San Diego River Citizen Science Surveys

During the twice a year RiverBlitz surveys, teams of citizen scientists survey the River in the City of Santee and San Diego for invasive plants, trash and site condition issues. We also partner with other organizations and survey more remote areas less frequently. This data is made available to the public and helps us to coordinate efforts to obtain a healthy, trash-free River through our advocacy, working with landowners, managers and agencies, and our award winning volunteer-based clean-up program. The surveys also track the quantities and types of trash entering the San Diego River from the watershed.

How it Works:

  1. Surveys take place on Saturdays and Sundays in April and October each year.
  2. Teams are assigned to sections of the River each of which take about 2 -3 hours to survey. Teams are joined by a trained leader, so no experience is necessary.
  3. Surveys record non-native plants, trash, and park problems.
  4. Data is compiled into a State of the River Report which is available to the public.
  5. Data guides future clean-up events, projects and other actions.

Team Leader Training for the surveys are held in March and September! Email to learn more and to sign up for the next training.
