Species at Risk in the Sydenham

Home Species at Risk in the Sydenham

Species at Risk in the Sydenham

The Sydenham River supports an amazing diversity of aquatic life, it is home to at least 34 mussel species and 80 fish species. More than 20 fish and mussels in the Sydenham are Species at Risk (SAR). The watershed also supports many other semi-aquatic SAR including amphibians, turtles, snakes, and dragonflies. Some of these species are found nowhere else in Canada or remain in only a few locations globally. The Sydenham watershed is of global conservation concern for the persistence of these species.

From the 2018 Sydenham Action Plan:

Some of these species, such as Rayed Bean, occur in only one other location in Canada and persist in only a few locations in North America. The Salamander Mussel is found nowhere else in Canada and is considered globally vulnerable. The Northern Riffleshell population in the Sydenham River is one of only three remaining relatively healthy and reproducing populations globally. Consequently, the Sydenham River is of global significance to the conservation of these species.”
