Applaud Organizations for Protecting Rare Oysters

Target: California Coastal Conservancy and San Francisco Bay Living Shorelines Project

Goal: Thank the California Coastal Conservancy and the San Francisco Bay Living Shorelines Project for protecting endangered oysters

In 1893, Olympia oysters covered nearly 8,033 acres of bay waters near San Francisco, California. At about half of a million oysters per acre, it seemed like it would be impossible for these creatures to disappear. And yet by 1911, human overconsumption had nearly done just that. After the long and hard work of the California Coastal Conservancy and the San Francisco Bay Living Shorelines Project, the oysters have finally made a return. Thank these organizations for their work to restore these creatures to their rightful waters.

Not only is this great news for the oysters after they were eaten into near extinction, but it is also good news for the residents of California. Oysters provide many useful services for the areas they inhabit. They filter water by removing nitrogen and other pollutants, as a single oyster can filter 30 gallons of water per day. They also create reefs that form a natural barrier which protects the shoreline. Researchers have found a 30% decrease in dangerous wave energy in the areas where the oysters are coming back.

Additionally, the oyster reefs form an excellent marine habitat for many different animals. The California Coastal Conservancy observed an influx of birds to the area as well, as sign that there are more fish in the water attracting the attention of the fowls. All of these are great signs for the oysters and the residents of California.

Thank the California Coastal Conservancy and San Francisco Bay Living Shorelines for the time and money they poured into restoring these Olympia oysters to the bay waters. Their efforts have clearly paid off as oysters have returned and have been making the waters cleaner and better since their return.


Dear California Coastal Conservancy and San Francisco Bay Living Shorelines,

Thank you for your wonderful work done to restore the Olympia oysters to their natural habitats in the bay waters of California. After their disappearance in 1911 it seemed highly unlikely they would return, so it is great to see their return.

As I am sure you are aware, these oyster beds are very good for the local habitat. They filter the water, removing harmful pollutants and nitrogen. They also create reefs that serve as home to many animals as well as acting as a natural protective barrier for the shoreline.

Again, thank you for your efforts to save these creatures and protect the environment.
