Did you know that the types of bugs in a stream can be great indicators of the health of the stream? Join us as at Grass River Natural Area on Saturday, May 6th as we collect and ID macroinvertebrates from Cold Creek. One group of volunteers will meet at 8 am and go into the creek to collect the macros while another group meets at 10 am to pick through, sort and ID the macros at the center. You may volunteer for either group or stay all morning. Lunch is provided for this event. If you are interested please contact [email protected] to register and be sure to specify which time(s) you would like to volunteer for.
