  2. Amphibian surveys (spring-summer 2018) following habitat restoration work along three watercourses and in an agroforestry plot near Lake Saint-Pierre - Baie-du-Febvre Area

    Habitat management work has recently been conducted in the Lake Saint-Pierre area. Among these, three watercourses in the Baie-du-Febvre sector have been restored and an agroforestry plot was created at the Bertco farm in 2012. Wildlife monitoring was carried out in 2012 and 2018 in order to evaluate the response of wildlife to this habitat management. This report presents the results of the anuran (toad, frog) surveys conducted at these sites.

  3. Status of substances of emerging concern in bottom sediments and suspended sediments in the St. Lawrence

    In 2008, the St. Lawrence River component of Environment and Climate Change Canada’s (ECCC) Water Quality Monitoring and Surveillance Section made a commitment to provide scientific support to the Chemicals Management Plan (CMP). The CMP is a federal government initiative aimed at reducing the risks posed by chemicals to Canadians and their environment. This support generated a significant amount of funding, which, in conjunction with financial support from the St. Lawrence Action Plan (SLAP), made it possible to provide an initial portrait of substances of emerging interest in sediments and suspended sediments in the St. Lawrence River from samples collected in sediment traps.

  4. Neonicotinoid Insecticides: State of Knowledge of Their Potential Impacts on Aquatic Organisms

    Neonicotinoid insecticides were discovered in the 1980s and were introduced into the market a decade later. Since then, their use has become extremely widespread around the world, notably in response to the increasing resistance of insect pests to traditional insecticides such as organophosphates, carbamates and pyrethroids. Neonicotinoids are systemic insecticides that, unlike insecticides that remain on the surface of treated foliage, are absorbed by the plant and transported throughout its tissues, including the foliage, stems, roots, flowers, pollen and fruit

  5. Phytoplankton, toxic algae and zooplankton in the estuary and Gulf of St.Lawrence

    A close to 20 years monitoring of the phytoplankton and zooplankton community of the St-Lawrence estuary and Gulf shows that their global state remained fairly stable for the 2013-2017 period. If the biomass and the composition of the phytoplankton are highly variable, they did not show signs of anomalies for the most recent period. On the other side, zooplankton biomasses decreased slightly and its composition is changing, which could have impacts on the food web. On the toxic algae bloom side, there was a slight decrease in the last four years.

  6. Oceanographic processes: Temperatures, dissolved oxygen and acidification

    The summary indicator demonstrates that the temperature of the three levels of the St-Lawrence (surface, intermediate, deep) as well as the hypoxia and acidity conditions of the estuary remain at the intermediate level for the 2013-2017 period. However, a deteriorating trend of the general state was recorded from 2008 to 2012 and was mostly due to the high temperature of the deep waters which started to climb in 1915. The global tendency is also due to the decline of dissolved oxygen and the level of acidity in the St-Lawrence estuary, who both reached new records.

  7. Overview of the State of the St. Lawrence, 2019 edition

    The Overview of the State of the St. Lawrence, 2019 edition, takes stock of the freshwater and seawater ecosystem of the St. Lawrence River using indicators focusing on water, sediments, biological resources, banks, and uses. It also examines three key challenges that the St. Lawrence River is facing: nutrient overload from Lac Saint-Pierre, the acidification of water in the Gulf, and the impacts of climate change on the river’s tributaries. The overview is meant to be an information tool for the benefit of decision-makers and interveners with respect to the St. Lawrence River.

  8. Atlas of Sites of Conservation Interest in the St. Lawrence Lowlands – Methodology Report version 2, including Outaouais region June 2019

    One of the projects under the biodiversity conservation theme of the St. Lawrence Action Plan is the development of an integrated plan for conserving the St. Lawrence’s natural environments and biodiversity. Identifying sites of interest for biodiversity conservation was the first step in this integrated planning process leading to the production of the Atlas of sites of conservation interest in the St. Lawrence Lowlands. Conservation targets (coarse filter) selected for this atlas are woodlands, wetlands, open habitats (old fields, perennial crops), and aquatic environments. This report presents the methods that led to the production of this atlas.
