ResumoNinety-six species of aquatic plants have been recorded for 21 lakes of Gatineau Park, located in Pontiac and Gatineau Counties, Quebec as a result of a field survey conducted in 1971 and by examination of herbarium specimens.Fifty-two species were the most recorded for any lake; two lakes had fewer than 10 species.The diversity found in lakes so close together is attributed to the recent (11,600 Before Present (B.P.)) denuding of the area by the Wisconsin Glaciation followed by the inundation of some, but not all of the lakes, by the Champlain Sea.The present distribution of aquatic plants reflects the isolated positions of some lakes relative to others, the limited accidental transfer of aquatic plant material to lakes of higher elevation, and the short growing season.
