Research results of the Rideau River Biodiversity Project have shown that biodiversity in this section of the River is good.

Happy face.  Fish were most abundant and diverse in this section. Diversity peaked between Kars and Burritts Rapids because of large cattail beds, inlets and bays suitable for spawning.

Sad face.

A shortage of safe nesting sites and nursery areas for frogs and turtles may become critical as increased waterfront development eliminates suitable areas.
Happy face.   During the Project, the density of zebra mussels, an invasive exotic species, was low to moderate near Burritts Rapids. Density was higher between Kars and Long Island, where it was moderate to high.
   Water Quality
Neutral face.  Throughout the course of the Project, phosphorus levels were moderately elevated in this section.
   
Happy face.  The River's lowest levels of E. coli were found in this section during the Project. The levels of E. coli were low enough to permit swimming on most days.

  • The Baxter Conservation Area wetlands have extremely high aquatic plant diversity and abundance, and support a variety of fish, frogs, turtles, native freshwater mussels and birds.

  • A musk turtle, one of the rarest turtles in the Rideau River, was found in this section. The researchers were delighted to learn more about this turtle's distribution in the River.
