Riparian areas are the green, vegetated areas on each side of streams and rivers. They serve many important functions, including purifying water by removing sediments and other contaminants; reducing the risk of flooding and associated damage; reducing stream channel and streambank erosion; increasing available water and stream flow duration by holding water in stream banks and aquifers; supporting a diversity of plant and wildlife species; maintaining a habitat for healthy fish populations; providing water, forage, and shade for wildlife and livestock; and creating opportunities for recreationists to fish, camp, picnic, and enjoy other activities.

[The vireo's] comeback may prove that habitat along streams in Southern California is recovering from the effects of pollution caused by decades of urban development. That is a critical indicator of environmental health in a state that has lost 97% of its riparian woodlands, more than any other state.
