This National Wildlife Area was established in 1978 to preserve a unique group of marshes and swamps with exceptionally diverse fauna and flora. This protected area covers over 1,313 hectares (3,244 acres) on the south shore of Lake Saint-François, a natural widening of the St. Lawrence River.

Thanks to his geographical situation in the South of Quebec and in the nearness of the Saint François Lake, the wetlands and marshes which constitutes the Reserve is particularly remarkable for the wealth of his flora and his fauna. We find 600 botanical species there, about twenty which are rare or endangered and, in certain cases, unique in Quebec. The environment offers food and shelter to numerous animal species among which some in danger, 16 species of amphibians, 8 of reptiles, 223 of the birds and 53 of mammals.

Unlimited Ducks widely contributed in the 1980s to make the town and country planning lining the Saint-Francis Lake, inside and outside of the limits of the Reserve. These numerous arrangements contribute to the presence of diverse species. To discover more about the biodiversity of the reserve, a conducted tour in canoe, in rabaska boat or in sea kayak is imperative. The Canadian Service of The fauna prepared lists of birds, animals, as well as trees and shrubs which we can find on the territory. These lists can be used for your information or still, to note your own observations. Copies are available at the desk and is free of charge.
