Re: Macroinvertebratec study
My club has been volunteering for these through our local watershed council. We've been doing collections in the spring and fall, a river mapping project in the summer and a Stonefly search in January for the last couple of years. We collect bugs from sites the authority assigns to our group, bottle them and send them back for ID day.
On ID day we go through our collection, sort them into the various families and groups and attempt to Id them to species. The authority does a final ID and records all the data for the entire watershed.
Check to see if you have a group like this in your area or close; our watershed group provides all the needed equipment and training for the collectors.
Check their website; they may be able to steer you toward a like group in your area. Huron River Watershed Council is the group, you can check them out on Facebook...
