The Bergeronnes Marshes - Characterization of Important Coastal Habitats on the North Shore of the St. Lawrence Maritime 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 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.

It is possible to consult the datasets of the five other marshes that have been characterized as part of the project to characterize important coastlines:

• The Portneuf-sur-Mer Marsh

• The Mille-Vaches Bay Marsh

• The Pointe-aux-Outardes Marsh

• The pointe des Fortin marsh

• The Hickey marsh

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