Curious about what critters live in your local streams and freshwater marshes? Come join Maine Audubon, Maine Department of Environmental Protection (DEP), and Presumpscot Regional Land Trust for a fun morning of catching and identifying macroinvertebrates at Mill Brook Preserve! Get hands-on training and learn how you can contribute to an important community science project, the Marsh and Stream Explorers, that acts as a screening tool for DEP’s water quality assessments. Be prepared to wade into shallow water as you net and handle macroinvertebrates!

We will meet at the parking area for the Northern Trailhead and go on a short walk from there. Wear clothes and shoes you’re comfortable walking in and potentially getting wet. Waders or muckboots are encouraged and some may be provided.

This event is free to attend, but registration is required.
