Streams play several important environmental roles as well as providing ecological services to people by contributing to drinking water supplies and providing recreational activities. By monitoring biological communities such as fish, benthic macro invertebrates (aquatic insects, worms, crustaceans, and mollusks), and amphibians and reptiles, the stream condition and water quality can be assessed. These indicator groups respond to the cumulative stressors in streams, their condition and whether they survive is a reflection on the health of the stream.
