT satellite images, along with other sources of information available (e.g., digital hydrological and hypsometric data) and data from Landsat-TM images, the mapping has required certain adjustments and the use of innovative methods.

Environment and Climate Change Canada (ECCC) has been monitoring levels of persistent organic pollutants and heavy metals in seabird eggs collected from the St. Lawrence River and Gulf of St. Lawrence, Canada, since the end of 1960s. Two sentinel species were selected to monitor aquatic ecosystem health and contamination based on their elevated position in the food web and relatively limited feeding range; the northern gannet (Morus bassanus) and the great blue heron (Ardea herodias) (Champoux et al., 2002; 2006; 2010; 2015; 2016 – available in supplemental information section *). Current avian monitoring is completed as part of the St. Lawrence Action Plan (2011-2026), a Canada-Quebec agreement that aims to conserve, restore, protect, and enhance the St. Lawrence (http://planstlaurent.qc.ca/en.html). Pollutants monitored include legacy organochlorine pesticides (e.g.

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 plan for the conservation of the natural environments and biodiversity of the St. Lawrence River. The identification of priority sites for conservation has been the first step of this planning exercise. Conservation planning of natural environments requires a reliable, accurate and up-to-date image of the spatial distribution of ecosystems in the study area.
