Audubon study: Sausalito boat moorings pose threat to bay ecosystem

Richardson Bay, the inlet that opens into the San Francisco Bay from Sausalito and Tiburon, is home to multiple fragile ocean ecosystems that depend on eelgrass as a habitat, nursery, and food source.

According to a new study by Audubon California, the illegal mooring of private boats has caused significant harm to the eelgrass bed in that bay, with 25 to 41 percent of the seafloor habitat suffering damage.
