Measuring a Healthy Muskoka Watershed

 

2018 Muskoka Watershed Report Card Logo

 

How is our changing climate impacting Muskoka?  What does calcium have to do with Muskoka’s environmental health? And what the heck are benthic macroinvertebrates?On July 19, Muskoka Watershed Council will be answering these questions and many more through the release of its fifth Muskoka Watershed Report Card. Following its launch at Gravenhurst’s Discovery Centre, MWC’s interactive, online report card will be available at www.muskokawatershed.org.

 

Muskoka Watershed Council’s Report Card is a science-based evaluation of the health of our watershed using several environmental indicators. These indicators tell us something about particular aspects of that health — sort of like using blood pressure, pulse rate, temperature, weight and waist size as indicators of human health.

 

Produced every four years, using local, regional and citizen-scientist data and guided by expert scientific advisers, the Muskoka Watershed Council’s Report Card complies thousands of measurements into a simple and meaningful, interactive online report. The report card provides an “environmental snapshot” that will inform our own understanding of the watershed where we live, work and play, and will offer ideas and actions that individuals can undertake to protect it.

 

In 2018, four indicators will measure the health of the watershed and four indicators will consider potential threats to its health. Total phosphorus and calcium concentrations in lakes, benthic macroinvertebrates (or “bugs in the mud”) and the percentage of interior forest habitat will be reported on in the health indicator category. Threat indicators include climate change, invasive species and fragmentation, with a spotlight on species at risk. Each indicator is accompanied by a local initiative or citizen science program that you can get involved with, including the Lake Partner Program, the district’s benthic monitoring program, and becoming a PhragBuster with Georgian Bay Forever.

 

Species at risk are plants and animals that have been examined and determined to be in imminent risk of extinction within Ontario. Of the hundreds of species listed, at least 40 are known to occur in Muskoka, including the whippoorwill, eastern hognose snake, Blanding’s turtle, lake sturgeon, little brown bat, butternut and the rust-patched bumblebee.

 

That these species thrive here is wonderful, and keeping them here is a worthwhile goal. While it is known that many of these at-risk species are here, we do not know every place in Muskoka where they may be found. But we do know that in Muskoka, there are patches of habitat that would be suitable for each of them, and it turns out some parts of Muskoka provide a greater amount of suitable habitat for more species at risk than others.  By taking more care in places that might be home to species at risk we can enhance the chances that these species will continue to thrive here.

 

Dive deeper into the health of your Muskoka watershed, and look for the report card on July 19, at www.muskokawatershed.org.
