  • Update on river-borne nutrients entering the St Lawrence Estuary

    The accumulation of nutrients, what is called eutrophication, in the marine waters of the St Lawrence Estuary is raising concerns for aquatic life.  It results in proliferation of harmful algae, but also development of acidified areas poor in dissolved oxygen.
    Our researchers have been studying various aspects of this phenomenon. Using newly created digital tools, they have managed to assess the contribution of nitrate inputs to oxygen depletion and acidification of the water. These results are explained in two scientific articles. Consult the fact sheet!

  • Ecological monitoring program and biodiversity monitoring program

    An ecological monitoring program for the 8 National Wildlife Areas in Quebec has been developed by the Canadian Wildlife Service which presents the selected indicators and survey methodologies. Similarly, a biodiversity monitoring program is currently being developed for the entire province. These two programs will be implemented in a concerted manner to monitor biodiversity along the St. Lawrence River.

  • 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!

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