Join us to explore local biodiversity and contribute to real scientific research! Learn how to document plants, animals, and insects in your neighborhood, on campus, or in local parks. Your observations help scientists map biodiversity across San Diego County and contribute to the San Diego City Nature Challenge (April 24–27). You can also discover a variety of citizen science projects you can participate in any time, anywhere, and contribute to 2.5 M Acts of Science!
