{ "currentVersion": 11.3, "cimVersion": "3.3.0", "id": 0, "name": "Zostera / Zostère", "type": "Feature Layer", "description": "An advisory process was conducted to determine whether eelgrass (Zostera marina) meets the criteria pertaining to ecologically significant species and community properties. Presented here is the information on the distribution of eelgrass beds in theEstuary and Gulf of St. Lawrencein Quebec and some elements of two studies about an area of interest, the future Manicouagan marine protection area. In general, eelgrass beds are geographically distributed throughout the Estuary and Gulf of St. Lawrence in the Province of Québec. The largest eelgrass beds are as follow: the bed off Manicouagan, the L\u2019Isle-Verte eelgrass bed in the lower estuary, the one off Île Crescent and in Aylmer Sound bay on the north shore Gulf, and the Cascapédia bed in Chaleur Bay. The total surface area occupied by the various eelgrass beds are as follows: in the upper estuary \u2013 53 hectares; in the lower estuary \u2013 937 hectares along the north shore and 1,340 hectares along the south shore; along the northeastern portion of the Gaspé Peninsula \u2013 837 hectares; in Chaleur Bay \u2013 3,266 hectares. As for the eelgrass beds along the middle and lower North Shore, the total area occupied is not known, but the beds that are known occupy over 3,000 hectares. The layer presents the information on the distribution of eelgrass (Zostera marina) beds in James Bay, Chaleur Bay, Estuary and Gulf of St. Lawrence according to a literature review of documents produced between 1987 and 2009. #Fra Un processus de consultation a eu lieu afin de déterminer si la zostère (Zostera marina) respecte les critères des espèces et des attributs des communautés d\u2019importance écologique. Ce document présente la distribution spatiale de la zostère dans l\u2019estuaire et le golfe du Saint-Laurent de la province de Québec et une partie des deux études concernant le site d\u2019intérêt de la future zone de protection marine Manicouagan. De manière générale, les herbiers de zostère sont distribués à la grandeur de l\u2019estuaire et du golfe du Saint-Laurent de la province de Québec. Les plus grands herbiers sont ceux situés dans les régions de Manicouagan et de L\u2019Isle-Verte dans l\u2019estuaire maritime, de l\u2019Île Crescent et de la baie d\u2019Aylmer Sound sur la rive nord du Golfe et celui de la Baie de Cascapédia dans la Baie des Chaleurs. La superficie totale estimée des herbiers de zostère de l\u2019estuaire moyen est de 53 hectares ; pour l\u2019estuaire maritime, elle est de 937 hectares pour la rive nord et de 1 340 hectares pour la rive sud. La superficie totale estimée est de 837 hectares pour la péninsule gaspésienne et de 3 266 hectares pour la Baie des Chaleurs. La superficie de l\u2019ensemble des herbiers de la Moyenne et Basse-Côte-Nord est inconnue mais celle des herbiers connus dépasse les 3 000 hectares.
