Site description The Barre de Portneuf is a sandbar extending southward, from the mouth of the Portneuf River, into the lower St. Lawrence River, Quebec. The sandbar originates from the southern side of the mouth of the Portneuf River. It extends southward and upstream into the St. Lawrence River, for a distance of 4.5 kilometres and a maximum width of 250 metres. A bay is created between the mainland and the sandbar which is inundated at high tide, and is mixture of one-third Spartina salt marsh and two-thirds mudflats at low tide. The middle portion of the sandbar is colonized by xeric plant species associated with sandy areas (mostly sea lyme-grass) while small stands of conifers and alders are established on higher parts.
