"The Sydenham River Nature Reserve was established by Ontario Nature in 2016 and encompasses a 2.5 km stretch of the Sydenham River, one of the most biodiverse areas in Canada. The Sydenham River watershed supports the richest community of freshwater mussels in all of Canada with 35 native mussel species historically and 32 still considered extant today including 11 species at risk (SAR). In partnership with Ontario Nature, Fisheries and Oceans Canada (DFO) surveyed the entire length of river within the reserve in 2017 using a semi-qualitative timed-search method and a quantitative quadrat method. Across the five sites surveyed in the reserve, a total of 1,691 live individuals representing 23 species including 188 individuals of seven SAR were found. Of these individuals, 86.00% were found during the timed-search surveys. Mean site density (± 1 standard error) was calculated from the quadrat survey data and ranged from 0.10 (± 0.06) mussels/m2 to 1.04 (± 0.35) mussels/m2. While all of the species found during the survey of the Sydenham River Nature Reserve in 2017 were known to inhabit the Sydenham River, the data collected provide valuable baseline information on the freshwater mussel community found within the Sydenham River Nature Reserve to Ontario Nature"--Abstract, page v.
