Aquatic plants in Lake Superior Provincial Park in relation to water chemistry.

Abstract

Species of submersed and floating-leafed aquatic plants and chemical composition of the water were studied in 14 lakes on the Canadian Shield, Ontario. Most lakes were carbonate-poor and had typical softwater floras. Two lakes of high alkalinity contained several hardwater species that were rare elsewhere in the park. Winter de-icing salt affected water chemistry in several roadside lakes, but had little apparent influence on plant species composition.-from Authors
