We're wrapping up an eventful summer at the River Park!

From the Grand Opening of the Birdwing Open Air Classroom, to Exec Treks with our Executive Director, to launching the Citizen Science Monitoring Program, we've loved every chance to build connections between you, the community, and the River Park.

Now we're looking to Fall and even more exciting events! We're thrilled to host explorer and bestselling author Helen Thayer this month for a very special edition of DMFtalks. The River Valley Fest is coming up in October -- and we look forward to seeing many of you there! Be sure to register if you haven't already!

And of course, we have our Second Saturday ranger-led walks, another Full Moon Hike on the 7th, birdwatching at the lagoon, yoga on the beach...even as the season changes, we're not slowing down one bit! Fall is such a wonderful time in the River Park; we hope you're able to join us there soon.

Citizen Science Monitoring:
Off to a Great Start!

SDRVC and the San Dieguito River Park kicked off the Citizen Science Monitoring Project last month by surveying Argentine ants. A total of 24 volunteer citizen scientists, ranging from elementary and high school students to retirees, participated. They were led by local Argentine ant expert, Brian Sodeman.

Ant Surveys

Our teams of citizen scientists baited index cards and placed them at pre-designated locations. They used pecan sandies cookies and tuna in oil to test which was more effective in recruiting foraging ants.



The bait stations were left in place for a minimum of 45 minutes, after which the citizen scientist teams returned to take photos of the bait card, collect ant specimens, and record data. The ant specimens were then taken back to the office and identified under a microscope with the help of our local ant expert, Brian Sodeman. Citizen scientists also learned how to use GPS units to obtain latitude & longitude coordinates and how to record data.


Survey Results
The survey was intended to assess the presence of Argentine ants only, and does not provide an accurate measure of what native ants are present. Still, the teams detected a total of five native species throughout the majority of the preserve. Argentine ants were found at three of the 18 bait stations -- those located along a natural drainage near a residential development. This means that their level of invasion at this particular site is currently low, but future citizen science monitoring will be required to determine if they are expanding their range and impacting sensitive species.

Groups that provided support include:
  • Cuyamaca College Ornamental Horticulture Department
  • Garmin
  • Palomar Audubon Society
  • Patagonia
  • San Diego Foundation
  • SDG&E
  • Sierra Club North County Chapter
