State Marine Reserve - California
Emeryville Crescent State Marine Reserve preserves marshland on the east shore of San Francisco Bay. The 103.5-acre (41.9 ha) marsh stretches from the eastern approach of the San Francisco–Oakland Bay Bridge in Oakland to the foot of Powell Street in Emeryville. The reserve encompasses the entire Emeryville Crescent Marsh and is named as such for its crescent shape. It was established in 1985. Temescal Creek drains into the marshes near the Emeryville–Oakland border on the eastern midpoint of the marshlands. The wetlands are made up of native species of pickleweed, and are currently being threatened by Spartina, a non-native invasive species of Cordgrass. It has invaded 2.4 acres (0.97 ha) or 2.5% of the wetlands. There is an active abatement program consisting of aquatic herbicides. The park is often used as a recreational area by local fishers and dog-walkers.
