New and seasoned volunteers of all ages are invited to join us as we collect data for our biannual stream monitoring program. This year, teams will be collecting macroinvertebrates (creek "bugs") at three sites along Shanty Creek and then will return to the Grass River Center to sort through their critter samples. Pre-registration is required - email Emily at emily@grassriver.org. Note: new volunteers will be put into groups with more experienced volunteers. Dress for the weather, and bring hip waders if you have them (though we have more than enough pairs to loan out!)
