In 2014, the San Dieguito River Valley Conservancy (SDRVC) launched the Citizen Science Monitoring Program at the San Dieguito River Park. Citizen science takes advantage of the fact that visitors to the River Park are constantly observing their surroundings as they hike, bike or ride their horse on our trails. This program offers residents, volunteers, trail users and other outdoor enthusiasts a way to actively contribute to the betterment of their local outdoor spaces; they can be a field scientist for a day. It also offers students, when combined with school and university programs, a great way to get hands-on learning opportunities.
