Santa Maria Creek biodiversity survey overview

The site is located along the shores of Drake’s Bay approximately ¼ mile southeast of the mouth of Santa Maria Creek. Point Reyes Peninsula offers this site some protection from the predominantly northwesterly winds and seas. This gently sloping site consists of moderately uneven terrain and is on a sedimentary rock platform which has numerous crevices and gullies. This site receives low visitation by tidepoolers

Long-Term MARINe surveys currently target the following species: Mytilus (California Mussel), Pelvetiopsis (Dwarf Rockweed), and Pisaster (Ochre Star). In addition, motile invertebrates and mussel size structure are monitored at this site. Click here for detailed intertidal monitoring protocols and additional information about the intertidal habitats of the San Francisco Bay Area National Parks.
