Want to learn more about the tiny organisms that inhabit our waterways? Join Greenway Network's Larry Ruff for a Macroinvertebrate "Meet and Greet." He'll bring along some of the mighty macroinvertebrates that play important roles in our ecosystems.

According to the EPA's Factsheet on Water Quality Parameters, "Macroinvertebrates are small organisms without a backbone that are visible to the naked eye and are large enough to be easily collected. Analyzing the macroinvertebrates in a waterbody can help recognize signs of ecosystem health."
