Research scientist Patty Gillis and her team are studying mussels in the Grand River near Brantford, Ont. As part of their work, they're also assessing the broader environment.

Brantford

A scientific team is using a method known as the cabin protocol to assess the health of the Grand River in Brantford, Ontario. The process involves collecting various insects, crustaceans, and mollusks from the riverbed, which are then identified and analyzed to evaluate the site’s ecological condition.

Researchers disturb the river sediment to collect samples of invertebrates, which are either taken to a laboratory or analyzed in a field lab. These organisms, living in different parts of the riverbed and feeding on various materials, provide important signals about the state of the river’s habitat.

How a team of scientists assesses the environment of the Grand River

This is for something we call a cabin protocol, so we can find all the different insects and little crustaceans and mollusks and we collect them all and then we collect all the ones we see and identify them and we use that to assess how healthy a site is or if there's changes in the little critters that dig into the sediment. So she's kicking up the sediment and we do it for a designated amount of time and then we take that sample that's collected back to the lab or in this case we're taking up to the field lab. And I'll kind of stand like right in front of it kind of like this kicking and like stirring up the bottom and you can see like all the dirt that I'm kicking up would then flow into the net. So all the invertebrates and little bugs that kind of live on the rocks in the bottom of the stream will be kicked up by my movement and the flow of the river should push them into the net for our sample. So just like the mussel tissues but these things are they're eating different things, they're buried in the sediment so they'll probably be a signal of what's going on in a different part of the habitat.
