Grondines Swamp (Sainte-Anne-de-la-Pérade)

The Grondines swamp consists of various fragile habitats, including 36 hectares (90 ac.) of intertidal zones and riparian forests. As a designated Exceptional Forest Ecosystem, the area’s forest stands include silver maple, black ash and the endangered butternut tree. Meanwhile, its intertidal segments provide shelter for waterfowl, like the Wilson’s snipe, and its high coastline hosts two threatened species of plants, the Victorin’s water hemlock and Parker’s pipewort. The property, nestled between Grondines and Sainte-Anne-de-la-Pérade municipality, holds some of the largest swamps, and one of the last integral stands of silver maple forest, on the shores of the St. Lawrence.
