Since 2003, Starr Ranch biologists have trained volunteers to use a standardized protocol to gather data on stream water quality and the impacts of urban run-off on the physical, chemical, and biological components of water quality in the creeks of Starr Ranch. Their results are sent to a statewide database. If you would like to volunteer with the annual stream bioassessment project, please contact Sandy DeSimone ([email protected]) at 949-858-0309.
