From Wikipedia, the free encyclopedia
Natural Bridges State Marine Reserve (SMR) is a
marine protected area located at the
northern edge of Santa Cruz, California and
approximately 75 miles (121 km) south of San Francisco.
The SMR covers 0.58 square miles (1.5 km2)[1] and all
living marine resources are protected within the reserve.[2]
History
The Natural Bridges SMR was established in September 2007 by the
California Fish and Game Commission. It was one of 29 marine
protected areas adopted during the first phase of the Marine Life Protection Act
Initiative. The Marine Life Protection Act Initiative (or
MLPAI) is a collaborative public process to create a statewide
network of marine protected areas along the California
coastline.
Geography and Natural
Features
Natural Bridges SMR is adjacent to Natural Bridges State Beach
and Wilder Ranch State Park.
This marine protected area is bounded by the mean high tide line
and a distance of 200 feet (61 m) seaward of mean lower
low water between the following two points:[3]
- 36° 57.90’ N. lat. 122° 07.65’ W. long.; and
- 36° 57.00’ N. lat. 122° 03.50’ W. long.
Habitat and
Wildlife
Dramatic wave-cut platforms, exposed rocky cliffs, salt marsh, and sandy and
rocky shores provide habitat for a wide range of species that
inhabit the Natural Bridges area. These habitats include sandy
beach, rocky intertidal, and surfgrass.[4]
Recreation and Nearby
Attractions
Adjacent to Natural Bridges SMR is Natural Bridges State Beach
which features tidepools and the Monarch Butterfly Natural
Preserve. The Monarch Grove is home to migrating monarch butterflies from mid-October
through the end of February. Docent led butterfly, tidepool and
nature trail tours are available.
Also adjacent to Natural Bridges SMR is Wilder Ranch State Park
which has 34 miles (55 km) of hiking, biking and
equestrian trails. Historic farm buildings have been restored and
the park conducts tours and living history demonstrations. The University of California at Santa Cruz’s Long
Marine Laboratory and its public aquarium, the Seymour Marine
Discovery Center, are also adjacent to the Natural Bridges SMR.
Long Marine Laboratory is an oceanside research and educational
facility. Limited tours are offered to visitors to the Seymour
Marine Discovery Center.
California’s marine protected areas encourage recreational and
educational uses of the ocean.[5]
Activities such as kayaking, diving, snorkeling, and swimming are
allowed unless otherwise restricted. As a fully-protected marine
reserve, harvest of marine life including fish, invertebrates, and
kelp is not allowed in Natural Bridges SMR.
Scientific
Monitoring
As specified by the Marine Life Protection Act, select marine
protected areas along California’s central coast are being
monitored by scientists to track their effectiveness and learn more
about ocean health. Similar studies in marine protected areas
located off of the Santa
Barbara Channel Islands have already detected gradual
improvements in fish size and number.[6]
