PROJECT HIGHLIGHT:
This research project will advance our understanding of flow-ecology relationships along the Los Angeles and Santa Clara Rivers and of community perceptions and priorities for using flow as an innovative tool for restoring coastal rivers.
PROJECT SUMMARY:
Since the mid-to-late 20th century, wastewater discharges (effluent) have altered the flows of portions of the Los Angeles and Santa Clara Rivers in coastal Southern California. These discharges have at times perennialized formerly intermittent stream reaches, providing a consistent freshwater source to aquatic and riparian plants, insects, and birds. Currently a wide range of species, such as black phoebes, small minnow mayflies and arroyo willows, depend on this novel water source, which also supports some recreational uses and cultural connections.
This project will quantify flow-food web relationships (with a focus on birds, insects, and plants) and will explore how flow changes may affect human relationships to the rivers.
The work will help managers, tribes and nonprofits understand the implications of flow reduction scenarios and shape future decisions around restoration projects that enhance cultural connections, recreational opportunities and ecological conditions along these coastal rivers.
