The Portneuf-sur-Mer salt marsh - Characterization of important coastal habitats on the north shore of the St. Lawrence Estuary

A project to characterize important coastal habitats on the north shore of the St. Lawrence Estuary was funded for a period of 4 years (2018-2022). The purpose of this project is to generate reference ecological data to draw a global portrait of the state of coastal marshes in the upper north shore sector of Quebec.

This dataset covers the Portneuf-sur-Mer swamp sector. In order to improve knowledge of this ecosystem, floristic and faunal inventories (ichthyological and benthic) have been carried out and the various abiotic factors characterized. A project carried out in parallel by the Comité ZIP de la Rive Nord de l'Estuaire broadened the characterization of the Portneuf-sur-Mer marsh by adding a geomorphological component. A characterization report including an intervention plan was thus produced and is available in this dataset.

It is possible to consult the dataset on the geomorphology of the Portneuf-sur-Mer marsh as well as the five other marsh datasets that were characterized as part of the project to characterize important coastlines:

• Geomorphological survey of the salt marsh and the sandspit of Portneuf-sur-Mer.

• The Pointe-aux-Outardes Marsh

• The Mille-Vaches Bay Marsh

• The Pointe des Fortin Marsh

• The Bays des Grandes and Petites Bergeronnes Marsh

• The Hickey Marsh

This project is part of the Coastal Environmental Reference Data Program of Fisheries and Oceans Canada.
