Variation in biomass of submerged and emergent aquatic vegetation in the St. Lawrence River

Variation in biomass of submerged and emergent aquatic vegetation in the St. Lawrence River The specific composition, biomass, vertical distribution and metal content of submerged and emergent aquatic plants in the St. Lawrence were evaluated. The riparian vegetation community of the St. Lawrence is characterized by the presence of extensive wetlands in the floodplain, a border of emergent plants and vast underwater meadows dominated by American wild celery (Vallisneria americana), a strong indicator species of metal concentration. Supplemental Information The St. Lawrence Action Plan (SLAP) 2011 to 2026 (see http://planstlaurent.qc.ca/en/home.html) is the latest Canada-Quebec Agreement on the St. Lawrence and builds on the four previous agreements implemented since 1988.
