  • 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.

  • A new approach for evaluating the effects of municipal effluents

    A study conducted under the St Lawrence Action Plan shows that treated wastewater dumped by municipalities, municipal effluent, has an adverse impact on the health of Yellow Perch in the St Lawrence. Contaminants, such as flame retardants and iron, have been found in the tissues of the perch analysed. A promising approach was developed for this study, providing for better evaluation of the effects of contaminants on living organisms.

  • 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.

  • Launch an online interactive version of the Atlas of Bank Restoration Sites of the St. Lawrence River

    The Atlas of Bank Restoration Sites of the St. Lawrence provides an inventory of those habitats disturbed by human activities in recent decades which have restoration potential. It is an interactive tool for proponents, government authorities, municipalities, conservation agencies, consultants and shoreline property owners who want to get involved in restoring disturbed wildlife habitats. The St. Lawrence Action Plan 2011–2026 is making the Atlas available in co-operation with the St. Lawrence Global Observatory.

  • Protected Areas on Private Land

    The Portrait of Protected Areas on Private Land has been published by Environment Canada’s Canadian Wildlife Service and the Ministère du Développement durable, de l’Environnement et de la Lutte contre les changements climatiques. The work leading to the production of the Portrait involved documenting 320 sites, covering a total area of 19,206.5 hectares, where conservation actions are being carried out.

  • Publication of the second Sustainable Navigation Strategy

    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.

  • Medications, hormones and other emerging contaminants

    A new fact sheet presents the concentrations of pharmaceutical and personal care products in the St. Lawrence and selected tributaries. This project was made possible by the pooling and joint interpretation of data collected by Environment Canada and the Ministère du Développement durable, de l’Environnement et de la Lutte contre les changements climatiques.

  • 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.
