The life cycle of the Olympia oyster, Ostrea lurida
O. lurida were harvested for a burgeoning West Coast market beginning in the late 19th century, but commercial stocks were depleted by the early 20th century. Habitat degradation and, in some cases, predation by introduced species and disease further contributed to the decline of this estuarine species (Polson et al. 2009). Many estuarine scientists are interested in restoring the species along the West Coast, as oyster beds provide habitat for a variety of other species and help stabilize the estuarine shoreline (e.g. Jackson et al. 2001, Ruesink et al. 2005).
