  • The wetlands of the St. Lawrence

    Observations on the various types of wetlands and terrestrial environments, as well as  a survey of vascular plants, are now available on the Government of Canada website for sampling sites located along the St. Lawrence, from Cornwall to Trois-Pistoles, in the Îles de Boucherville and in Lake Saint-Pierre. Happy reading!

  • Two new guides for dredging and sediment management

    The first, Recommendations for the Management of Suspended Solids (SS) During Dredging Activities, provides guidelines on how to manage dredging activities so as to minimize the negative impact of increased suspended solids on aquatic life. The purpose of the second publication, Guide for Physicochemical and Toxicological Characterization of Sediments, is to standardize preparation and analysis methods for quantifying the substances found in sediments, as well as their toxicity.

  • Describing how fish use the shipping channel

    The Quebec Ministère de la Forêt, de la Faune et des Parcs conducted the first inventory of the shipping channel of the St Lawrence River between 2007 and 2009 in order to characterize the fish community occupying this mysterious habitat. Whereas the channel had been considered a wildlife desert, the inventory showed that it is frequented by 27 fish species, some of them prized by fishermen or classified as at risk. Another interesting result is that this fish community is distinct from those in other habitats in the St. Lawrence River.

  • Knowledge exchange between researchers and experts on Lake Saint-Pierre

    A new fact sheet presents the work of a recently established knowledge exchange group on major ecosystem changes in Lake Saint-Pierre. The purpose of their discussions is to determine the possible causes of the degradation of the water quality, habitats and biodiversity of this fluvial lake of the St. Lawrence. The ultimate goal is to make recommendations on the restoration and research work that should be carried out as part of the next phase of the St. Lawrence Action Plan.

    This new strategy provides direction for the management of navigation activities, taking into account their economic, environmental and social impacts and addressing such emerging issues as the protection of marine mammals. The publication of this strategy by the Navigation Coordination Committee is part of the “Maintain the Navigation and Dredging Coordination Committees as Part of Integrated Management of the St. Lawrence” project.

  • New State of the St. Lawrence Monitoring Sheets

    Did you know that the aim of the State of the St. Lawrence Monitoring Program is to pool data on 21 indicators to create a global picture of the state of the St. Lawrence?

    Three of these indicators were recently updated: Beluga Whales, Great Blue Heron and water quality in the fluvial section. Monitoring sheets are prepared periodically to report on these updates, and this is done for each indicator in the program. You can consult these sheets in the “State Monitoring” section.

In 1988, the governments of Canada and Quebec began working together with various stakeholders to conserve, restore, protect and develop the St. Lawrence.
