Site description The three small Îles aux Loups Marins (Loups Marins Islands) and the large rocky flats (battures) that surrounds these islands are found approximately 8 km off the south shore of the St. Lawrence estuary, Québec. L'Islet-sur-mer, the closest town, is situated 23 km east of Montmagny. The large rocky flats are interspersed with muddy depressions. The small shale reef islands support mainly herbaceous vegetation. A large stand of Reed-Grass (Phragmites communis) occurs on the largest islets, as do alder and rose plants. Large willow trees are found near an uninhabited cottage on the largest islet.
