Friends of the San Juans removed a 55-cubic-yard berm that blocked flushing of the Neck Point coastal marsh on Shaw Island. With the assistance of partners and neighbors the tidal channels were restored to reestablish natural rates of tidal exchange, drainage, and access for fish and invertebrates and vegetation was replanted to enhance habitat for insects.
In a natural state tidal channels flood a salt marsh bringing in fish and crustaceans during high tides and flush the marsh during low tides. Coastal salt marshes are important for juvenile salmon because they are a source of insect prey. Before the berm was removed and the marsh reconnected, the Neck Point salt marsh only received marine waters at maximum tides and there were areas of stagnant freshwater. Since restoration fish have been observed using the marsh channels.
