Table 2. Observation sites for the eastern sand darter in Quebec according to different time period. The first shows the watercourses by hydrographic region. The next four columns present the observations of eastern sand darter by time periods, i.e.,1940 à 1959; 1960 à 1979; 1980 à 1999; 2000 à 2010.
