Invasive Species – OVERVIEW

FOCA is very concerned about the potential impacts of introduced species and the effect they can have on our quality of life in Ontario. We have already seen the impacts from the many existing and looming invasive species introductions, including forest pests like the Emerald Ash Borer, aquatics like the Zebra Mussel and Asian Carp. These invaders have proven to alter the environment, damage our economy, and negatively impact our communities.

How can you help prevent the spread of invasive species in cottage country? Some general best practices are:

  • garden using only non-invasive plants
  • dispose of bait properly
  • buy firewood locally
  • inspect and clean your boat & motor when changing water bodies

Know what to look for and then take action!

February 2020 – Ontario’s Invasive Species Act, 2015 is the subject of an Environmental Bill of Rights posting open from February 13, 2020 until April 14, 2020, and relates to listing 13 more species as invaders within the Act. In addition, MNRF wants to determine if current education focused on Clean, Drain, Dry principles and practices should be made mandatory through regulation under the Act.

A Case Study:

September 2016 – (The University of Wisconsin) Trophic Cascades / Unforeseen impacts of invasive species – Milwaukee and the National Park Service has been helping to research the causes of botulism poisoning in birds along the shores of Sleeping Bear Dunes National Lakeshore Park. Leading this team is Dr. Harvey Bootsma. In describing the impacts of invasive species (quagga mussels) on the state of Lake Michigan, Dr. Bootsma was quoted saying:

“…if you went to Yellowstone Park and the bison were gone, there would be an uproar it would be really obvious and the Park just wouldn’t be the same. Yet the changes to Lake Michigan have been far more dramatic than that. If you looked at the change in species in the lake over the last 20 years – it’s a whole new system. Most of the public – and most policy makers – aren’t really fully aware how dramatic these changes are, and how fundamentally the lake has changed…”
