Most macroinvertebrates are too small to noticeably stir the water's surface, but are large enough to see with the naked eye. They include small worms, mollusks, leeches, crustaceans, insects and insect larvae.

Macroinvertebrate monitoring can help characterize wetlands, but as a water quality indicator, wetland macroinvertebrate monitoring has not yet matured. It may be a great activity to engage your volunteers in if your primary goals are to raise awareness and characterize the wetland. Macroinvertebrate monitoring is a good way to teach volunteers about wetland ecology. And identifying some of the types of macroinvertebrates living in your wetland contributes to what you know about it.
