Found 10 records similar to Field data for the mapping of the Lake St. Pierre wetlands (St. Lawrence River), 2012
Observations on various types of wetlands, terrestrial environments, and vascular plants for 55 sites visited in 2012 and located in in the Boucherville Islands are included in this dataset. Since the 1990s, Environment and Climate Change Canada (ECCC) has been monitoring changes in wetlands under the State of the St. Lawrence River Monitoring program of the St. Lawrence Action Plan.
Observations on various types of wetlands, terrestrial environments, and vascular plants for 864 sites visited in 2000 and 2001 along the St. Lawrence River, between Cornwall and Trois-Pistoles are included in this dataset. Since the 1990s, Environment and Climate Change Canada (ECCC) has been monitoring changes in wetlands under the State of the St. Lawrence River Monitoring program of the St. Lawrence Action Plan.
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 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.
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.
To support the WAWA program at the Department of Environment and Local Government and alert primary users to the location of wetlands and possible regulatory requirements for land development. The wetlands map is intended for planning purposes only. The wetland boundaries are only approximate.
What? Water samples are being collected in various wetlands in Cape Breton Highlands National Park. When? The monitoring frequency for wetland water quality is annually with samples being collected in the spring of the year.
Wetland vegetation is strongly related to water level and nutrient availability. These variables can be influenced by many stressors including, acid deposition, long-range transport of air pollutants and climate change. Monitoring vegtation in wetlands will help us better understand changes observed in wetland water quantity and water quality. Monitoring occurs once every 5 years along 2 transects at each of the 10 wetland sites.
