Invasive Species A Growing Problem In Muskoka

The District has identified more than 230 invasive species sites in Muskoka. That number is expected to jump significantly by year’s end.

That was the message Jamie Delaney, the District's manager of environmental compliance had for Bracebridge General Committee during their Tuesday morning meeting.

Delaney said that in Bracebridge the most common species are Japanese knotweed and phragmites. Within the boundaries of Bracebridge there are three identified occurrences of giant hogweed, which is potentially harmful to humans.

Delaney also showed the committee maps of both Bracebridge and Muskoka District that identified the 200 plus known locations of knotweed, phragmites and hogweed. He said the municipalities of Huntsville and Lake of Bays still need to be investigated and, as such, he expects the number of sites to increase.

He said the outbreaks in Bracebridge are not as bad as some parts of Muskoka, such as Georgian Bay Township.

Although hogweed is the most dangerous to people, Delaney said the biggest area of concern right now is with stopping the spread of phragmites. While Japanese knotweed has been spotted in Muskoka for more than 50 years, phragmites was unheard of here before roughly a decade ago. Its rapid spread is a significant cause of concern for the District.
