Action plan for the Sydenham River in Canada : an ecosystem approach. : CW69-21/34-2017E-PDF

"The Sydenham River in southwestern Ontario supports an amazing diversity of aquatic life. Located in the lower Great Lakes basin, the river contains the greatest diversity of freshwater mussel species of any watershed in Canada. At least 34 species of mussels and 80 species of fishes have been found here. Many of these species are rare and seventeen species, including eleven mussels and six fishes, have been assessed by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) as Endangered, Threatened or Special Concern. The majority of these species are protected under the federal Species at Risk Act (SARA) and seven freshwater mussels (Round Hickorynut, Kidneyshell, Northern Riffleshell, Snuffbox, Round Pigtoe, Rayed Bean and Salamander Mussel) and two fishes (Eastern Sand Darter – Ontario population and Northern Madtom) are the focus of this action plan. The present plan is guided by four SARA recovery strategies for these nine species and builds on the ecosystem-based Sydenham River Recovery Strategy completed in 2003"--Executive summary, p. iii.
