Characterization of important coastal habitats on the north shore of the St. Lawrence Maritime Estuary: Les Bergeronnes marshes

A project to characterize important coastal habitats on the north shore of the St. Lawrence Maritime Estuary was funded for a period of 4 years (2018-2022). The purpose of this project is to generate ecological reference data to draw a global portrait of the state of six coastal marshes, namely the marshes of Portneuf-sur-Mer (https://catalogue.ogsl.ca/fr/dataset/5374b582-43aa-4ffa-8361-4a0d9f1f6b8e), Mille-Vaches Bay (https://catalogue.ogsl.ca/dataset/f10f496a-acf4-4274-9c7b-7a005bcf54ed), Pointe des Fortin (https://catalogue.ogsl.ca/dataset/3b8c6d97-6eb8-4e8d-9869-ccb2b9bab5f3), Pointe-aux-Outardes (https://catalogue.ogsl.ca/fr/dataset/46d3ba2e-2fd3-4aad-a51a-f8343fbe6a73) and the bays of Grandes and Petites Bergeronnes.

This dataset covers two sectors in the municipality of Les Bergeronnes, two marshes located in the bays of Grandes and Petites Bergeronnes. In order to improve knowledge of these ecosystems, floristic and faunal inventories (ichthyological and benthic) were carried out and the various abiotic factors characterized. Geomorphological data has also been collected, but it is not included in this dataset. However, they remain available, contact the Comité ZIP de la Rive Nord de l'Estuaire (RNE) directly to access them. The ZIP RNE Committee holds orthomosaics of these two marshes as well as two ecogeomorphological boundaries (lower limit of marsh vegetation and coastline).

A characterization report of the floristic, ichthyological and geomorphological aspects of the Grandes and Petites Bergeronnes marshes is also available.

This project is part of Fisheries and Oceans Canada's Coastal Environmental Baseline Program under the Ocean Protection Plan.
