Point Sierra Nevada is located in the Central Coast region of California, within the Monterey Bay National Marine Sanctuary. When the site was established in 1995, it was accessible only by crossing private property (Hearst Corporation), and received very little visitation (occasional trespassers). Then in 2005 the land was transferred to CA State Parks (now part of Hearst San Simeon State Park) and human visitation, particularly by fishermen, increased substantially. The site is fairly remote, which affords it protection from large numbers of visitors, but fishermen are now seen nearly every time the site is sampled. This gently sloping site consists of moderately uneven terrain, containing few cracks and folds.

Point Sierra Nevada biodiversity survey overview

Point Sierra Nevada is dominated by consolidated bedrock, and the area surrounding the site is comprised of a mixture of consolidated bedrock, boulder fields, and pebble beach. The primary coastal orientation of this site is southwest.

Long-Term Monitoring Surveys at Point Sierra Nevada were established in 1995, and are done by University of California Santa Cruz. Long-Term MARINe surveys currently target the following species: Chthamalus/Balanus (Acorn Barnacles), Mytilus (California Mussel), Hesperophycus (Olive Rockweed), Silvetia (Golden Rockweed), Mastocarpus (Turkish Washcloth), Mazzaella (Iridescent Weed), Phyllospadix (Surfgrass), and Pisaster (Ochre Star). In addition, motile invertebrates, barnacle recruitment, mussel size structure, and water temperature are monitored at this site. Click here to view Long-Term trends at this site.

Point Sierra Nevada long-term monitoring overview

Biodiversity Surveys were done by University of California Santa Cruz in 2001, 2003, 2004, and 2017. The Biodiversity Survey grid encompasses two sections that are approximately 12 meters (along shore) x 20 meters (seaward), and 15 meters (along shore) x 20 meters (seaward).
