A QUANTITATIVE STUDY OF SHORELINE MARSH COMMUNITIES ALONG LAKE HURON IN ONTARIO

Abstract

In July 1978, twelve shoreline marsh areas were surveyed along the east coast of Lake Huron. The mean dry weight of each species was determined per unit area in every marsh, and the diversity and dominance indices were calculated. Sums of squares agglomeration technique showed that the two northernmost sites were the most distinctive floristically. Of the remainder, three of the more southern marshes located near the Bruce Nuclear Power Development clustered together into a separate group.
