Coal Oil Point Natural Reserve

17 Jul, 02 AM - 17 Jul, 10 AM

We plan to conduct a Pismo clam survey on the reserve. Pismo clam surveys use a modified version of the California Department of Fish and Wildlife’s survey methodology. Three parallel transects are surveyed at each location. Transects are run perpendicular to the ocean as far into the surf as possible during strong low tides (low water at least -0.5ft). Each transect is segmented in 3m sections, which are individually excavated and sieved through ¼ inch wire mesh to capture all clams present, down to 10mm. We measure and count all clams, which enables us to track recruitment and year class strength. Furthermore, at each site we collect abiotic data including: water temperature, sand samples for sediment grain size analysis, beach slope, human population density, and beach aspect. This survey methodology allows us to identify spatial differences in clam abundance and size structures across the state and to evaluate the role of potential drivers in controlling clam population sizes. This survey will be conducted by a team of 1 graduate student and 3 undergraduate students.
