Tidal marshes in the maritime coastal zone of Quebec

Tidal marshes in the maritime coastal zone of Quebec This dataset was designed for Environment and Climate Change Canada's (ECCC) National Environmental Emergencies Center (NEEC) for oil spill preparedness and response. The polygons from this layer come from the coastal ecosystems geodatabase as part of the Mapping of coastal ecosystems of the Estuary and Gulf of St. Lawrence project. This layer represents semi-vegetated (25-75%) and vegetated (75-100%) zones of which marsh vegetation is the dominant. The study area includes all of the estuarine and maritime coasts of Quebec, with the exception of certain sectors, including most of the Lower North Shore and Anticosti Island, with the exception of villages of Kegaska, la Romaine, Chevery, Blanc-Sablon and Port-Menier. Some islands off the estuary and gulf coasts are part of the region covered, such as Île d'Orléans, Isle-aux-Coudres, Île Verte and Île Bonaventure. The mapping of coastal ecosystems was carried out jointly by the Laboratory for Dynamics and Integrated Coastal Zone Management (LDGIZC) of the University of Quebec at Rimouski as part of the Coastal Resilience Project (https: //ldgizc.uqar.ca/Web/projets/projet-resilience-cotiere) funded by the MELCC; and by the Fisheries and Oceans Canada team, as part of its Integrated marine response planning (IMRP) component of the Oceans Protection Plan (OPP), with the objective of updating the Marine Oil Spill Preparedness and Response Regime of Canada. The master geodatabase of coastal ecosystems is hosted and distributed by UQAR on their SIGEC-Web mapping platform: https://ldgizc.uqar.ca/Web/sigecweb The characterization of marshes was mainly carried out using photo-interpretation of RVBI aerial photos acquired by DFO (2015-2020) and oblique photos taken by helicopter acquired by UQAR in 2017. This dataset also includes the information from validation stations visited by UQAR (2018-2020), used to validate and refine the photo-interpretation. 2025-04-11 Fisheries and Oceans Canada LouisDavid.Pitre@dfo-mpo.gc.ca Nature and EnvironmentQuebec; Gulf of St. Lawrence; Estuary of St. Lawrence; Marsh; Tidal marsh; Salt marsh; SchorreAquatic ecosystemsAquatic wildlife Parent project publicationHTML https://open.canada.ca/data/fr/dataset/d8a6c6fd-76cc-4d68-a949-c4d80eb2f296 Tidal marshes DatasetSHP https://api-proxy.edh-cde.dfo-mpo.gc.ca/catalogue/records/30515586-404d-4e4b-8da1-b81ec0e32ac1/attachments/Marais_maritime_Tidal_marshes.zip Translation Dictionary of Tidal MarshesCSV https://api-proxy.edh-cde.dfo-mpo.gc.ca/catalogue/records/30515586-404d-4e4b-8da1-b81ec0e32ac1/attachments/Dictionnaire_dictionnary_marais.csv Tidal Marshes Data DictionaryCSV https://api-proxy.edh-cde.dfo-mpo.gc.ca/catalogue/records/30515586-404d-4e4b-8da1-b81ec0e32ac1/attachments/DictionnaireDonnees_Marais%20maritimes%20de%20la%20zone%20c%C3%B4ti%C3%A8re%20du%20Qu%C3%A9bec%20maritime.csv Tidal Marshes map dataESRI REST https://egisp.dfo-mpo.gc.ca/arcgis/rest/services/open_data_donnees_ouvertes/tidal_marshes_maritime_coastal_zone_quebec/MapServer Tidal Marshes map dataESRI REST https://egisp.dfo-mpo.gc.ca/arcgis/rest/services/open_data_donnees_ouvertes/tidal_marshes_maritime_coastal_zone_quebec/MapServer Credit and referencesPDF https://api-proxy.edh-cde.dfo-mpo.gc.ca/catalogue/records/30515586-404d-4e4b-8da1-b81ec0e32ac1/attachments/Cr%C3%A9dit_r%C3%A9f%C3%A9rences_credit_references.pdf Biological Sensitivity Mapping for Oil Spill Planning and Response, Quebec RegionHTML https://ouvert.canada.ca/data/fr/dataset/d8a6c6fd-76cc-4d68-a949-c4d80eb2f296
