San Diego Bay Native Oyster Living Shoreline

San Diego Bay was historically a shallow water system composed of significant intertidal habitat. However, decades of dredging and channelization have resulted in a loss of 42 percent of San Diego Bay’s shallow subtidal habitat and 84 percent of its intertidal mudflat habitat since the late 1800’s. These modifications and associated shoreline armoring have resulted … Continued
