Sea Ranch is located in the North Central Coast region of California. This site is 0.4 mi southeast of the Sea Ranch Del Mar Mussel Watch site. Sea Ranch is one of 6 sites where Kinnetic Laboratories did experimental clearings (1m x 2m) in 1985 in the Endocladia/Mastocarpus and Mytilus zones to look at recovery rates within these species assemblages. This site receives low visitation by tidepoolers and abalone divers, and is accessed through The Sea Ranch community (private property). This gently sloping site consists of moderately uneven terrain, containing few cracks and folds.
